Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:
The avs-driver continues to be utilized on more recent Intel machines.
As TGL-based (cAVS 2.5) e.g.: RPL, inherit most of the functionality
from previous platforms:
SKL <- APL <- CNL <- ICL <- TGL
rather than putting everything into a single file, the platform-specific
bits are split into cnl/icl/tgl.c files instead. Makes the division clear
and code easier to maintain.
Layout of the patchset:
First are two changes combined together address the sound-clipping
problem, present when only one stream is running - specifically one
CAPTURE stream.
Follow up is naming-scheme adjustment for some of the existing functions
what improves code incohesiveness. As existing IPC/IRQ code operates
solely on cAVS 1.5 architecture, it needs no abstraction. The situation
changes when newer platforms come into the picture. Thus the next two
patches abstract the existing IPC/IRQ handlers so that majority of the
common code can be re-used.
The ICCMAX change stands out a bit - the AudioDSP firmware loading
procedure differs on ICL-based platforms (and onwards) and having a
separate commit makes the situation clear to the developers who are
going to support the solution from LTS perspective. For that reason
I decided not to merge it into the commit introducing the icl.c file.

When updating the affinity of a VPE, the VMOVP command is currently skipped
if the two CPUs are part of the same VPE affinity.
But this is wrong, as the doorbell corresponding to this VPE is still
delivered on the 'old' CPU, which screws up the balancing. Furthermore,
offlining that 'old' CPU results in doorbell interrupts generated for this
VPE being discarded.
The harsh reality is that VMOVP cannot be elided when a set_affinity()
request occurs. It needs to be obeyed, and if an optimisation is to be
made, it is at the point where the affinity change request is made (such as
in KVM).
Drop the VMOVP elision altogether, and only use the vpe_table_mask
to try and stay within the same ITS affinity group if at all possible.

While refactoring the way the ITSs are probed, the handling of quirks
applicable to ACPI-based platforms was lost. As a result, systems such as
HIP07 lose their GICv4 functionnality, and some other may even fail to
boot, unless they are configured to boot with DT.
Move the enabling of quirks into its_probe_one(), making it common to all
firmware implementations.

Although the GICv3 code base has gained some handling of systems failing to
handle the shareability attributes, the GICv4 side of things has been
firmly ignored.
This is unfortunate, as the new recent addition of the "dma-noncoherent" is
supposed to apply to all of the GICR tables, and not just the ones that are
common to v3 and v4.
Add some checks to handle the VPROPBASE/VPENDBASE shareability and
cacheability attributes in the same way we deal with the other GICR_BASE
registers, wrapping the flag check in a helper for improved readability.
Note that this has been found by inspection only, as I don't have access to
HW that suffers from this particular issue.

eiointc_domain_alloc() uses struct eiointc, which is not defined, for a
pointer. Older compilers treat that as a forward declaration and due to
assignment of a void pointer there is no warning emitted. As the variable
is then handed in as a void pointer argument to irq_domain_set_info() the
code is functional.
Use struct eiointc_priv instead.

It was observed on Broadcom devices that use GIC v3 architecture L1
interrupt controllers as the parent of brcmstb-l2 interrupt controllers
that the deactivation of the parent interrupt could happen before the
brcmstb-l2 deasserted its output. This would lead the GIC to reactivate the
interrupt only to find that no L2 interrupt was pending. The result was a
spurious interrupt invoking handle_bad_irq() with its associated
messaging. While this did not create a functional problem it is a waste of
cycles.
The hazard exists because the memory mapped bus writes to the brcmstb-l2
registers are buffered and the GIC v3 architecture uses a very efficient
system register write to deactivate the interrupt.
Add a write memory barrier prior to invoking chained_irq_exit() to
introduce a dsb(st) on those systems to ensure the system register write
cannot be executed until the memory mapped writes are visible to the
system.

According to the Intel datasheets, software must reset the block
buffer index twice for block process call transactions: once before
writing the outgoing data to the buffer, and once again before
reading the incoming data from the buffer.
The driver is currently missing the second reset, causing the wrong
portion of the block buffer to be read.

For i2c read operation in GSI mode, we are getting timeout
due to malformed TRE basically incorrect TRE sequence
in gpi(drivers/dma/qcom/gpi.c) driver.
I2C driver has geni_i2c_gpi(I2C_WRITE) function which generates GO TRE and
geni_i2c_gpi(I2C_READ)generates DMA TRE. Hence to generate GO TRE before
DMA TRE, we should move geni_i2c_gpi(I2C_WRITE) before
geni_i2c_gpi(I2C_READ) inside the I2C GSI mode transfer function
i.e. geni_i2c_gpi_xfer().
TRE stands for Transfer Ring Element - which is basically an element with
size of 4 words. It contains all information like slave address,
clk divider, dma address value data size etc).
Mainly we have 3 TREs(Config, GO and DMA tre).
- CONFIG TRE : consists of internal register configuration which is
required before start of the transfer.
- DMA TRE : contains DDR/Memory address, called as DMA descriptor.
- GO TRE : contains Transfer directions, slave ID, Delay flags, Length
of the transfer.
I2c driver calls GPI driver API to config each TRE depending on the
protocol.
For read operation tre sequence will be as below which is not aligned
to hardware programming guide.
- CONFIG tre
- DMA tre
- GO tre
As per Qualcomm's internal Hardware Programming Guide, we should configure
TREs in below sequence for any RX only transfer.
- CONFIG tre
- GO tre
- DMA tre

The links in a cycle are not all logged in a consistent manner or not
logged at all. Make them consistent by adding a "cycle:" string and log all
the link in the cycles (even the child ==> parent dependency) so that it's
easier to debug cycle detection code. Also, mark the start and end of a
cycle so it's easy to tell when multiple cycles are logged back to back.

fw_devlink can detect most overlapping/intersecting cycles. However it was
missing a few corner cases because of an incorrect optimization logic that
tries to avoid repeating cycle detection for devices that are already
marked as part of a cycle.
Here's an example provided by Xu Yang (edited for clarity):
usb
+-----+
tcpc | |
+-----+ | +--|
| |----------->|EP|
|--+ | | +--|
|EP|<-----------| |
|--+ | | B |
| | +-----+
| A | |
+-----+ |
^ +-----+ |
| | | |
+-----| C |<--+
| |
+-----+
usb-phy
Node A (tcpc) will be populated as device 1-0050.
Node B (usb) will be populated as device 38100000.usb.
Node C (usb-phy) will be populated as device 381f0040.usb-phy.
The description below uses the notation:
consumer --> supplier
child ==> parent
1. Node C is populated as device C. No cycles detected because cycle
detection is only run when a fwnode link is converted to a device link.
2. Node B is populated as device B. As we convert B --> C into a device
link we run cycle detection and find and mark the device link/fwnode
link cycle:
C--> A --> B.EP ==> B --> C
3. Node A is populated as device A. As we convert C --> A into a device
link, we see it's already part of a cycle (from step 2) and don't run
cycle detection. Thus we miss detecting the cycle:
A --> B.EP ==> B --> A.EP ==> A
Looking at it another way, A depends on B in one way:
A --> B.EP ==> B
But B depends on A in two ways and we only detect the first:
B --> C --> A
B --> A.EP ==> A
To detect both of these, we remove the incorrect optimization attempt in
step 3 and run cycle detection even if the fwnode link from which the
device link is being created has already been marked as part of a cycle.

device_link_flag_is_sync_state_only() correctly returns true on the flags
of an existing device link that only implements sync_state() functionality.
However, it incorrectly and confusingly returns false if it's called with
DL_FLAG_SYNC_STATE_ONLY.
This bug doesn't manifest in any of the existing calls to this function,
but fix this confusing behavior to avoid future bugs.

Creating sysfs files for all Cells caused a boot failure for linux-6.8-rc1 on
Apple M1, which (in downstream dts files) has multiple nvmem cells that use the
same byte address. This causes the device probe to fail with

different bits of the same address. Avoid the issue by changing the file name
to include the first bit number.

IIO: 1st set of fixes for the 6.8 cycle
Usual mixed bag of issues introduced this cycle and fixes for long term
issues that have been identified recently + one case where I messed up
a merge resolution and dropped the build file changes.
Most important is the userspace ABI fix for the iio_modifier enum
where we accidentally added new entries in the middle rather than at
the end.
IIO Core
- Close a memory leak in an error path.
- Move LIGHT_UVA and LIGHT_UVB definitions to end of the iio_modifier
enum to avoid breaking older userspace. (not yet in a released kernel
thankfully).
adi,adis
- Fix a DMA buffer alignment issue that was missing in series that fixed
these across IIO.
adi,ad-sigma-delta
- Fix a DMA buffer alignment issue that was missing in series that fixed
these across IIO.
adi,ad4130
- Zero init remaining fields of clock init data.
- Only set GPIO control bits on pins that aren't in use for anything else.
adi,ad5933
- Fix an old bug due to type mismatch. This is a rare device so good to
get some new test coverage.
adi,ad7091r
- Use right variable for an error return code.
bosch,bma400
- Add missing CONFIG_REGMAP_I2C dependency.
bosch,bmp280:
- Add missing bmp085 ID to the SPI table to avoid mismatch with the
of_device_id table.
hid-sensors:
- Avoid returning an error for timestamp read back that succeeds.
pni,rm3100
- Check value read from RM31000_REG_TMRC register is valid before using
it. Hardening to avoid a real world issue seen on some faulty hardware.
st,st-sensors
- Fix a DMA buffer alignment issue that was missing in series that fixed
these across IIO.
ti,hdc3020
- Add missing Kconfig and Makefile entrees accidentally dropped when patches
were applied.
- Fix wrong temperature offset (negated)

Currently, GPIO_CTRL bits are set even if the pins are used for
measurements.
GPIO_CTRL bits should only be set if the pin is not used for
other functionality.
Fix this by only setting the GPIO_CTRL bits if the pin has no
other function.

The clk_init_data struct does not have all its members
initialized, causing issues when trying to expose the internal
clock on the CLK pin.
Fix this by zero-initializing the clk_init_data struct.

When als_capture_sample() is called with usage ID
HID_USAGE_SENSOR_TIME_TIMESTAMP, return 0. The HID sensor core ignores
the return value for capture_sample() callback, so return value doesn't
make difference. But correct the return value to return success instead
of -EINVAL.

Commit 4c3577db3e4f ("Staging: iio: impedance-analyzer: Fix sparse
warning") fixed a compiler warning, but introduced a bug that resulted
in one of the two 16 bit IIO channels always being zero (when both are
enabled).
This is because int is 32 bits wide on most architectures and in the
case of a little-endian machine the two most significant bytes would
occupy the buffer for the second channel as 'val' is being passed as a
void pointer to 'iio_push_to_buffers()'.
Fix by defining 'val' as u16. Tested working on ARM64.

The temperature offset should be negative according to the datasheet.
Adding a minus to the existing offset results in correct temperature

caused by out of bound access of array rm3100_samp_rates (because of
underlying hardware failures). Add boundary check to prevent out of
bound access.

interconnect fixes for v6.8-rc
These are tiny fixes for reported issues in driver code for a few
platforms. One of them sorts out a hang issue, the other improves
the power consumption and the rest are fixing some bitmasks to make
sure the hardware does thing right.

Emil reports:
After updating Linux on an i.MX28 board, serial communication over
AUART broke. When I TX from the board and measure on the TX pin, it
seems like the HW fifo is not emptied before the transmission is
stopped.
MXS performs weird things with stop_tx(). The driver makes it
conditional on uart_tx_stopped().
So the driver needs special handling. Pass the brand new UART_TX_NOSTOP
to uart_port_tx_flags() and handle the stop on its own.

This reverts commit 398aa9a7e77cf23c2a6f882ddd3dcd96f21771dc.
The update to the gadget API to support EBC feature is incomplete. It's
missing at least the following:
* New usage documentation
* Gadget capability check
* Condition for the user to check how many and which endpoints can be
used as "fifo_mode"
* Description of how it can affect completed request (e.g. dwc3 won't
update TRB on completion -- ie. how it can affect request's actual
length report)
Let's revert this until it's ready.

The atomisp driver emulates a standard v4l2 device, which also works
for non media-controller aware applications.
Part of this requires making try_fmt calls on the sensor when
a normal v4l2 app is making try_fmt calls on the /dev/video# mode.
With the recent v4l2_subdev_state handling changes in 6.8 this no longer
works, fixing this requires 2 changes:
1. The atomisp code was using its own internal v4l2_subdev_pad_config
for this. Replace the internal v4l2_subdev_pad_config with allocating
a full v4l2_subdev_state for storing the full try_fmt state.
2. The paths actually setting the fmt or crop selection now need to be
passed the v4l2_subdev's active state, so that sensor drivers which
are using the v4l2_subdev's active state to store their state keep
working.
