This accessor function does not help readability but makes it worse.
Because I soon need to read from the registers as well and don't want to
add another function like this, I chose to remove the existing one and
use the accessor directly. I also switch from writeq to writel because
no 64 bit register is actually involved.

1. The memory that allocated in mmc_alloc_host() is leaked.
2. In the remove() path, mmc_remove_host() will be called to
delete device, but it's not added yet, it will lead a kernel

This driver often takes on the order of 10ms to start, but in some cases
as much as 190ms. It shouldn't have many cross-device dependencies to
race with, nor racy access to shared state with other drivers, so this
should be a relatively low risk change. We've done similarly with a
variety of other MMC host drivers already.
This driver was pinpointed as part of a survey of top slowest initcalls
(i.e., are built in, and probing synchronously) on a lab of ChromeOS

For standard tuning method on usdhc, the previous tuning result can
impact current tuning result, let current tuning can't set the correct
delay cell. And from the logic, this is also reasonable for manual
tuning method. So reset the tuning logic before execute tuning.
To avoid compile issue, this patch also move the esdhc_reset_tuning()
upper.
Find this issue when support SDIO WiFi in band wakeup feature. After
system resume back, will do re-tuning, but then meet data CRC error.
Do not meet this issue on SD/eMMC, because we already call
esdhc_reset_tuning() when config the legency ios, and SD/eMMC need
to re-init when system resume back, but SDIO device don't do re-init
if it has MMC_PM_KEEP_POWER pm_flags.

kmap_local_page() is equivalent to kmap_atomic() except that it does not
disable page faults or preemption. Where possible kmap_local_page() is
preferred to kmap_atomic() - refer kernel highmem documentation.
In this case, there is no need to disable page faults or preemption, so
replace kmap_atomic() with kmap_local_page(), and, correspondingly,

Commit 20b92a30b5 ("mmc: sdhci: update signal voltage switch code")
removed voltage switch delays from sdhci because mmc core had been
enhanced to support them. However that assumed that sdhci_set_ios()
did a single clock change, which it did not, and so the delays in mmc
core, which should have come after the first clock change, were not
effective.
Fix by avoiding re-configuring UHS and preset settings when the clock
is turning on and the settings have not changed. That then also avoids
the associated clock changes, so that then sdhci_set_ios() does a single
clock change when voltage switching, and the mmc core delays become
effective.
To do that has meant keeping track of driver strength (host->drv_type),
and cases of reinitialization (host->reinit_uhs).
Note also, the 'turning_on_clk' restriction should not be necessary
but is done to minimize the impact of the change on stable kernels.

In mmc_select_voltage(), if there is no full power cycle, the voltage
range selected at the end of the function will be on a single range
(e.g. 3.3V/3.4V). To keep a range around the selected voltage (3.2V/3.4V),
the mask shift should be reduced by 1.
This issue was triggered by using a specific SD-card (Verbatim Premium
16GB UHS-1) on an STM32MP157C-DK2 board. This board cannot do UHS modes
and there is no power cycle. And the card was failing to switch to
high-speed mode. When adding the range 3.2V/3.3V for this card with the
proposed shift change, the card can switch to high-speed mode.

SDHCI_RESET_ALL resets will reset the hardware CQE state, but we aren't
tracking that properly in software. When out of sync, we may trigger
various timeouts.
It's not typical to perform resets while CQE is enabled, but one
particular case I hit commonly enough: mmc_suspend() -> mmc_power_off().
Typically we will eventually deactivate CQE (cqhci_suspend() ->
cqhci_deactivate()), but that's not guaranteed -- in particular, if
we perform a partial (e.g., interrupted) system suspend.
The same bug was already found and fixed for two other drivers, in v5.7
and v5.9:
5cf583f1fb ("mmc: sdhci-msm: Deactivate CQE during SDHC reset")
df57d73276 ("mmc: sdhci-pci: Fix SDHCI_RESET_ALL for CQHCI for Intel
GLK-based controllers")
The latter is especially prescient, saying "other drivers using CQHCI
might benefit from a similar change, if they also have CQHCI reset by
SDHCI_RESET_ALL."
So like these other patches, deactivate CQHCI when resetting the
controller. Do this via the new sdhci_and_cqhci_reset() helper.

Several SDHCI drivers need to deactivate command queueing in their reset
hook (see sdhci_cqhci_reset() / sdhci-pci-core.c, for example), and
several more are coming.
Those reset implementations have some small subtleties (e.g., ordering
of initialization of SDHCI vs. CQHCI might leave us resetting with a
NULL ->cqe_private), and are often identical across different host
drivers.
We also don't want to force a dependency between SDHCI and CQHCI, or
vice versa; non-SDHCI drivers use CQHCI, and SDHCI drivers might support
command queueing through some other means.
So, implement a small helper, to avoid repeating the same mistakes in
different drivers. Simply stick it in a header, because it's so small it
doesn't deserve its own module right now, and inlining to each driver is
pretty reasonable.
This is marked for -stable, as it is an important prerequisite patch for
several SDHCI controller bugfixes that follow.

was removed, so there is no reason to check. Furthermore ensure
part_curr is not falsely set to a valid value on reset or
partition switch error.
As part of this change the code paths of mmc_blk_reset calls were checked
to ensure no commands are issued after a failed mmc_blk_reset directly
without going through the block layer.

Pull more random number generator updates from Jason Donenfeld:
"This time with some large scale treewide cleanups.
The intent of this pull is to clean up the way callers fetch random
integers. The current rules for doing this right are:
- If you want a secure or an insecure random u64, use get_random_u64()
- If you want a secure or an insecure random u32, use get_random_u32()
The old function prandom_u32() has been deprecated for a while
now and is just a wrapper around get_random_u32(). Same for
get_random_int().
- If you want a secure or an insecure random u16, use get_random_u16()
- If you want a secure or an insecure random u8, use get_random_u8()
- If you want secure or insecure random bytes, use get_random_bytes().
The old function prandom_bytes() has been deprecated for a while
now and has long been a wrapper around get_random_bytes()
- If you want a non-uniform random u32, u16, or u8 bounded by a
certain open interval maximum, use prandom_u32_max()
I say "non-uniform", because it doesn't do any rejection sampling
or divisions. Hence, it stays within the prandom_*() namespace, not
the get_random_*() namespace.
I'm currently investigating a "uniform" function for 6.2. We'll see
what comes of that.
By applying these rules uniformly, we get several benefits:
- By using prandom_u32_max() with an upper-bound that the compiler
can prove at compile-time is ≤65536 or ≤256, internally
get_random_u16() or get_random_u8() is used, which wastes fewer
batched random bytes, and hence has higher throughput.
- By using prandom_u32_max() instead of %, when the upper-bound is
not a constant, division is still avoided, because
prandom_u32_max() uses a faster multiplication-based trick instead.
- By using get_random_u16() or get_random_u8() in cases where the
return value is intended to indeed be a u16 or a u8, we waste fewer
batched random bytes, and hence have higher throughput.
This series was originally done by hand while I was on an airplane
without Internet. Later, Kees and I worked on retroactively figuring
out what could be done with Coccinelle and what had to be done
manually, and then we split things up based on that.
So while this touches a lot of files, the actual amount of code that's
hand fiddled is comfortably small"

that the current value 400KHz is wrong.
Unfortunately this has also lead to fail to initialize some cards, which

Due to clk rounding errors on RZ/G2L platforms, it selects a clock source
with a lower clock rate compared to a higher one.
For eg: The rounding error (533333333 Hz / 4 * 4 = 533333332 Hz < 5333333
33 Hz) selects a clk source of 400 MHz instead of 533.333333 MHz.
This patch fixes this issue by adding a margin of (1/1024) higher to
the clock rate.

This loop intends to retry a max of 10 times, with some implicit
termination based on the SD_{R,}OCR_S18A bit. Unfortunately, the
termination condition depends on the value reported by the SD card
(*rocr), which may or may not correctly reflect what we asked it to do.
Needless to say, it's not wise to rely on the card doing what we expect;
we should at least terminate the loop regardless. So, check both the
input and output values, so we ensure we will terminate regardless of
the SD card behavior.
Note that SDIO learned a similar retry loop in commit 0797e5f145
("mmc: core: Fixup signal voltage switch"), but that used the 'ocr'
result, and so the current pre-terminating condition looks like:
rocr & ocr & R4_18V_PRESENT

bit 2 of the Bus Width Register. Thus the current bitmask is wrong: define
BUS_WIDTH_4 BIT(1)
BIT(1) does not work but BIT(2) works. This has been verified on real MOXA
hardware with FTSDC010 controller revision 1_6_0.
The corrected value of BUS_WIDTH_4 mask collides with: define BUS_WIDTH_8

module: kunit: Load .kunit_test_suites section when CONFIG_KUNIT=m
mmc: sdhci-of-aspeed: test: Fix dependencies when KUNIT=m
If re-initialization results is a different signal voltage, because the
voltage switch failed previously, but not this time (or vice versa), then
sd3_bus_mode will be inconsistent with the card because the SD_SWITCH
command is done only upon first initialization.
Fix by always reading SD_SWITCH information during re-initialization, which
also means it does not need to be re-read later for the 1.8V fixup
workaround.
Note, brief testing showed SD_SWITCH took about 1.8ms to 2ms which added
about 1% to 1.5% to the re-initialization time, so it's not particularly
significant.

When introduced, upon success, the 1.8V fixup workaround in
mmc_sd_init_card() would branch to practically the end of the function, to
a label named "done". Unfortunately, perhaps due to the label name, over
time new code has been added that really should have come after "done" not
before it. Let's fix the problem by moving the label to the correct place
and rename it "cont".

While the sdhci-of-aspeed KUnit tests do work when builtin, and do work
when KUnit itself is being built as a module, the two together break.
This is because the KUnit tests (understandably) depend on KUnit, so a
built-in test cannot build if KUnit is a module.
Fix this by adding a dependency on (MMC_SDHCI_OF_ASPEED=m || KUNIT=y),
which only excludes this one problematic configuration.
This was reported on a nasty openrisc-randconfig run by the kernel test
robot, though for some reason (compiler optimisations removing the test
code?) I wasn't able to reproduce it locally on x86:

The commit 08f3dff799 (mmc: sdhci-of-dwcmshc: add rockchip platform

chips. Unfortunately, it also breaks the BlueField-3 FW, which uses ACPI.
To fix the problem, let's add the ACPI match data and the corresponding
quirks to re-enable the support for the BlueField-3 SoC.

Currently we don't clear MSDC interrupts when cqe off/disable, which led
to the data complete interrupt will be reserved for the next command.
If the next command with data transfer after cqe off/disable, we process
the CMD ready interrupt and trigger DMA start for data, but the data
complete interrupt is already exists, then SW assume that the data transfer
is complete, SW will trigger DMA stop, but the data may not be transmitted
yet or is transmitting, so we may encounter the following error:

This KUnit update for Linux 5.20-rc1 consists of several fixes and an
important feature to discourage running KUnit tests on production
systems. Running tests on a production system could leave the system
in a bad state. This new feature adds:
- adds a new taint type, TAINT_TEST to signal that a test has been run.
This should discourage people from running these tests on production
systems, and to make it easier to tell if tests have been run
accidentally (by loading the wrong configuration, etc.)
- several documentation and tool enhancements and fixes.

Merge ACPI device object management changes for v5.20-rc1.
- Use the facilities provided by the driver core and some additional
helpers to handle the children of a given ACPI device object in
multiple places instead of using the children and node list heads in
struct acpi_device which is error prone (Rafael Wysocki).
- Fix ACPI-related device reference counting issue in the hisi_lpc bus
driver (Yang Yingliang).
- Drop the children and node list heads that are not needed any more
from struct acpi_device (Rafael Wysocki).
- Drop driver member from struct acpi_device (Uwe Kleine-König).
- Drop redundant check from acpi_device_remove() (Uwe Kleine-König).

Add support for eint IRQ when MSDC is used as an SDIO host. This
feature requires SDIO device support async IRQ function. With this
feature, SDIO host can be awakened by SDIO card in suspend state,
without additional pin.
MSDC driver will time-share the SDIO DAT1 pin. During suspend, MSDC
turn off clock and switch SDIO DAT1 pin to GPIO mode. And during
resume, switch GPIO function back to DAT1 mode then turn on clock.
Some device tree property should be added or modified in MSDC node
to support SDIO eint IRQ. Pinctrls "state_eint" is mandatory. Since
this feature depends on asynchronous interrupts, "wakeup-source",
"keep-power-in-suspend" and "cap-sdio-irq" flags are necessary, and
the interrupts list should be extended(the interrupt named with
sdio_wakeup):
&mmcX {
...
interrupt-names = "msdc", "sdio_wakeup";
interrupts-extended = <...>,
<&pio xxx IRQ_TYPE_LEVEL_LOW>;
...
pinctrl-names = "default", "state_uhs", "state_eint";
...
pinctrl-2 = <&mmc2_pins_eint>;
...
cap-sdio-irq;
keep-power-in-suspend;
wakeup-source;
...
};

3. Revert "mmc: sdhci-msm: Add SoC specific compatibles"
This reverts commit 466614a976.
The oldest commit 466614a976 ("mmc: sdhci-msm: Add SoC specific
compatibles") did not specify what benefits such multiple compatibles
bring, therefore assume there is none. On the other hand such approach
brings a lot of churn to driver maintenance by expecting commit for
every new compatible, even though it is already covered by the fallback.
There is really no sense in duplicating of_device_id for each
variant, which is already covered by generic compatible fallback
qcom,sdhci-msm-v4 or qcom,sdhci-msm-v5.

Due to flaws in hardware design, GL9763E takes long time to exit from L1
state. The I/O performance will suffer severe impact if it often enter and
exit L1 state during I/O requests.
To improve I/O read/write performance and take battery life into account,
let's turn on GL9763E L1 negotiation before entering runtime suspend and
turn off GL9763E L1 negotiation while executing runtime resume. That is to
say, GL9763E will not enter L1 state when executing I/O requests and enter
L1 state when PCIe bus idle.

The 72116B0 has improved SDIO controllers that allow the max clock
rate to be increased from a max of 100MHz to a max of 150MHz. The
driver will need to get the clock and increase it's default rate
and override the caps register, that still indicates a max of 100MHz.
The new clock will be named "sdio_freq" in the DT node's "clock-names"
list. The driver will use a DT property, "clock-frequency", to
enable this functionality and will get the actual rate in MHz
from the property to allow various speeds to be requested.

The kunit_test_suite() macro is no-longer incompatible with module_add,
so its use can be reinstated.
Since this fixes parsing with builtins and kunit_tool, also enable the
test by default when KUNIT_ALL_TESTS is enabled.
The test can now be run via kunit_tool with:
./tools/testing/kunit/kunit.py run --arch=x86_64 \
--kconfig_add CONFIG_OF=y --kconfig_add CONFIG_OF_ADDRESS=y \
--kconfig_add CONFIG_MMC=y --kconfig_add CONFIG_MMC_SDHCI=y \
--kconfig_add CONFIG_MMC_SDHCI_PLTFM=y \
--kconfig_add CONFIG_MMC_SDHCI_OF_ASPEED=y \
'sdhci-of-aspeed'
(It may be worth adding a .kunitconfig at some point, as there are
enough dependencies to make that command scarily long.)

With new API blk_mq_is_reserved_rq() we can tell if a request is from
the reserved pool, so stop passing 'reserved' arg. There is actually
only a single user of that arg for all the callback implementations, which
can use blk_mq_is_reserved_rq() instead.
This will also allow us to stop passing the same 'reserved' around the
blk-mq iter functions next.

Set the queue dying flag and call blk_mq_exit_queue from del_gendisk for
all disks that do not have separately allocated queues, and thus remove
the need to call blk_cleanup_queue for them.
Rename blk_cleanup_disk to blk_mq_destroy_queue to make it clear that
this function is intended only for separately allocated blk-mq queues.
This saves an extra queue freeze for devices without a separately
allocated queue.

Introduce acpi_device_fix_up_power_extended() for fixing up power of
a device having an ACPI companion in a manner that takes the device's
children into account and make the MMC code use it in two places
instead of walking the list of the device ACPI companion's children
directly.
This will help to eliminate the children list head from struct
acpi_device as it is redundant and it is used in questionable ways
in some places (in particular, locking is needed for walking the
list pointed to it safely, but it is often missing).

MediaTek IP requires that after dma stop, it need to wait this dma stop
bit auto-reset to 0. When bus is in high loading state, it will take a
while for the dma stop complete. If there is no waiting operation here,
when program runs to clear fifo and reset, bus will hang.
In addition, there should be no return in msdc_data_xfer_next() if
there is data need be transferred, because no matter what error occurs
here, it should continue to excute to the following mmc_request_done.
Otherwise the core layer may wait complete forever.

The second part of the multiplatform changes now converts the
Intel/Marvell PXA platform along with the rest. The patches went through
several rebases before the merge window as bugs were found, so they
remained separate.
This has to touch a lot of drivers, in particular the touchscreen,
pcmcia, sound and clk bits, to detach the driver files from the
platform and board specific header files.

The intention of the use of mmc_blk_reset_success() in
mmc_blk_cqe_recovery() was to prevent repeated resets when retrying and
getting the same error. However, that may not be the case - any amount
of time and I/O may pass before another recovery is needed, in which
case there would be no reason to deny it the opportunity to recover via
a reset if necessary. CQE recovery is expected seldom and failure to
recover (if the clear tasks command fails), even more seldom, so it is
better to allow the reset always, which can be done by calling
mmc_blk_reset_success() always.

It turned out that polling period for MMC_SEND_OP_COND, that currently is
set to 1ms, still isn't sufficient. In particular a Micron eMMC on a

Additional test, shows that extending the period to 4ms is working fine, so
let's make that change.

After a build regression report, I took a look at possible users of
CONFIG_ISA_DMA_API on m68k and found none, which Greg confirmed. The
CONFIG_GENERIC_ISA_DMA option in turn is only needed to implement
ISA_DMA_API, and is clearly not used on the platforms with ISA support.
The CONFIG_ISA support for AMIGA_PCMCIA is probably also unneeded,
but this is less clear. Unlike other PCMCIA implementations, this one
does not use the drivers/pcmcia subsystem at all and just supports
the "apne" network driver. When it was first added, one could use
ISA drivers on it as well, but this probably broke at some point.
With no reason to keep this, let's just drop the corresponding files
and prevent the remaining ISA drivers that use this from getting built.
The remaining definitions in asm/dma.h are used for PCI support.

Enabling this feature will allow the controller to stop the bus
clock when the bus is idle. The feature is not part of the standard
and is unique to newer Arasan cores and is enabled with a bit in a
vendor specific register. This feature will only be enabled for
non-removable devices because they don't switch the voltage and
clock gating breaks SD Card volatge switching.

Newer variants of the MMC controller support a 34-bit physical address
space by using word addresses instead of byte addresses. However, the
code truncates the DMA descriptor address to 32 bits before applying the
shift. This breaks DMA for descriptors allocated above the 32-bit limit.

To make the entropy pool a bit better we can toss in the

This does not count as improvement of the entropy but
in practice it makes it a bit more random to mix in these

Occasionally, user-land applications initiate longer timeout values for certain commands
through ioctl() system call. But so far we are still using a fixed timeout of 10 seconds
in mmc_poll_for_busy() on the ioctl() path, even if a custom timeout is specified in the
userspace application. This patch allows custom timeout values to override this default

In cases where this can't be connected, add a quirk to force the

Despite mmc_ioc_multi_cmd::num_of_cmds is a 64-bit field, its maximum
value is limited to MMC_IOC_MAX_CMDS (only 255); using a 64-bit local
variable to hold a copy of that field leads to gcc generating ineffective
loop code: despite the source code using an *int* variable for the loop
counters, the 32-bit object code uses 64-bit unsigned counters. Also,
gcc has to drop the most significant word of that 64-bit variable when
calling kcalloc() and assigning to mmc_queue_req::ioc_count anyway.
Using the *unsigned int* variable instead results in a better code.

we can convert now 'dmac_only_one_rx' from an ugly global flag to a
regular quirk. This makes quirk handling more consistent and easier to

Way back in commit 4f25580fb8 ("mmc: core: changes frequency to
hs_max_dtr when selecting hs400es"), Rockchip engineers noticed that
some eMMC don't respond to SEND_STATUS commands very reliably if they're
still running at a low initial frequency. As mentioned in that commit,
JESD84-B51 P49 suggests a sequence in which the host:
1. sets HS_TIMING
2. bumps the clock ("<= 52 MHz")
3. sends further commands
It doesn't exactly require that we don't use a lower-than-52MHz
frequency, but in practice, these eMMC don't like it.
The aforementioned commit tried to get that right for HS400ES, although
it's unclear whether this ever truly worked as committed into mainline,
as other changes/refactoring adjusted the sequence in conflicting ways:
08573eaf1a ("mmc: mmc: do not use CMD13 to get status after speed mode
switch")
53e60650f7 ("mmc: core: Allow CMD13 polling when switching to HS mode
for mmc")
In any case, today we do step 3 before step 2. Let's fix that, and also
apply the same logic to HS200/400, where this eMMC has problems too.
Resolves errors like this seen when booting some RK3399 Gru/Scarlet
systems:

[ 2.841751] mmc1: error -110 whilst initialising MMC card
Ealier versions of this patch bumped to 200MHz/HS200 speeds too early,
which caused issues on, e.g., qcom-msm8974-fairphone-fp2. (Thanks for
the report Luca!) After a second look, it appears that aligns with
JESD84 / page 45 / table 28, so we need to keep to lower (HS / 52 MHz)
rates first.

The mach/hardware.h is included in lots of places, and it provides
three different things on pxa:
- the cpu_is_pxa* macros
- an indirect inclusion of mach/addr-map.h
- the __REG() and io_pv2() helper macros
Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h
headers, then change all the files that use mach/hardware.h to
include the exact set of those three headers that they actually
need, allowing for further more targeted cleanup.
linux/soc/pxa/cpu.h can remain permanently exported and is now in
a global location along with similar headers. pxa-regs.h and
addr-map.h are only used in a very small number of drivers now
and can be moved to arch/arm/mach-pxa/ directly when those drivers
are to pass the necessary data as resources.

During the card initialization process, the mmc core checks whether the
eMMC/SD card supports an internal writeback-cache and then enables it
inside the card.
Unfortunately, this isn't according to what the mmc core reports to the
upper block layer. Instead, the writeback-cache support with REQ_FLUSH and
REQ_FUA, are being enabled depending on whether the host supports the CMD23
(MMC_CAP_CMD23) and whether an eMMC supports the reliable-write command.
This is wrong and it may also sound awkward. In fact, it's a remnant
from when both eMMC/SD cards didn't have dedicated commands/support to
control the internal writeback-cache. In other words, it was the best we
could do at that point in time.
To fix the problem, but also without breaking backwards compatibility,
let's align the REQ_FLUSH support with whether the writeback-cache became
successfully enabled - for both eMMC and SD cards.

Introduce a SEND_STATUS check for writes through SPI to not mark
an unsuccessful write as successful.
Since SPI SD/MMC does not have states, after a write, the card will
just hold the line LOW until it is ready again. The driver marks the
write therefore as completed as soon as it reads something other than
all zeroes.
The driver does not distinguish from a card no longer signalling busy
and it being disconnected (and the line being pulled-up by the host).
This lead to writes being marked as successful when disconnecting
a busy card.
Now the card is ensured to be still connected by an additional CMD13,
just like non-SPI is ensured to go back to TRAN state.
While at it and since we already poll for the post-write status anyway,
we might as well check for SPIs error bits (any of them).
The disconnecting card problem is reproducable for me after continuous
write activity and randomly disconnecting, around every 20-50 tries
on SPI DS for some card.

The overwhelming bulk of this pull request is a change from Uwe
Kleine-König which changes the return type of the remove() function to
void as part of some wider work he's doing to do this for all bus types,
causing updates to most SPI device drivers. The branch with that on has
been cross merged with a couple of other trees which added new SPI
drivers this cycle, I'm not expecting any build issues resulting from
the change.
Otherwise it's been a relatively quiet release with some new device
support, a few minor features and the welcome completion of the
conversion of the subsystem to use GPIO descriptors rather than numbers:
- Change return type of remove() to void.
- Completion of the conversion of SPI controller drivers to use GPIO
descriptors rather than numbers.
- Quite a few DT schema conversions.
- Support for multiple SPI devices on a bus in ACPI systems.
- Big overhaul of the PXA2xx SPI driver.
- Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and
Sunplus SP7021.

The driver prints the following log everytime data is written to RPMB:
mtk-msdc 11230000.mmc: phase: [map:ffffffff] [maxlen:32] [final:10]
dev_info is used to print that log but it seems that log is only
useful for debbuging. Use dev_dbg instead of dev_info.

Add runtime PM for GL9763E and disable PLL in runtime suspend. So power
gated of upstream port can be enabled. GL9763E has an auxiliary power
so it keep states in runtime suspend. In runtime resume, PLL is enabled
and waits for it to stabilize.

When mmc_select_hs400es() tries to switch to the HS400 ES mode, it may bail
out early if the host doesn't support an 8-bit buswidth, as it's required
for the HS400 mode.
To improve the situation, let's instead drop the HS400 bits from the
capability field if the 8-bit bus isn't supported. In this way, we allow
the mmc initialization to continue by trying a lower speed mode.
