struct cap11xx_hw_model is supposed to describe the chip capabilities,
however later code changes introduced checks against chip ID.
Introduce new capabilities in cap11xx_hw_model and use them when applying
chip configuration, and remove the enum for chip ID. While at it, rename
no_gain to has_gain to match the rest of the new capabilities.

When one or more axes are inverted, (where min > max), normalize the
data so that min < max and invert the values reported to the input
stack.
This ensures we can continue defining the device correctly in the
device tree while not breaking downstream assumptions that min is
always less than max.

The intel_pch_thermal cooling mechanism currently only provides one of
the following final conclusions:
1. intel_pch_thermal 0000:00:12.0: CPU-PCH is cool [48C]
2. intel_pch_thermal 0000:00:12.0: CPU-PCH is cool [49C] after 30700 ms delay
3. intel_pch_thermal 0000:00:12.0: CPU-PCH is hot [60C] after 60000 ms delay. S0ix might fail
4. intel_pch_thermal 0000:00:12.0: Wakeup event detected, abort cooling
This does not provide sufficient context about what is happening,
especially for case 4.
Add one line log to indicate when PCH overheats and the cooling delay
has started.

Note that the Linux driver model assumes that removing a device cannot

Update the default balance_performance EPP to 64. This gives better
performance and also perf/watt compared to current value of 115.
For example:
Speedometer 2.1
score: +19%
Perf/watt: +5.25%
Webxprt 4 score
score: +12%
Perf/watt: +6.12%
3DMark Wildlife extreme unlimited score
score: +3.2%
Perf/watt: +11.5%
Geekbench6 MT
score: +2.14%
Perf/watt: +0.32%
Also update balance_power EPP default to 179. With this change:
Video Playback power is reduced by 52%
Team video conference power is reduced by 35%
With Power profile daemon now sets balance_power EPP on DC instead of
balance_performance, updating balance_power EPP will help to extend
battery life.

A Rembrandt-based HP thin client is reported to have problems where
the NVME disk isn't present after resume from s2idle.
This is because the NVME disk wasn't put into D3 at suspend, and
that happened because the StorageD3Enable _DSD was missing in the BIOS.
As AMD's architecture requires that the NVME is in D3 for s2idle, adjust
the criteria for force_storage_d3 to match *all* Zen SoCs when the FADT
advertises low power idle support.
This will ensure that any future products with this BIOS deficiency don't
need to be added to the allow list of overrides.

The Elan eKTH5015M touch controller on the X13s requires a 300 ms delay
before sending commands after having deasserted reset during power on.
Switch to the Elan specific binding so that the OS can determine the
required power-on sequence and make sure that the controller is always
detected during boot.
Note that the always-on 1.8 V supply (s10b) is not used by the
controller directly and should not be described.

increased WQ_NAME_LEN from 24 to 32, but forget to increase
WORKER_DESC_LEN, which would cause truncation when setting kworker's
desc from workqueue_struct's name, process_one_work() for example.

Clean up laying violation of setting q->flags EXEC_QUEUE_FLAG_BANNED bit
in GuC backend. Move banned to GuC owned bit and report banned status to
upper layers via reset_status vfunc. This is a slight change in behavior
as reset_status returns true if wedged or killed bits set too, but in
all of these cases submission to queue is no longer allowed.

- Remove unused bit definitions.
- Driver uses BIT(0) for waking/sleeping the domain and since the
registers are masked respective mask bit BIT(16) needs to be set. Use
defines for these bits and use them in domain initialization.
v3
- Use defines within domain_init

Add helper function to implement VMA (user binding) page faults, remove
unnecessary userptr.invalidate_link list del operation, retry on memory
pressure, remove unnecessary xe_vma_userptr_check_repin after rebinding,
remove unnecessary TLB invalidation, and always use vm->lock in write
mode. Changes help facilitate SVM page faults.

At least ASUS Zenbook 14 (2023) and ASUS Zenbook 14 Pro (2023) are affected.
The touchscreen reports a battery status of 0% and jumps to 1% when a
stylus is used.
The device ID was added and the battery ignore quirk was enabled for it.

Instead of reimplementing ext4_match_ci, use the new libfs helper.
It also adds a comment explaining why fname->cf_name.name must be
checked prior to the encryption hash optimization, because that tripped
me before.

generic_ci_match can be used by case-insensitive filesystems to compare
strings under lookup with dirents in a case-insensitive way. This
function is currently reimplemented by each filesystem supporting
casefolding, so this reduces code duplication in filesystem-specific
code.
