The Raspberry Pi devices have to date all used ARCH_BCM2835
as their SoC arch dependency so configurations that use this
and not BRCMSTB won't end up with this module in their config.

SDHCI_QUIRK_UNSTABLE_RO_DETECT is used by only one driver variant.
It was added in 2011 by commit 82b0e23a29 ("mmc: sdhci: Fix read-only
detection with JMicron 388 chip").
Simplify sdhci by moving the logic to the only place it is used.

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.

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.

When erase/trim/discard completion was converted to mmc_poll_for_busy(),
optional support to poll with the host_ops->card_busy() callback was also
added.
The common sdhci's ->card_busy() turns out not to be working as expected
for the sdhci-brcmstb variant, as it keeps returning busy beyond the card's
busy period. In particular, this leads to the below splat for
mmc_do_erase() when running a discard (BLKSECDISCARD) operation during

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.

The difference between old S3C64xx and newer Exynos4 SDHCI controller
variants is in clock handling (the "no_divider" field in drvdata).
Choose the proper sdhci_ops based on the variant instead of patching
ops in probe, if Exynos4 is used.
This allows making struct sdhci_ops const for code safety and probably
opens further options in the future, as the dynamic pointer ops table is
not anymore that dynamic.

The card-detect GPIO for the microSD slot on Asus T100TA / T100TAM models
stopped working under Linux after commit 6fd03f0248 ("gpiolib: acpi:
support bias pull disable").
The GPIO in question is connected to a mechanical switch in the slot
which shorts the pin to GND when a card is inserted.
The GPIO pin correctly gets configured with a 20K pull-up by the BIOS,
but there is a bug in the DSDT where the GpioInt for the card-detect is
configured with a PullNone setting:
GpioInt (Edge, ActiveBoth, SharedAndWake, PullNone, 0x2710,
"\\_SB.GPO0", 0x00, ResourceConsumer, ,
)
{ // Pin list
0x0026
}
Linux now actually honors the PullNone setting and disables the 20K pull-up
configured by the BIOS.
Add a new DMI_QUIRK_SD_CD_ENABLE_PULL_UP quirk which when set calls
mmc_gpiod_set_cd_config() to re-enable the pull-up and set this for
the Asus T100TA models to fix this.

Use the pci_set_power_state() interface instead because these are generic

requires some delays after these power transitions, and
pci_set_power_state() takes care of those, while d7133797e9 and

Using __exit for the remove function results in the remove callback being
discarded with CONFIG_MMC_DAVINCI=y. When such a device gets unbound (e.g.

Currently the sdhci_am654 driver only supports one tuning
algorithm which should be used only when DLL is enabled. The

buffer is viewed as a circular buffer.
The new algorithm should be used when the delay chain

window and the buffer is not viewed as a circular buffer.
This implementation is based off of the following paper: [1].

It seems the of_get_named_gpio() is solely used to check
if the GPIO is present in DT as the function can return 0
if and only if it's present and it becomes in the global
number space 0. But this quite likely shows that the code
wasn't ever been tested on the systems when no GPIO is provided.
In any case, the proper test is just to call of_property_present()
without any attempts in requesting GPIO (as we haven't saved the
number or descriptor anywhere in the code).

"PM runtime functions" was been added in sdhci-omap driver in commit
f433e8aac6 ("mmc: sdhci-omap: Implement PM runtime functions") along
with "card power off and enable aggressive PM" in commit 3edf588e7f
("mmc: sdhci-omap: Allow SDIO card power off and enable aggressive PM").
Since then, the sdhci-omap driver doesn't work using mmc-hs200 mode
due to the tuning values being lost during a pm transition.
As for the sdhci_am654 driver, request a new tuning sequence before
suspend (sdhci_omap_runtime_suspend()), otherwise the device will
trigger cache flush error:

This release sees some exciting changes from David Lechner which
implements some optimisations that have been talked about for a long
time which allows client drivers to pre-prepare SPI messages for
repeated or low latency use. This lets us move work out of latency
sensitive paths and avoid repeating work for frequently performed
operations. As well as being useful in itself this will also be used in
future to allow controllers to directly trigger SPI operations (eg, from
interrupts).
Otherwise this release has mostly been focused on cleanups, plus a
couple of new devices:
- Support for pre-optimising messages.
- A big set of updates from Uwe Kleine-König moving drivers to use APIs
with more modern terminology for controllers.
- Major overhaul of the s3c64xx driver.
- Support for Google GS101 and Samsung Exynos850.

Commit e519f0bb64 ("ARM/mmc: Convert old mmci-omap to GPIO descriptors")
moved Nokia N810 MMC power up/down from the board file into the MMC driver.
The change removed some delays, and ordering without a valid reason.
Restore power up/down to match the original code. This matters only on N810
where the 2nd GPIO is in use. Other boards will see an additional delay but
that should be a lesser concern than omitting delays altogether.

With the to-be-fixed commit, the reset_work handler cleared 'host->mrq'
outside of the spinlock protected critical section. That leaves a small
race window during execution of 'tmio_mmc_reset()' where the done_work
handler could grab a pointer to the now invalid 'host->mrq'. Both would
use it to call mmc_request_done() causing problems (see link below).
However, 'host->mrq' cannot simply be cleared earlier inside the
critical section. That would allow new mrqs to come in asynchronously
while the actual reset of the controller still needs to be done. So,
like 'tmio_mmc_set_ios()', an ERR_PTR is used to prevent new mrqs from
coming in but still avoiding concurrency between work handlers.

The introduction of sg_miter was a bit sloppy as it didn't
exactly mimic the semantics of the old code on multiblock reads
and writes: these like you to:
- Advance to the first sglist entry *before* starting to read
any blocks from the card.
- Advance and check availability of the next entry *right after*
processing one block.
Not checking if we have more sglist entries right after
reading a block will lead to this not being checked until we
return to the callback to read out more blocks, i.e. until the
next interrupt arrives. Since the last block is the last one
(no more data will arrive) there will not be a next interrupt,
and we will be waiting forever resulting in a timeout for
command 18 when reading multiple blocks.
The same bug was fixed also in the writing of multiple blocks.

The sg_miter used to loop over the returned sglist from a
transfer in the esdhc subdriver for SDHCI can be called
from atomic context so the miter needs to be atomic.
sdhci_request_done() is always called from process context,
either as a work or as part of the threaded interrupt handler,
but the one case when we are actually calling .request_done()
from an atomic context is in sdhci_irq().
Fix this by flagging the miter atomic so we always use
kmap_atomic().

Use the scatterlist memory iterator instead of just
dereferencing virtual memory using sg_virt().
This make highmem references work properly.
This driver also has a bug in the PIO sglist handling that
is fixed as part of the patch: it does not travers the
list of scatterbuffers: it will just process the first
item in the list. This is fixed by augmenting the logic
such that we do not process more than one sgitem
per IRQ instead of counting down potentially the whole
length of the request.
We can suspect that the PIO path is quite untested.

The whole scatterlist chain is submitted to the DMA engine,
but the code is written to just account for the length of
the first sg entry.
When the DMA transfer is finished, all the data in the
request has been transferred, account for this instead.
This only works because the moxart_request() function isn't
checking that all data was transferred and will
unconditionally issue mmc_request_done() after returning
successfully from moxart_transfer_dma().
Keep the assignment of accounted bytes in .bytes_xfered
but move it after the completion where we know it has
actually happened.
