This function will be needed by the next patch where the driver
calculates the BW based on driver specific parameters, so export it.
At the same time sanitize the function params, passing the more natural
link rate instead of the encoding of the same rate.

Simplify the frontbuffer unpin by removing the lock requirement. The LRU
bumping was primarily to protect the GTT from being evicted and from
frontbuffers being eagerly shrunk. Now we protect frontbuffers from the
shrinker, and we avoid accidentally evicting from the GTT, so the
benefit from bumping LRU is no more, and we can save more time by not.

If we enable_breadcrumbs for a request while that request is being
removed from HW; we may see that the request is active as we take the
ce->signal_lock and proceed to attach the request to ce->signals.
However, during unsubmission after marking the request as inactive, we
see that the request has not yet been added to ce->signals and so skip
the removal. Pull the check during cancel_breadcrumbs under the same
spinlock as enabling so that we the two tests are consistent in
enable/cancel.
Otherwise, we may insert a request onto ce->signals that we expect should
not be there:
intel_context_remove_breadcrumbs:488 GEM_BUG_ON(!__i915_request_is_complete(rq))
While updating, we can note that we are always called with
irqs-disabled, due to the engine->active.lock being held at the single
caller, and so remove the irqsave/restore making it symmetric to
enable_breadcrumbs.

Prevent the ICL HDR plane pipeline from performing YUV color range
correction twice when the input is in limited range. This is done by
removing the limited-range code from icl_program_input_csc().
Before this patch the following could happen: user space gives us a YUV
buffer in limited range; per the pipeline in [1], the plane would first
go through a "YUV Range correct" stage that expands the range; the plane
would then go through the "Input CSC" stage which would also expand the
range because icl_program_input_csc() would use a matrix and an offset
that assume limited-range input; this would ultimately cause dark and
light colors to appear darker and lighter than they should respectively.
This is an issue because if a buffer switches between being scanned out
and being composited with the GPU, the user will see a color difference.
If this switching happens quickly and frequently, the user will perceive
this as a flickering.

In thunderbolt mode the PHY is owned by the thunderbolt controller.
We are not supposed to touch it. So skip the vswing programming
as well (we already skipped the other steps not applicable to TBT).
Touching this stuff could supposedly interfere with the PHY
programming done by the thunderbolt controller.

[Why]
Currently we discard the current context and recreate it. The current
context is what is applied to the HW so we should be re-using this
rather than creating a new context.
Recreating the context can lead to mismatch between new context and the
current context
For example: gsl groups get changed when we create a new context this
can cause issues in a multi display config (with flip immediate) because
we don't align the existing gsl groups in the new and current context.
If we reuse the current context the gsl group assignment stays the same.
[How]
Instead of discarding the current context, we instead just copy the
current state and add/remove planes and streams.

Some newer APUs can scanout directly from GTT, that saves us from
allocating another bounce buffer in VRAM and enables freesync in such
configurations.
Without this patch creating a framebuffer from the imported BO will
fail and userspace will fall back to a copy.

In drm_gem_object_free, it will call funcs of drm buffer obj. So
kfd_alloc should use amdgpu_gem_object_create instead of
amdgpu_bo_create to initialize the funcs as amdgpu_gem_object_funcs.

drm hotplug handling code (drm_client_dev_hotplug()) can wait on mutex,
thus delaying further lt9611uxc IRQ events processing. It was observed
occasionally during bootups, when drm_client_modeset_probe() was waiting
for EDID ready event, which was delayed because IRQ handler was stuck
trying to deliver hotplug event.
Move hotplug notifications from IRQ handler to separate work to be able
to process IRQ events without delays.

Since I wrote the below patch if you run a debug kernel you can a
dma debug warning like:
nouveau 0000:1f:00.0: DMA-API: device driver tries to sync DMA memory it has not allocated [device address=0x000000016e012000] [size=4096 bytes]
The old nouveau code wasn't consolidate the pages like the ttm code,
but the dma-debug expects the sync code to give it the same base/range
pairs as the allocator.
Fix the nouveau sync code to consolidate pages before calling the
sync code.

With the new 2 step scanning process, which defers instantiating some
ACPI-devices based on their _DEP to the second step, the following may
happen:
1. During the first acpi_walk_namespace(acpi_bus_check_add) call
acpi_scan_check_dep() gets called on the Battery ACPI dev handle and
adds one or more deps for this handle to the acpi_dep_list
2. During the first acpi_bus_attach() call one or more of the suppliers of
these deps get their driver attached and
acpi_walk_dep_device_list(supplier_handle) gets called.
At this point acpi_bus_get_device(dep->consumer) get called,
but since the battery has DEPs it has not been instantiated during the
first acpi_walk_namespace(acpi_bus_check_add), so the
acpi_bus_get_device(dep->consumer) call fails.
Before this commit, acpi_walk_dep_device_list() would now continue
*without* removing the acpi_dep_data entry for this supplier,consumer
pair from the acpi_dep_list.
3. During the second acpi_walk_namespace(acpi_bus_check_add) call
an acpi_device gets instantiated for the battery and
acpi_scan_dep_init() gets called to initialize its dep_unmet val.
Before this commit, the dep_unmet count would include DEPs for
suppliers for which acpi_walk_dep_device_list(supplier_handle)
has already been called, so it will never become 0 and the
ACPI battery driver will never get attached / bind.
Fix the ACPI battery driver never binding in this scenario by making
acpi_walk_dep_device_list() always remove matching acpi_dep_data
entries independent of the acpi_bus_get_device(dep->consumer) call
succeeding or not.

The DE2 display engine hardware takes physical addresses that do not
need PHYS_BASE subtracted. As a result, they should not be present
on the mbus driver match list. Remove them.
This was tested on the A83T, along with the patch allowing the DMA
range map to be non-NULL and restores a working display.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes
Fixes for omaps for v5.11-rc cycle
The recent changes to switch SoCs to boot with ti-sysc interconnect
target module driver and genpd caused few regressions:
- The omap_prm reset driver needs to clear any reset bits deasserted by
the bootloader or kexec boot for the three reset bit cases. Otherwise
we can have an oops with accelerators starting to boot with potentially
unconfigured MMU for example
- Custom kernel configs are not automatically selecting simple-pm-bus
driver that we now need to probe interconnects so we need to select it
always
- We are not passing legacy platform data in auxdata with simple-pm-bus
like we do for simple-bus. We need to pass auxdata to simple-pm-bus so
it can pass it to of_platform_populate()
Then recent RCU changes started causing splats for cpuidle44xx that now
need RCU_NONIDLE added to the calls in several places
And then we have few device specific fixes:
- We need to remove legacy spi-cs-hig for gta04 display to work, and
set the gpio to active low
- Omap1 specific ohci-omap needs to call gpio_free()
- Droid4 needs to use padconf interrupt for the slider as the edge
gpio interrupts may be lost for deeper idle states

After converting am335x to probe devices with simple-pm-bus I noticed
that we are not passing auxdata for of_platform_populate() like we do
with simple-bus.
While device tree using SoCs should no longer need platform data, there
are still quite a few drivers that still need it as can be seen with
git grep OF_DEV_AUXDATA. We want to have simple-pm-bus be usable as a
replacement for simple-bus also for cases where OF_DEV_AUXDATA is still
needed.
Let's fix the issue by passing auxdata as platform data to simple-pm-bus.
That way the SoCs needing this can pass the auxdata with OF_DEV_AUXDATA.
And let's pass the auxdata for omaps to fix the issue for am335x.
As an alternative solution, adding simple-pm-bus handling directly to
drivers/of/platform.c was considered, but we would still need simple-pm-bus
device driver. So passing auxdata as platform data seems like the simplest
solution.

We have rst_map_012 used for various accelerators like dsp, ipu and iva.
For these use cases, we have rstctrl bit 2 control the subsystem module
reset, and have and bits 0 and 1 control the accelerator specific
features.
If the bootloader, or kexec boot, has left any accelerator specific
reset bits deasserted, deasserting bit 2 reset will potentially enable
an accelerator with unconfigured MMU and no firmware. And we may get
spammed with a lot by warnings on boot with "Data Access in User mode
during Functional access", or depending on the accelerator, the system
can also just hang.
This issue can be quite easily reproduced by setting a rst_map_012 type
rstctrl register to 0 or 4 in the bootloader, and booting the system.
Let's just assert all reset bits for rst_map_012 type resets. So far
it looks like the other rstctrl types don't need this. If it turns out
that the other type rstctrl bits also need reset on init, we need to
add an instance specific reset mask for the bits to avoid resetting
unwanted bits.

When set_config changes a line from input to output debounce is
implicitly disabled, as debounce makes no sense for outputs, but the
debounce period is not being cleared and is still reported in the
line info.
So clear the debounce period when the debouncer is stopped in
edge_detector_stop().

Recently userspace has started making more use of SW_TABLET_MODE
(when an input-dev reports this).
Specifically recent GNOME3 versions will:
1. When SW_TABLET_MODE is reported and is reporting 0:
1.1 Disable accelerometer-based screen auto-rotation
1.2 Disable automatically showing the on-screen keyboard when a
text-input field is focussed
2. When SW_TABLET_MODE is reported and is reporting 1:
2.1 Ignore input-events from the builtin keyboard and touchpad
(this is for 360° hinges style 2-in-1s where the keyboard and
touchpads are accessible on the back of the tablet when folded
into tablet-mode)
This means that claiming to support SW_TABLET_MODE when it does not
actually work / reports correct values has bad side-effects.
The check in the hp-wmi code which is used to decide if the input-dev
should claim SW_TABLET_MODE support, only checks if the
HPWMI_HARDWARE_QUERY is supported. It does *not* check if the hardware
actually is capable of reporting SW_TABLET_MODE.
This leads to the hp-wmi input-dev claiming SW_TABLET_MODE support,
while in reality it will always report 0 as SW_TABLET_MODE value.
This has been seen on a "HP ENVY x360 Convertible 15-cp0xxx" and
this likely is the case on a whole lot of other HP models.
This problem causes both auto-rotation and on-screen keyboard
support to not work on affected x360 models.
There is no easy fix for this, but since userspace expects
SW_TABLET_MODE reporting to be reliable when advertised it is
better to not claim/report SW_TABLET_MODE support at all, then
to claim to support it while it does not work.
To avoid the mentioned problems, add a new enable_tablet_mode_sw
module-parameter which defaults to false.
Note I've made this an int using the standard -1=auto, 0=off, 1=on
triplett, with the hope that in the future we can come up with a
better way to detect SW_TABLET_MODE support. ATM the default
auto option just does the same as off.

map_direct_mr() assumed that the number of scatter/gather entries
returned by dma_map_sg_attrs() was equal to the number of segments in
the sgl list. This led to wrong population of the mkey object. Fix this
by properly referring to the returned value.
The hardware expects each MTT entry to contain the DMA address of a
contiguous block of memory of size (1 << mr->log_size) bytes.
dma_map_sg_attrs() can coalesce several sg entries into a single
scatter/gather entry of contiguous DMA range so we need to scan the list
and refer to the size of each s/g entry.
In addition, get rid of fill_sg() which effect is overwritten by
populate_mtts().

mlx5 fixes 2021-02-01
Please note the first patch in this series
("Fix function calculation for page trees") is fixing a regression
due to previous fix in net which you didn't include in your previous
rc pr. So I hope this series will make it into your next rc pr,
so mlx5 won't be broken in the next rc.
