ASoC: Intel: catpt: Code cleanup and renames
Cezary Rojewski <cezary.rojewski@intel.com> says:

Direct follow up to the cleanup from June [1] and fixes from May [2].
Patches 4/8 and 5/8 is what I actually started with, several years ago
when doing first attempts in addressing the long-standing problem [3].
With these, it is easy for a developer to move between the driver and
the firmware repository.  A clear example of why naming is imporant.

Patches 2-8 carry no functional impact.
Patch 1/8 slightly alters the suspend procedure as explained in its
commit message.  From practical perspective though, 1/8 too has no real
impact on the functional flow.

Changes found here reduce the code complexity slightly and rename a
bunch of functions and variables.

ASoC: Intel: catpt: Wrap the store firmware-context procedure
All store/restore firmware operations are located in the loader.c file.
All except the "store firmware context" procedure which is manually
called during the runtime suspend, device.c file.

Adding a wrapper alters functional flow slightly - DMA channel is
requested after the DXSTATE IPC rather than before it but this has no
real impact on the procedure.

At the same time, such approach limits number of symbols exposed in the
core.h file and improves code cohesiveness: all catpt_dma_xxx()
definitions in dsp.c, all their usages in loader.c.

20697ecb29 drm/bridge: ps8640: propagate AUX transfer register errors
ps8640_aux_transfer_msg() programs the AUX address registers, starts the
AUX transfer, waits for SWAUX_SEND to clear, and reads the AUX status
register. Several of those regmap operations have return values, but the
function only checks a stale ret after the status read.

Propagate failures from the address write, transfer start, completion
poll, and status read. This avoids returning a transfer length when the
bridge register transaction or AUX completion wait failed.

d4d2fcb3e3 clk: qcom: gcc-mdm9607: Drop redundant register update during probe
GPLL0 is pretty much guaranteed to be already on (and voted) during boot,
since it's used by the CPU and also various other components such as UART.
We also vote for this bit in the actual GPLL0 definition, which will be set
as soon as any driver in the kernel requires using the GPLL0 clock.

All in all, this makes separately voting for GPLL0 during probe redundant,
especially because the "acpuclock" in the comment is a downstream construct
that does not exist in upstream.

e111ddda09 clk: qcom: gcc-mdm9607: Drop incorrect BIMC PLL and related clocks
The gcc-mdm9607 driver was originally based on gcc-msm8916, but a closer
match nowadays is gcc-msm8909. Looking at the differences between
gcc-mdm9607 and gcc-msm8909, there is quite some confusion around the
definitions for the BIMC PLL.

It turns out the BIMC PLL on MDM9607 is actually an Alpha PLL just like on
MSM8909. We can vote for it using BIT(2), which explains why BIT(3) was
used for GPLL2.

In practice, the BIMC PLL is exclusively controlled by the RPM firmware and
Linux should not touch it. So far, it was defined to model the full clock
hierarchy, but even in read-only mode with CLK_GET_RATE_NOCACHE this is
problematic since the RPM will silently change the clock parents without
notifying Linux about it. The clock framework reads the clock parent only
once during boot, so the resulting rates will still be often wrong.

Follow the example of more recent SoCs and drop the BIMC PLL and all
remaining related clocks to avoid reporting stale status data. This means
we cannot determine the rate of these clocks anymore. This is not a big
problem in practice, since these are NoC-related clocks that are
independently managed through the interconnect subsystem.

17784427df clk: qcom: gcc-mdm9607: Drop incorrect system_noc_bfdcd_clk_src
This clock does not exist on MDM9607. Reading/writing the registers always
results in 0.

Presumably, this definition was mistakenly copied from gcc-msm8916. On
MSM8916, this root clock is used for multimedia subsystems (camera,
display, video). MDM9607 has none of that, so this clock was probably
omitted in the hardware.

There are no users inside gcc-mdm9607, so we can just drop it.

38d06956f6 clk: qcom: gcc-mdm9607: Drop incorrect apss_tcu_clk_src
This clock does not exist on the specified address on MDM9607.
Reading/writing the registers always results in 0 or crashes. The math in
the frequency table is also broken. GPLL2 on MDM9607 runs at 480 MHz, so:

 - F(155000000, P_GPLL2, 6, 0, 0), // 480 MHz/6 = 80 MHz, not 155 MHz
 - F(310000000, P_GPLL2, 3, 0, 0), // 480 MHz/3 = 160 MHz, not 310 MHz

Presumably, this definition was mistakenly copied as-is from gcc-msm8916
(which uses 930 MHz for GPLL2). There are no branch consumers of this root
clock inside gcc-mdm9607 (notably, gcc_apss_tcu_clk has bimc_ddr_clk_src as
parent instead of this clock), so we can just drop it.

It seems like this clock does exist on this SoC on a different address, but
since there is no user and reference code for it, it is still better to
drop it.

some targets have less CFG RAM than the constant implies, while others

valid firmware to be rejected at load time.

Rather than hardcoding a constant, read PROG_RAM_DEPTH from SE_HW_PARAM_2
at runtime to get the actual CFG RAM depth of the hardware instance and
use that as the upper bound for firmware size validation.

e806c63ba5 arm64: dts: qcom: Rename pci@ nodes to pcie@
PCIe hosts/devices commonly use the 'pcie' for their node name to
reflect they're not legacy PCI.

Every couple months someone comes around to clean this up because
people keep introducing new uses of 'pci@'. Seems like it's my turn
now, so do that for RCs and the downstream devices (switches etc.)
defined in board files.

The touchscreen module on Glymur/Mahua CRDs is different from

permanently asserted during resume leaving the device offline and causing

17fcdecb14 rust: driver: remove duplicate ID table
Previously, `IdArray` contains both device ID table and info table so we
keep a separate copy for MODULE_DEVICE_TABLE for hotplug (which needs to be
just the device ID table). With the info being changed to be carried via
pointers, `IdArray` is now layout compatible with raw ID table and hence
there is no longer a need to keep the distinction.

Deduplicate the code, and remove the redundant copy for hotplug purpose by
just giving the `IdArray` instance a proper symbol name.

While at it, also update the macro to use `::core::line!()` instead of just
`line!()`.

0b76335e8f rust: driver: store pointers in DeviceId
The common practice in C drivers is to store pointers into `driver_data`
field of device IDs. The Rust code is however currently storing indices
into the fields and then carry a side table that maps the index to
pointers.

It is much simpler to just have `DeviceId` carry the pointer like C code
does. However, just doing so naively would cause a "pointers cannot be cast
to integers during const eval" error, as kernel_ulong_t does not have
provenance while pointers do, and Rust forbids `expose_provenance` during
consteval.

Work around this limitation by wrapping raw IDs in `MaybeUninit`.
`MaybeUninit` is allowed to host arbitrary bytes with or without
provenance, so we can just then use `unsafe` to store a pointer with
provenance there. This has the same effect as changing the C-side
definition to use `void*` instead of `kernel_ulong_t`, but without actually
changing the C side.

bc0e8faf90 io_uring: preserve task restrictions across exec
Per-task restrictions apply to all rings created by a task. Once
installed, they should not be dropped across exec.

For a task that has used io_uring, the exec cancellation path calls
__io_uring_free(). This frees both the task context and the per-task
restriction, so a ring created after exec is unrestricted.

Split task context cleanup into io_uring_free_tctx(), and use it from
the exec cancellation path. Keep __io_uring_free() for final task
cleanup, where both the context and restriction are released.

The gcc_qupv3_wrap0_s[0-5]_clk_src RCGs feed the QUP serial engines
(UART/I2C/SPI). Since shared RCGs are parked to XO at registration time,
binding the gcc-qcm2290 driver reprograms these clocks away from the
rate configured by the bootloader. For the UART used as the boot console
this drops early console output until the serial driver later
reconfigures the clock.

Switch the QUP wrap0 clock sources over to
clk_rcg2_shared_no_init_park_ops so their frequency is left unchanged at
registration time, keeping the bootloader-configured console working
across the gcc driver probe.

drm/i915/hdmi: Poll for 200 msec for TMDS_Scrambler_Status
HDMI 2.0 section 6.1.3.1 specifies that after enabling
Scrambling_Enable and starting scrambled video transmission, the source
should poll Scrambling_Status until it reads 1 or until a timeout of
200 ms expires.

Add a polling step after enabling the HDMI port to check the scrambling
status when HDMI scrambling is enabled.

On some HDMI 2.0 sinks, omitting this check can result in 4K@60Hz
(594 MHz) failing to come up correctly because the sink has not yet
finished its scrambling setup. In practice, waiting for the scrambling
status here fixes such sinks.

While this synchronous polling is not itself explicitly required for
correct modeset sequencing, HDMI 2.0 section 6.1.3.1 does recommend it
as the way for the source to verify that the TMDS link is functioning
correctly with scrambling enabled.

v3:
 - Add explicit HDMI 2.0 section reference in code comment
 - Clarify commit message around the observed sink fix

v2:
 - Poll TMDS_Scrambler_Status for up to 200 ms instead of using a fixed
   delay
