addc9ecb9d mmc: sdhci-of-ma35d1: Add Nuvoton MA35D1 SDHCI driver
Add the SDHCI driver for the MA35D1 platform. It is based upon the
SDHCI interface, but requires some extra initialization.

a1e627af32 mmc: mmc_test: Fix NULL dereference on allocation failure
If the "test->highmem = alloc_pages()" allocation fails then calling
__free_pages(test->highmem) will result in a NULL dereference.  Also
change the error code to -ENOMEM instead of returning success.

6275c7bc8d mmc: dw_mmc: allow biu and ciu clocks to defer
Fix a race condition if the clock provider comes up after mmc is probed,
this causes mmc to fail without retrying.
When given the DEFER error from the clk source, pass it on up the chain.

9374ae912d mmc: mtk-sd: receive cmd8 data when hs400 tuning fail
When we use cmd8 as the tuning command in hs400 mode, the command
response sent back by some eMMC devices cannot be correctly sampled
by MTK eMMC controller at some weak sample timing. In this case,
command timeout error may occur. So we must receive the following
data to make sure the next cmd8 send correctly.

c2a96b7f18 Driver core changes for 6.11-rc1
Here is the big set of driver core changes for 6.11-rc1.
 
 Lots of stuff in here, with not a huge diffstat, but apis are evolving
 which required lots of files to be touched.  Highlights of the changes
 in here are:
   - platform remove callback api final fixups (Uwe took many releases to
     get here, finally!)
   - Rust bindings for basic firmware apis and initial driver-core
     interactions.  It's not all that useful for a "write a whole driver
     in rust" type of thing, but the firmware bindings do help out the
     phy rust drivers, and the driver core bindings give a solid base on
     which others can start their work.  There is still a long way to go
     here before we have a multitude of rust drivers being added, but
     it's a great first step.
   - driver core const api changes.  This reached across all bus types,
     and there are some fix-ups for some not-common bus types that
     linux-next and 0-day testing shook out.  This work is being done to
     help make the rust bindings more safe, as well as the C code, moving
     toward the end-goal of allowing us to put driver structures into
     read-only memory.  We aren't there yet, but are getting closer.
   - minor devres cleanups and fixes found by code inspection
   - arch_topology minor changes
   - other minor driver core cleanups
 
 All of these have been in linux-next for a very long time with no
 reported problems.

63e555d9bf mmc: sdhci-esdhc-imx: obtain the 'per' clock rate after its enablement
The I.MX SDHCI driver assumes that the frequency of the 'per' clock
can be obtained even on disabled clocks, which is not always the case.

According to 'clk_get_rate' documentation, it is only valid
once the clock source has been enabled.

Some controllers may not be able to reach a bus clock as low as 400 KHz
due to a lack of sufficient divisors. In these cases, the SD card slot
becomes non-functional as Linux continuously attempts to set the bus
clock to 400 KHz. If the controller is incapable of getting that low,
set its minimum frequency instead. While this may eliminate some SD
cards, it allows those capable of operating at the controller's minimum
frequency to be used.

d69d804845 driver core: have match() callback in struct bus_type take a const *
In the match() callback, the struct device_driver * should not be
changed, so change the function callback to be a const *.  This is one
step of many towards making the driver core safe to have struct
device_driver in read-only memory.

Because the match() callback is in all busses, all busses are modified
to handle this properly.  This does entail switching some container_of()
calls to container_of_const() to properly handle the constant *.

For some busses, like PCI and USB and HV, the const * is cast away in
the match callback as those busses do want to modify those structures at
this point in time (they have a local lock in the driver structure.)
That will have to be changed in the future if they wish to have their
struct device * in read-only-memory.

ab069ce125 mmc: sdhci: Do not lock spinlock around mmc_gpio_get_ro()
sdhci_check_ro() can call mmc_gpio_get_ro() while holding the sdhci
host->lock spinlock. That would be a problem if the GPIO access done by
mmc_gpio_get_ro() needed to sleep.

However, host->lock is not needed anyway. The mmc core ensures that host
operations do not race with each other, and asynchronous callbacks like the
interrupt handler, software timeouts, completion work etc, cannot affect
sdhci_check_ro().

So remove the locking.

fbd64f902b mmc: sdhci: Do not invert write-protect twice
mmc_of_parse() reads device property "wp-inverted" and sets
MMC_CAP2_RO_ACTIVE_HIGH if it is true. MMC_CAP2_RO_ACTIVE_HIGH is used
to invert a write-protect (AKA read-only) GPIO value.

sdhci_get_property() also reads "wp-inverted" and sets
SDHCI_QUIRK_INVERTED_WRITE_PROTECT which is used to invert the
write-protect value as well but also acts upon a value read out from the
SDHCI_PRESENT_STATE register.

Many drivers call both mmc_of_parse() and sdhci_get_property(),
so that both MMC_CAP2_RO_ACTIVE_HIGH and
SDHCI_QUIRK_INVERTED_WRITE_PROTECT will be set if the controller has
device property "wp-inverted".

Amend the logic in sdhci_check_ro() to allow for that possibility,
so that the write-protect value is not inverted twice.

Also do not invert the value if it is a negative error value. Note that
callers treat an error the same as not-write-protected, so the result is
functionally the same in that case.

Also do not invert the value if sdhci host operation ->get_ro() is used.
None of the users of that callback set SDHCI_QUIRK_INVERTED_WRITE_PROTECT
directly or indirectly, but two do call mmc_gpio_get_ro(), so leave it to
them to deal with that if they ever set SDHCI_QUIRK_INVERTED_WRITE_PROTECT
in the future.

To fix the problem let's override the host_ops->card_busy() callback by
setting it to NULL, which forces the mmc core to poll with a CMD13 and
checking the R1_STATUS in the mmc_busy_cb() function.

a91bf3b3be mmc: sdhci-pci-o2micro: Convert PCIBIOS_* return codes to errnos
sdhci_pci_o2_probe() uses pci_read_config_{byte,dword}() that return
PCIBIOS_* codes. The return code is then returned as is but as
sdhci_pci_o2_probe() is probe function chain, it should return normal
errnos.

Convert PCIBIOS_* returns code using pcibios_err_to_errno() into normal
errno before returning them. Add a label for read failure so that the
conversion can be done in one place rather than on all of the return
statements.

The flag is now inherited by blk_stack_limits, which greatly simplifies

bd4a633b6f block: move the nonrot flag to queue_limits
Move the nonrot flag into the queue_limits feature field so that it can
be set atomically with the queue frozen.

Use the chance to switch to defaulting to non-rotational and require
the driver to opt into rotational, which matches the polarity of the
sysfs interface.

For the z2ram, ps3vram, 2x memstick, ubiblock and dcssblk the new
rotational flag is not set as they clearly are not rotational despite
this being a behavior change.  There are some other drivers that
unconditionally set the rotational flag to keep the existing behavior
as they arguably can be used on rotational devices even if that is
probably not their main use today (e.g. virtio_blk and drbd).

The flag is automatically inherited in blk_stack_limits matching the
existing behavior in dm and md.

1122c0c1cc block: move cache control settings out of queue->flags
Move the cache control settings into the queue_limits so that the flags
can be set atomically with the device queue frozen.

Add new features and flags field for the driver set flags, and internal
(usually sysfs-controlled) flags in the block layer.  Note that we'll
eventually remove enough field from queue_limits to bring it back to the
previous size.

The disable flag is inverted compared to the previous meaning, which
means it now survives a rescan, similar to the max_sectors and
max_discard_sectors user limits.

The FLUSH and FUA flags are now inherited by blk_stack_limits, which
simplified the code in dm a lot, but also causes a slight behavior
change in that dm-switch and dm-unstripe now advertise a write cache
despite setting num_flush_bios to 0.  The I/O path will handle this
gracefully, but as far as I can tell the lack of num_flush_bios
and thus flush support is a pre-existing data integrity bug in those
targets that really needs fixing, after which a non-zero num_flush_bios
should be required in dm for targets that map to underlying devices.

68dbe38ed7 mmc: renesas_sdhi: Set the SDBUF after reset
For development purpose, renesas_sdhi_probe() could be called w/
dma_ops = NULL to force the usage of PIO mode. In this case the
renesas_sdhi_enable_dma() will not be called before transferring data.

If renesas_sdhi_enable_dma() is not called, renesas_sdhi_clk_enable()
call from renesas_sdhi_probe() will configure SDBUF by calling the
renesas_sdhi_sdbuf_width() function, but then SDBUF will be reset in
tmio_mmc_host_probe() when calling tmio_mmc_reset() though host->reset().
If SDBUF is zero the data transfer will not work in PIO mode for RZ/G3S.

To fix this call again the renesas_sdhi_sdbuf_width(host, 16) in
renesas_sdhi_reset(). The call of renesas_sdhi_sdbuf_width() was not
removed from renesas_sdhi_clk_enable() as the host->reset() is optional.
