The PXA168 has a peculiar setup with the AXI clock enable control for
the SDHC controllers. The bits in the SDH0 register control the AXI
clock enable for both SDH0 and SDH1. Likewise, the bits in the SDH2
register control both SDH2 and SDH3. This is modeled with two new
parentless clocks that control the shared bits.
Previously, SDH0 had to be enabled in order for SDH1 to be used, and
when SDH1 was enabled, unused bits in the SDH1 register were being
controlled. This fixes those issues. A future commit will add support
for these new shared clocks to be enabled by the PXA168 SDHC driver.

Commit 951d48855d ("of: Make of_dma_get_range() work on bus nodes")
relaxed the handling of "dma-ranges" for any leaf node on the assumption
that it would still represent a usage error for the property to be
present on a non-bus leaf node. However there turns out to be a fiddly
case where a bus also represents a DMA-capable device in its own right,
such as a PCIe root complex with an integrated DMA engine on its
platform side. In such cases, "dma-ranges" translation is entirely valid
for devices discovered behind the bus, but should not be erroneously
applied to the bus controller device itself which operates in its
parent's address space. Fix this by restoring the previous behaviour for
the specific case where a device is configured via its own OF node,
since it is logical to assume that a device should never represent its
own parent bus.

As an integrated GPU, MTL does not have local memory and HAS_LMEM()
returns false. However the platform's stolen memory is presented via
BAR2 (i.e., the BAR we traditionally consider to be the GMADR on IGFX)
and should be managed by the driver the same way that local memory is
on dgpu platforms (which includes setting the "lmem" bit on page table
entries). We use the term "local stolen memory" to refer to this
model.
The major difference from the traditional BAR2 (GMADR) is that
the stolen area is mapped via the BAR2 while in the former BAR2 is an
aperture into the GTT VA through which access are made into stolen area.
BSPEC: 53098, 63830
v2:
1. dropped is_dsm_invalid, updated valid_stolen_size check from Lucas

2. --alltests used allyesconfig along with a curated list of options to

Because KUnit test execution is not a guarantee with the kunit.enable
parameter we want to be careful to only taint the kernel when actual
tests run. Calling module_info(test, "Y") for every KUnit module
automatically causes the kernel to be tainted upon module load. Therefore,
we're removing this call and relying on the KUnit framework to taint the
kernel or not.

With

you get the raw output from the kernel, e.g. something like

> # Subtest: time_test_cases
> 1..1
> ok 1 - time64_to_tm_test_date_range
> ok 1 - time_test_cases
But --raw_output=kunit or equivalently --raw_output, you get

> # Subtest: time_test_cases
> 1..1
> ok 1 - time64_to_tm_test_date_range
> ok 1 - time_test_cases
It looks less readable in my opinion, and it also isn't "raw output."
This is due to sharing code with kunit_parser.py, which wants to strip
leading whitespace since it uses anchored regexes.
We could update the kunit_parser.py code to tolerate leaading spaces,
but this patch takes the easier way out and adds a bool flag.

On one of the Chrome system, if we define more than 12 trip points,
probe for thermal sensor fails with
"int3403 thermal: probe of INTC1046:03 failed with error -22"
and throws an error as
"thermal_sys: Error: Incorrect number of thermal trips".
The thermal_zone_device_register() interface needs maximum
number of trip points supported in a zone as an argument.
This number can't exceed THERMAL_MAX_TRIPS, which is currently
set to 12. To address this issue, THERMAL_MAX_TRIPS value
has to be increased.
This interface also has an argument to specify a mask of trips
which are writable. This mask is defined as an int.
This mask sets the ceiling for increasing maximum number of
supported trips. With the current implementation, maximum number
of trips can be supported is 31.
Also, THERMAL_MAX_TRIPS macro is used in one place only.
So, remove THERMAL_MAX_TRIPS macro and compare num_trips
directly with using a macro BITS_PER_TYPE(int)-1.

Kalle Valo says:
====================
wireless-next patches for v6.1
Few stack changes and lots of driver changes in this round. brcmfmac
has more activity as usual and it gets new hardware support. ath11k
improves WCN6750 support and also other smaller features. And of
course changes all over.
Note: in early September wireless tree was merged to wireless-next to
avoid some conflicts with mac80211 patches, this shouldn't cause any
problems but wanted to mention anyway.
Major changes:
mac80211
- refactoring and preparation for Wi-Fi 7 Multi-Link Operation (MLO)
feature continues
brcmfmac
- support CYW43439 SDIO chipset
- support BCM4378 on Apple platforms
- support CYW89459 PCIe chipset
rtw89
- more work to get rtw8852c supported
- P2P support
- support for enabling and disabling MSDU aggregation via nl80211
mt76
- tx status reporting improvements
ath11k
- cold boot calibration support on WCN6750
- Target Wake Time (TWT) debugfs support for STA interface
- support to connect to a non-transmit MBSSID AP profile
- enable remain-on-channel support on WCN6750
- implement SRAM dump debugfs interface
- enable threaded NAPI on all hardware
- WoW support for WCN6750
- support to provide transmit power from firmware via nl80211
- support to get power save duration for each client
- spectral scan support for 160 MHz
wcn36xx
- add SNR from a received frame as a source of system entropy

DOWNSPREAD_CTRL (0x107) shall be cleared to 0 upon power-on reset or an
upstream device disconnect. This patch will enforce this rule by always
cleared DOWNSPREAD_CTRL register to 0 before start link training. At rare
case that DP MSA timing parameters may be mis-interpreted by the sink
which causes audio sampling rate be calculated wrongly and cause audio
did not work at sink if DOWNSPREAD_CTRL register is not cleared to 0.
Changes in v2:
1) fix spelling at commit text
2) merge ssc variable into encoding[0]
Changes in v3:
-- correct spelling of DOWNSPREAD_CTRL
-- replace err with len of ssize_t
Changes in v4:
-- split into 2 patches

Device-managed resources allocated post component bind must be tied to
the lifetime of the aggregate DRM device or they will not necessarily be
released when binding of the aggregate device is deferred.
This is specifically true for the HDMI IRQ, which will otherwise remain
requested so that the next bind attempt fails when requesting the IRQ a
second time.
Fix this by tying the device-managed lifetime of the HDMI IRQ to the DRM
device so that it is released when bind fails.

Device-managed resources allocated post component bind must be tied to
the lifetime of the aggregate DRM device or they will not necessarily be
released when binding of the aggregate device is deferred.
This can lead resource leaks or failure to bind the aggregate device
when binding is later retried and a second attempt to allocate the
resources is made.
For the DP bridges, previously allocated bridges will leak on probe
deferral.
Fix this by amending the DP parser interface and tying the lifetime of
the bridge device to the DRM device rather than DP platform device.

This can lead resource leaks or failure to bind the aggregate device

For the DP aux-bus, an attempt to populate the bus a second time will
simply fail ("DP AUX EP device already populated").
Fix this by tying the lifetime of the EP device to the DRM device rather
than DP controller platform device.

Since commit c3bf8e21b3 ("drm/msm/dp: Add eDP support via aux_bus")
this can happen when the aux-bus panel driver has not yet been loaded so
that probe is deferred.
Fix this by tying the device-managed lifetime of the DP IRQ to the DRM
device so that it is released when bind fails.
