It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.

Currently .get_max_clock returns the current clock rate for cclk_emmc
on rk35xx, thus max clock gets set to whatever bootloader set it to.
In case of u-boot, it is intentionally reset to 50 MHz if it boots
from eMMC, see mmc_deinit() in u-boot sources. As a result, HS200 and
HS400 modes are never selected by Linux, because dwcmshc_rk35xx_postinit
clears appropriate caps if host->mmc->f_max is < 52MHz
cclk_emmc is not a fixed clock on rk35xx, so using
sdhci_pltfm_clk_get_max_clock is not appropriate here.
Implement rk35xx_get_max_clock that returns actual max clock for cclk_emmc.

R-Car H3 ES1.* was only available to an internal development group and
needed a lot of quirks and workarounds. These become a maintenance
burden now, so our development group decided to remove upstream support
and disable booting for this SoC. Public users only have ES2 onwards.

Add support to read the optional "gate" clock property and request the
clock which will be used to ungate the DLL clock.
For Xilinx platforms which has DLL module, dll clock must be
ungated/enabled when SD controller operates at higher frequencies like 50
MHz, 100 MHz and 200 MHz. This will be done by explicitly requesting gate
clock from the driver.

As usual, there are lots of minor driver changes across SoC platforms
from NXP, Amlogic, AMD Zynq, Mediatek, Qualcomm, Apple and Samsung.
These usually add support for additional chip variations in existing
drivers, but also add features or bugfixes.
The SCMI firmware subsystem gains a unified raw userspace interface
through debugfs, which can be used for validation purposes.
Newly added drivers include:
- New power management drivers for StarFive JH7110, Allwinner D1 and
Renesas RZ/V2M
- A driver for Qualcomm battery and power supply status
- A SoC device driver for identifying Nuvoton WPCM450 chips
- A regulator coupler driver for Mediatek MT81xxv

Here is the large set of driver core changes for 6.3-rc1.
There's a lot of changes this development cycle, most of the work falls
into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be moved
into read-only memory (i.e. const) The recent work with Rust has
pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only making
things safer overall. This is the contuation of that work (started
last release with kobject changes) in moving struct bus_type to be
constant. We didn't quite make it for this release, but the
remaining patches will be finished up for the release after this
one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems.

This is a follow-up to the deprecation of most of the old-style board
files that was merged in linux-6.0, removing them for good.
This branch is almost exclusively dead code removal based on those
annotations. Some device driver removals went through separate subsystem
trees, but the majority is in the same branch, in order to better handle
dependencies between the patches and avoid breaking bisection.
Unfortunately that leads to merge conflicts against other changes in the
subsystem trees, but they should all be trivial to resolve by removing
the files.
See commit 7d0d3fa733 ("Merge tag 'arm-boardfiles-6.0' of
git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc") for the
description of which machines were marked unused and are now removed. The
only removals that got postponed are Terastation WXL (mv78xx0) and
Jornada720 (StrongARM1100), which turned out to still have potential
users.

mmc_alloc_host() returns NULL pointer not PTR_ERR(), if it
fails, so replace the IS_ERR() check with NULL pointer check.
In commit 418f7c2de1 ("mmc: meson-gx: use devm_mmc_alloc_host"),
it checks NULL pointer not PTR_ERR, if devm_mmc_alloc_host() fails,
so make it to return NULL pointer to keep same with mmc_alloc_host(),
the drivers don't need to change the error handle when switch to
use devm_mmc_alloc_host().

Let's align to the common busy polling behaviour for mmc ioctls, by
updating the below two corresponding parts, that comes into play when using
an R1B response for a command.
*) A command with an R1B response should be prepared by calling
mmc_prepare_busy_cmd(), which make us respects the host's busy timeout
constraints.
**) When an R1B response is being used and the host also supports HW busy
detection, we should skip to poll for busy completion.

If sdio_add_func() or sdio_init_func() fails, sdio_remove_func() can
not release the resources, because the sdio function is not presented
in these two cases, it won't call of_node_put() or put_device().
To fix these leaks, make sdio_func_present() only control whether
device_del() needs to be called or not, then always call of_node_put()
and put_device().
In error case in sdio_init_func(), the reference of 'card->dev' is
not get, to avoid redundant put in sdio_free_func_cis(), move the
get_device() to sdio_alloc_func() and put_device() to sdio_release_func(),
it can keep the get/put function be balanced.
Without this patch, while doing fault inject test, it can get the
following leak reports, after this fix, the leak is gone.

This commit fixes a race between completion of stop command and start of a
new command.
Previously the command ready interrupt was enabled before stop command
was written to the command register. This caused the command ready
interrupt to fire immediately since the CMDRDY flag is asserted constantly
while there is no command in progress.
Consequently the command state machine will immediately advance to the
next state when the tasklet function is executed again, no matter
actual completion state of the stop command.
Thus a new command can then be dispatched immediately, interrupting and
corrupting the stop command on the CMD line.
Fix that by dropping the command ready interrupt enable before calling
atmci_send_stop_cmd. atmci_send_stop_cmd does already enable the
command ready interrupt, no further writes to ATMCI_IER are necessary.

SDHCI_QUIRK_MISSING_CAPS is not needed because sdhci_read_caps() can be
called instead.
In preparation to get rid of SDHCI_QUIRK_MISSING_CAPS, replace
SDHCI_QUIRK_MISSING_CAPS with sdhci_read_caps().
__sdhci_read_caps() is also called from sdhci_setup_host() via
sdhci_read_caps(), however only the first call to __sdhci_read_caps() does
anything because after that host->read_caps has been set to true.
Note, __sdhci_read_caps() does more than just set host->caps, such as do a
reset, so calling __sdhci_read_caps() earlier could have unforeseen
side-effects. However the code flow has been reviewed with that in mind.

USDHC IP has one limitation: the tuning circuit can't handle the async
sdio device interrupt correctly. When sdio device use 4 data lines,
async sdio interrupt will use the shared DAT[1], if enable auto tuning
circuit to check these 4 data lines, include the DAT[1], this circuit
will detect this interrupt, take this as data on DAT[1], and adjust the
delay cell wrongly, finally will cause the DATA/CMD CRC error.
So for SDIO device, only enable DAT[0] and CMD line for auto tuning.
To distinguish the card type during card init, involve init_card().

Pull random number generator updates from Jason Donenfeld:
- Replace prandom_u32_max() and various open-coded variants of it,
there is now a new family of functions that uses fast rejection
sampling to choose properly uniformly random numbers within an
interval:
get_random_u32_below(ceil) - [0, ceil)
get_random_u32_above(floor) - (floor, U32_MAX]
get_random_u32_inclusive(floor, ceil) - [floor, ceil]
Coccinelle was used to convert all current users of
prandom_u32_max(), as well as many open-coded patterns, resulting in
improvements throughout the tree.
I'll have a "late" 6.1-rc1 pull for you that removes the now unused
prandom_u32_max() function, just in case any other trees add a new
use case of it that needs to converted. According to linux-next,
there may be two trivial cases of prandom_u32_max() reintroductions
that are fixable with a 's/.../.../'. So I'll have for you a final
conversion patch doing that alongside the removal patch during the
second week.
This is a treewide change that touches many files throughout.
- More consistent use of get_random_canary().
- Updates to comments, documentation, tests, headers, and
simplification in configuration.
- The arch_get_random*_early() abstraction was only used by arm64 and
wasn't entirely useful, so this has been replaced by code that works
in all relevant contexts.
- The kernel will use and manage random seeds in non-volatile EFI
variables, refreshing a variable with a fresh seed when the RNG is
initialized. The RNG GUID namespace is then hidden from efivarfs to
prevent accidental leakage.
These changes are split into random.c infrastructure code used in the
EFI subsystem, in this pull request, and related support inside of
EFISTUB, in Ard's EFI tree. These are co-dependent for full
functionality, but the order of merging doesn't matter.
- Part of the infrastructure added for the EFI support is also used for
an improvement to the way vsprintf initializes its siphash key,
replacing an sleep loop wart.
- The hardware RNG framework now always calls its correct random.c
input function, add_hwgenerator_randomness(), rather than sometimes
going through helpers better suited for other cases.
- The add_latent_entropy() function has long been called from the fork
handler, but is a no-op when the latent entropy gcc plugin isn't
used, which is fine for the purposes of latent entropy.
But it was missing out on the cycle counter that was also being mixed
in beside the latent entropy variable. So now, if the latent entropy
gcc plugin isn't enabled, add_latent_entropy() will expand to a call
to add_device_randomness(NULL, 0), which adds a cycle counter,
without the absent latent entropy variable.
- The RNG is now reseeded from a delayed worker, rather than on demand
when used. Always running from a worker allows it to make use of the
CPU RNG on platforms like S390x, whose instructions are too slow to
do so from interrupts. It also has the effect of adding in new inputs
more frequently with more regularity, amounting to a long term
transcript of random values. Plus, it helps a bit with the upcoming
vDSO implementation (which isn't yet ready for 6.2).
- The jitter entropy algorithm now tries to execute on many different
CPUs, round-robining, in hopes of hitting even more memory latencies
and other unpredictable effects. It also will mix in a cycle counter
when the entropy timer fires, in addition to being mixed in from the
main loop, to account more explicitly for fluctuations in that timer
firing. And the state it touches is now kept within the same cache
line, so that it's assured that the different execution contexts will
cause latencies.

In case of error condition to avoid system crash Tegra SDMMC controller
requires CMD and DAT resets issued together. SDHCI controller FSM goes
into bad state due to rapid SD card hot-plug event. Issuing reset on the
CMD FSM before DATA FSM results in kernel panic, hence add support to
issue CMD and DAT resets together.
This is applicable to Tegra186 and later chips.

Let's use pr_err() to output the error messages and let's extend a comment
to clarify why returning 0 (success) in one case make sense.

To avoid glitches on the clock line, the card clock is disabled when making
timing changes. Do not do that separately for HISPD and UHS settings.

Current next_tag selection will cause a large delay in some requests and
destroy the scheduling results of the block scheduling layer. Because the
issued mrq tags cannot ensure that each time is sequential, especially when
the IO load is heavy. In the fio performance test, we found that 4k random
read data was sent to mmc_hsq to start calling request_atomic It takes
nearly 200ms to process the request, while mmc_hsq has processed thousands
of other requests. So we use fifo here to ensure the first in, first out
feature of the request and avoid adding additional delay to the request.

The workaround of pretending R1B non-data transfers are data transfers in
order for the busy timeout to be respected by the host controller driver is
removed. It wasn't useful in a long time.
Initially the workaround ensured that R1B commands did not time out by
setting the data timeout to be the command timeout in commit cb87ea28ed
("mmc: core: Add mmc CMD+ACMD passthrough ioctl"). This was moved inside an
if-clause with idata->buf_bytes being set in commit 4d6144de8b ("mmc:
core: check for zero length ioctl data"). Since the workaround is now
inside the idata->buf_bytes clause and intended to fix R1B non-data
transfers, that do not have buf_bytes set, we can remove the workaround
altogether. This was dead code, since data transfers doesn't use R1B
commands.

Add a macro to check for a quirk because it a) ensures that the check
for non-empty 'quirks' struct is not forgotten and b) is easier to read.
Convert existing quirk access as well.

Up to now, HS400 adjustment mode was only disabled on soft reset when a
calibration table was in use. It is safer, though, to disable it as soon
as the instance has an adjustment related quirk set, i.e. bad taps or a
calibration table.
