RISC-V Devicetrees for v6.19
MAINTAINERS:
There's some re-jigging of things to reduce duplication, by moving me
into the StarFive entry and my tree into the Microchip one. The
other platforms that I look after (SiFive and Canaan) are marked as Odd
Fixes to better represent their status. Nothing functionally changes.
Microchip:
Add adc and mmc nodes for the Beagle-V Fire.
SiFive:
Add pwm fans to the unmatched board.
StarFive:
Add the Orange PI RV board, another VisionFive 2 derived SBC. This
required moving a mmc related nodes out of the common file, into
<board>.dts. Yet more things moved out of the common file when the
VisionFive 2 Lite boards were added, which use the JH7110S SoC instead of
the JH7110. The difference here between SoCs is just temperature and
frequency ranges, but the boards differ enough that the pool of common
nodes decreases a little further. There's an eMMC and an SD variant
here, that are different SKUs, bringing the total new StarFive boards to
three.

The base address of JPEG decoder core 1 should start at 0x10000, and
have a size of 0x10000, i.e. it is right after core 0.
Instead the core has the same base address as core 0, and with a crazy
large size. This looks like a mixup of address and size cells when the
ranges were converted.
This causes the kernel to fail to register the second core due to sysfs
name conflicts:
sysfs: cannot create duplicate filename '/devices/platform/soc/soc:jpeg-decoder@1a040000/1a040000.jpgdec'
Fix up the address range.

Currently the sof_sdw machine driver assumes that all devices involved
in the sound card are connected through a DAI link. However for SDCA
devices we still want the HID (Human Interface Device, used for jack
buttons) to be part of the sound card, but it contains no DAI links.
Add support into the machine driver to specify a list of auxiliary
devices to merged into the card.

The assumption so far is that all the DAI links for a given audio part
would be on the same device. However, as SDCA implements each audio
function on a separate auxiliary driver this will no longer be true.
This means it is necessary to add additional codec_conf structures to
get the prefix for an audio part to apply to all the auxiliary drivers
that make up that part.

There have been some complaints around the UCM files for SDCA
devices that the control system is quite hard to follow. This is
definitely true without the specification handy the naming can be
a little cryptic. However, as most of the information is parsed
from DisCo there are some limits to what the driver can safely do
to improve this.
However, one area that can be improved is the non-streaming
input/output terminals. These have a field (enum sdca_terminal_type)
that describes the usage of that terminal. These types can be
appended to the entity name to give the users a better clue as
to the purpose. For example "OT 43", would now become "OT 43
Headphone". This would follow through into the jack controls which
would change from "OT 43 Jack" to "OT 43 Headphone Jack", making the
purpose much more obvious to the user.
This provides slightly more readable controls without relying on
implicit knowledge that individual parts might not conform to.

Currently mute controls will be called "FU xx Mute Switch" (note
the switch is added programmatically outside the coverage of this
patch) and the accompanying volume control would be called "FU xx
Channel Volume". These names are taken from the SDCA specification,
however, this does not mesh well with the ALSA naming system. ALSA
generally expects enables rather than mutes and expects that mutes
and volumes have matching names.
Update the names and invert the mute controls to make them more
standard "FU XX Channel Switch", this does slightly deviate from
the SDCA specification but it makes the rest of the Linux ecosystem
a lot happier.

regulator_supply_alias_list was accessed without any locking in
regulator_supply_alias(), regulator_register_supply_alias(), and
regulator_unregister_supply_alias(). Concurrent registration,
unregistration and lookups can race, leading to:
1 use-after-free if an alias entry is removed while being read,
2 duplicate entries when two threads register the same alias,
3 inconsistent alias mappings observed by consumers.
Protect all traversals, insertions and deletions on
regulator_supply_alias_list with the existing regulator_list_mutex.

bits. See for instance ID_AA64SMFR0_EL1. The last user of this define,
ARM64_FEATURE_FIELD_BITS, is the set_id_regs selftest. Its logic assumes
the fields aren't a single bits; assert that's the case and stop using the

from the arm64 tools sysreg.h header. A separate commit removes this from

Merge series from Mikhail Kshevetskiy <mikhail.kshevetskiy@iopsys.eu>:
Airoha EN7523 snfi controller almost identical to AN7581 one, so the same
driver can be used. The only known difference appears in the very specific
boot conditions, when attached serial console force EN7523 SoC boots
in undocumented (reserved) mode. In this mode dma reading of the flash
works incorrectly.
This patch series:
* add support of EN7523 SoC
* add spinand node to en7523 dts (so spinand flash finally becomes usable)
* updates dt-bindings to mark driver as compatible with en7523
* disable dma usage to prevent possible data damage if booting in
reserved mode was detected.

min_t(int, a, b) casts an 'unsigned int' to 'int'. This might lead
to the cases when big number is wrongly chosen. On the other hand,
the SPI transfer length is unsigned and driver uses signed type for
an unknown reason. Change the type of the transfer length to be
unsigned and convert use min() instead of min_t().

Make sure to drop the reference taken when looking up the PMU device and
its regmap.
Note that holding a reference to a device does not prevent its regmap
from going away so there is no point in keeping the reference.

fill_pool_map is used to suppress nesting violations caused by acquiring
a spinlock_t (from within the memory allocator) while holding a
raw_spinlock_t. The used annotation is wrong.
LD_WAIT_SLEEP is for always sleeping lock types such as mutex_t.
LD_WAIT_CONFIG is for lock type which are sleeping while spinning on
PREEMPT_RT such as spinlock_t.
Use LD_WAIT_CONFIG as override.

The pool of free objects is refilled on several occasions such as object
initialisation. On PREEMPT_RT refilling is limited to preemptible
sections due to sleeping locks used by the memory allocator. The system
boots with disabled interrupts so the pool can not be refilled.
If too many objects are initialized and the pool gets empty then
debugobjects disables itself.
Refiling can also happen early in the boot with disabled interrupts as
long as the scheduler is not operational. If the scheduler can not
preempt a task then a sleeping lock can not be contended.
Allow to additionally refill the pool if the scheduler is not
operational.

The recent transition to use of_reserved_mem_region_to_resource()
changes the while loop to a for loop, but the increment of the "index"
variable was left behind at the end of the loop, as highlighted by the
following error/warning:
error: variable 'index' is incremented both in the loop header and in the loop body [-Werror,-Wfor-loop-analysis]
Drop the extra increment to avoid skipping over every other
memory-region in the loop.

suspend
Commit 8c3170628a9c ("wifi: brcmfmac: keep power during suspend if board
requires it") changed default behavior of the BRCMFMAC driver, which now
keeps SDIO card powered during system suspend to enable optional support
for WOWL. This feature is not supported by the legacy Exynos4 based
boards and leads to WLAN disfunction after system suspend/resume cycle.
Fix this by annotating SDIO host used by WLAN chip with
'cap-power-off-card' property, which should have been there from the
beginning.

Commit 78b72897a5c8 ("soc: samsung: exynos-pmu: Enable CPU Idle for
gs101") added system wide suspend/resume callbacks to Exynos PMU driver,
but some items used by these callbacks are initialized only on
GS101-compatible boards. Move that initialization to exynos_pmu_probe()
to avoid potential lockdep warnings like below observed during system
suspend/resume cycle:
INFO: trying to register non-static key.
The code is fine but needs lockdep annotation, or maybe
you didn't initialize this object before use?
turning off the locking correctness validator.

implied that all registered consoles have CON_ENABLED flag set, making
the check for the flag unnecessary. Call console_is_usable function to
