The RTC power domain in sun6i and newer SoCs manages the 16 MHz RC
oscillator (called "IOSC" or "osc16M") and the optional 32 kHz crystal
oscillator (called "LOSC" or "osc32k"). Starting with the H6, this power
domain also handles the 24 MHz DCXO (called variously "HOSC", "dcxo24M",
or "osc24M") as well. The H6 also adds a calibration circuit for IOSC.
Later SoCs introduce further variations on the design:
- H616 adds an additional mux for the 32 kHz fanout source.
- R329 adds an additional mux for the RTC timekeeping clock, a clock
for the SPI bus between power domains inside the RTC, and removes the
IOSC calibration functionality.
Take advantage of the CCU framework to handle this increased complexity.
This driver is intended to be a drop-in replacement for the existing RTC
clock provider. So some runtime adjustment of the clock parents is
needed, both to handle hardware differences, and to support the old
binding which omitted some of the input clocks.

These new RTC variants all have a single alarm, like the R40 variant.
For the new SoCs, start requiring a complete list of input clocks. The
H616 has three required clocks. The R329 also has three required clocks
(but one is different), plus an optional crystal oscillator input. The
D1 RTC is identical to the one in the R329.
And since these new SoCs will have a well-defined output clock order as
well, they do not need the clock-output-names property.

Pull netfs updates from David Howells:
"Netfs prep for write helpers.
Having had a go at implementing write helpers and content encryption
support in netfslib, it seems that the netfs_read_{,sub}request
structs and the equivalent write request structs were almost the same
and so should be merged, thereby requiring only one set of
alloc/get/put functions and a common set of tracepoints.
Merging the structs also has the advantage that if a bounce buffer is
added to the request struct, a read operation can be performed to fill
the bounce buffer, the contents of the buffer can be modified and then
a write operation can be performed on it to send the data wherever it
needs to go using the same request structure all the way through. The
I/O handlers would then transparently perform any required crypto.
This should make it easier to perform RMW cycles if needed.
The potentially common functions and structs, however, by their names
all proclaim themselves to be associated with the read side of things.
The bulk of these changes alter this in the following ways:
- Rename struct netfs_read_{,sub}request to netfs_io_{,sub}request.
- Rename some enums, members and flags to make them more appropriate.
- Adjust some comments to match.
- Drop "read"/"rreq" from the names of common functions. For
instance, netfs_get_read_request() becomes netfs_get_request().
- The ->init_rreq() and ->issue_op() methods become ->init_request()
and ->issue_read(). I've kept the latter as a read-specific
function and in another branch added an ->issue_write() method.
The driver source is then reorganised into a number of files:
fs/netfs/buffered_read.c Create read reqs to the pagecache
fs/netfs/io.c Dispatchers for read and write reqs
fs/netfs/main.c Some general miscellaneous bits
fs/netfs/objects.c Alloc, get and put functions
fs/netfs/stats.c Optional procfs statistics.
and future development can be fitted into this scheme, e.g.:
fs/netfs/buffered_write.c Modify the pagecache
fs/netfs/buffered_flush.c Writeback from the pagecache
fs/netfs/direct_read.c DIO read support
fs/netfs/direct_write.c DIO write support
fs/netfs/unbuffered_write.c Write modifications directly back
Beyond the above changes, there are also some changes that affect how
things work:
- Make fscache_end_operation() generally available.
- In the netfs tracing header, generate enums from the symbol ->
string mapping tables rather than manually coding them.
- Add a struct for filesystems that uses netfslib to put into their
inode wrapper structs to hold extra state that netfslib is
interested in, such as the fscache cookie. This allows netfslib
functions to be set in filesystem operation tables and jumped to
directly without having to have a filesystem wrapper.
- Add a member to the struct added above to track the remote inode
length as that may differ if local modifications are buffered. We
may need to supply an appropriate EOF pointer when storing data (in
AFS for example).
- Pass extra information to netfs_alloc_request() so that the
->init_request() hook can access it and retain information to
indicate the origin of the operation.
- Make the ->init_request() hook return an error, thereby allowing a
filesystem that isn't allowed to cache an inode (ceph or cifs, for
example) to skip readahead.
- Switch to using refcount_t for subrequests and add tracepoints to
log refcount changes for the request and subrequest structs.
- Add a function to consolidate dispatching a read request. Similar
code is used in three places and another couple are likely to be
added in the future"

Provide a place in which to keep track of the actual remote file size in
the netfs context. This is needed because inode->i_size will be updated as
we buffer writes in the pagecache, but the server file size won't get
updated until we flush them back.

Add a function to do the steps needed to begin a read request, allowing
this code to be removed from several other functions and consolidated.
Changes
=======
ver #2)
- Move before the unstaticking patch so that some functions can be left
static.
- Set uninitialised return code in netfs_begin_read()[1][2].
- Fixed a refleak caused by non-removal of a get from netfs_write_begin()
when the request submission code got moved to netfs_begin_read().
- Use INIT_WORK() to (re-)init the request work_struct[3].

Add a netfs_i_context struct that should be included in the network
filesystem's own inode struct wrapper, directly after the VFS's inode
struct, e.g.:
struct my_inode {
struct {
/* These must be contiguous */
struct inode vfs_inode;
struct netfs_i_context netfs_ctx;
};
};
The netfs_i_context struct so far contains a single field for the network
filesystem to use - the cache cookie:
struct netfs_i_context {
...
struct fscache_cookie *cache;
};
Three functions are provided to help with this:
(1) void netfs_i_context_init(struct inode *inode,
const struct netfs_request_ops *ops);
Initialise the netfs context and set the operations.
(2) struct netfs_i_context *netfs_i_context(struct inode *inode);
Find the netfs context from the VFS inode.
(3) struct inode *netfs_inode(struct netfs_i_context *ctx);
Find the VFS inode from the netfs context.
Changes
=======
ver #4)
- Fix netfs_is_cache_enabled() to check cookie->cache_priv to see if a
cache is present[3].
- Fix netfs_skip_folio_read() to zero out all of the page, not just some
of it[3].
ver #3)
- Split out the bit to move ceph cap-getting on readahead into
ceph_init_request()[1].
- Stick in a comment to the netfs inode structs indicating the contiguity
requirements[2].
ver #2)
- Adjust documentation to match.
- Use "#if IS_ENABLED()" in netfs_i_cookie(), not "#ifdef".
- Move the cap check from ceph_readahead() to ceph_init_request() to be
called from netfslib.
- Remove ceph_readahead() and use netfs_readahead() directly instead.

Change the request initialisation function to return an error code so that
the network filesystem can return a failure (ENOMEM, for example).
This will also allow ceph to abort a ->readahead() op if the server refuses
to give it a cap allowing local caching from within the netfslib framework
(errors aren't passed back through ->readahead(), so returning, say,
-ENOBUFS will cause the op to be aborted).

Pass start and len to the rreq allocator. This should ensure that the
fields are set so that ->init_request() can use them.
Also add a parameter to indicates the origin of the request. Ceph can use
this to tell whether to get caps.
Changes
=======
ver #3)
- Change the author to me as Jeff feels that most of the patch is my
changes now.
ver #2)
- Show the request origin in the netfs_rreq tracepoint.

netfs has a number of lists of symbols for use in tracing, listed in an
enum and then listed again in a symbol->string mapping for use with
__print_symbolic(). This is, however, redundant.
Instead, use the symbol->string mapping list to also generate the enum
where the enum is in the same file.

The rxrpc_call struct has a timer used to handle various timed events
relating to a call. This timer can get started from the packet input
routines that are run in softirq mode with just the RCU read lock held.
Unfortunately, because only the RCU read lock is held - and neither ref or
other lock is taken - the call can start getting destroyed at the same time
a packet comes in addressed to that call. This causes the timer - which
was already stopped - to get restarted. Later, the timer dispatch code may
then oops if the timer got deallocated first.
Fix this by trying to take a ref on the rxrpc_call struct and, if
successful, passing that ref along to the timer. If the timer was already
running, the ref is discarded.
The timer completion routine can then pass the ref along to the call's work
item when it queues it. If the timer or work item where already
queued/running, the extra ref is discarded.

Use rethook for kretprobe function return hooking if the arch sets
CONFIG_HAVE_RETHOOK=y. In this case, CONFIG_KRETPROBE_ON_RETHOOK is
set to 'y' automatically, and the kretprobe internal data fields
switches to use rethook. If not, it continues to use kretprobe
specific function return hooks.

Pull remoteproc updates from Bjorn Andersson:
"In the remoteproc core, it's now possible to mark the sysfs attributes
read only on a per-instance basis, which is then used by the TI wkup
M3 driver.
Also, the rproc_shutdown() interface propagates errors to the caller
and an array underflow is fixed in the debugfs interface. The
rproc_da_to_va() API is moved to the public API to allow e.g. child
rpmsg devices to acquire pointers to memory shared with the remote
processor.
The TI K3 R5F and DSP drivers gains support for attaching to instances
already started by the bootloader, aka IPC-only mode.
The Mediatek remoteproc driver gains support for the MT8186 SCP. The
driver's probe function is reordered and moved to use the devres
version of rproc_alloc() to save a few gotos. The driver's probe
function is also transitioned to use dev_err_probe() to provide better
debug support.
Support for the Qualcomm SC7280 Wireless Subsystem (WPSS) is
introduced. The Hexagon based remoteproc drivers gains support for
voting for interconnect bandwidth during launch of the remote
processor. The modem subsystem (MSS) driver gains support for probing
the BAM-DMUX driver, which provides the network interface towards the
modem on a set of older Qualcomm platforms. In addition a number a bug
fixes are introduces in the Qualcomm drivers.
Lastly Qualcomm ADSP DeviceTree binding is converted to YAML format,
to allow validation of DeviceTree source files"

The rproc_shutdown() function is currently not returning any
error code, and any failures within rproc_stop() are not passed
back to the users. Change the signature to return a success value
back to the callers.
The remoteproc sysfs and cdev interfaces are also updated to
return back this status to userspace.

The rproc_da_to_va() API is an exported function, so move its
declaration from the remoteproc local remoteproc_internal.h
to the public remoteproc.h file.
This will allow drivers outside of the remoteproc folder to be
able to use this API.

The remoteproc framework provides sysfs interfaces for changing
the firmware name and for starting/stopping a remote processor
through the sysfs files 'state' and 'firmware'. The 'coredump'
file is used to set the coredump configuration. The 'recovery'
sysfs file can also be used similarly to control the error recovery
state machine of a remoteproc. These interfaces are currently
allowed irrespective of how the remoteprocs were booted (like
remoteproc self auto-boot, remoteproc client-driven boot etc).
These interfaces can adversely affect a remoteproc and its clients
especially when a remoteproc is being controlled by a remoteproc
client driver(s). Also, not all remoteproc drivers may want to
support the sysfs interfaces by default.
Add support to make the remoteproc sysfs files read only by
introducing a state flag 'sysfs_read_only' that the individual
remoteproc drivers can set based on their usage needs. The default
behavior is to allow the sysfs operations as before.
Implement attribute_group->is_visible() to make the sysfs
entries read only when 'sysfs_read_only' flag is set.

Pull rpmsg updates from Bjorn Andersson:
"The major part of the rpmsg changes for v5.18 relates to improvements
in the rpmsg char driver, which now allow automatically attaching to
rpmsg channels as well as initiating new communication channels from
the Linux side.
The SMD driver is moved to arch_initcall with the purpose of
registering root clocks earlier during boot.
Also in the SMD driver, a workaround for the resource power management
(RPM) channel is introduced to resolve an issue where both the RPM and
Linux side waits for the other to close the communication established
by the bootloader - this unblocks support for clocks and regulators on
some older Qualcomm platforms"

Allow the user space application to create and release an rpmsg device
by adding RPMSG_CREATE_DEV_IOCTL and RPMSG_RELEASE_DEV_IOCTL ioctrls to
the /dev/rpmsg_ctrl interface
The RPMSG_CREATE_DEV_IOCTL Ioctl can be used to instantiate a local rpmsg
device.
Depending on the back-end implementation, the associated rpmsg driver is
probed and a NS announcement can be sent to the remote processor.
The RPMSG_RELEASE_DEV_IOCTL allows the user application to release a
rpmsg device created either by the remote processor or with the
RPMSG_CREATE_DEV_IOCTL call.
Depending on the back-end implementation, the associated rpmsg driver is
removed and a NS destroy rpmsg can be sent to the remote processor.

I2C board info is only required during adapter setup so there is no
requirement to keeping a pointer to it once running. To support dynamic
device addition we can't rely on board info - user-space creation
through sysfs won't have a boardinfo.

Pull clk updates from Stephen Boyd:
"There's one large change in the core clk framework here. We change how
clk_set_rate_range() works so that the frequency is re-evaulated each
time the rate is changed. Previously we wouldn't let clk providers see
a rate that was different if it was still within the range, which
could be bad for power if the clk could run slower when a range
expands. Now the clk provider can decide to do something differently
when the constraints change. This broke Nvidia's clk driver so we had
to wait for the fix for that to bake a little more in -next.
The rate range patch series also introduced a kunit suite for the clk
framework that we're going to extend in the next release. It already
made it easy to find corner cases in the rate range patches so I'm
excited to see it cover more clk code and increase our confidence in
core framework patches in the future. I also added a kunit test for
the basic clk gate code and that work will continue to cover more
basic clk types: muxes, dividers, etc.
Beyond the core code we have the usual set of clk driver updates and
additions. Qualcomm again dominates the diffstat here with lots more
SoCs being supported and i.MX follows afer that with a similar number
of SoCs gaining clk drivers. Beyond those large additions there's
drivers being modernized to use clk_parent_data so we can move away
from global string names for all the clks in an SoC. Finally there's
lots of little fixes all over the clk drivers for typos, warnings, and
missing clks that aren't critical and get batched up waiting for the
next merge window to open. Nothing super big stands out in the driver
pile. Full details are below.

Define CE5_SRC is not used so it's OK to change and we align it to
the QSDK naming.
