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.

Similar to what has already been changed for eMMC and the MMC_SEND_OP_COND
(CMD1), let's convert the SD_APP_OP_COND (ACMD41) for SD cards to use the
common __mmc_poll_for_busy() too.
This change means the initial delay period, that starts as 10ms will now
increase for every loop when being busy. The total accepted timeout for
being busy is 1s, which is according to the SD spec.

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.

Some mmc host drivers may need to fixup a card-detection GPIO's config
to e.g. enable the GPIO controllers builtin pull-up resistor on devices
where the firmware description of the GPIO is broken (e.g. GpioInt with
PullNone instead of PullUp in ACPI DSDT).
Since this is the exception rather then the rule adding a config
parameter to mmc_gpiod_request_cd() seems undesirable, so instead
add a new mmc_gpiod_set_cd_config() function. This is simply a wrapper
to call gpiod_set_config() on the card-detect GPIO acquired through
mmc_gpiod_request_cd().

Modules registering driver with sdio_register_driver() might
forget to set .owner field. The field is used by some of other kernel
parts for reference counting (try_module_get()), so it is expected that
drivers will set it.
Solve the problem by moving this task away from the drivers to the core
code, just like we did for platform_driver in
commit 9447057eaf ("platform_device: use a macro instead of
platform_driver_register").
Since many drivers forget to set the .owner, this effectively will fix
them. Examples of fixed drivers are: ath6kl, b43, btsdio.c, ks7010,
libertas, MediaTek WiFi drivers, Realtek WiFi drivers, rsi, siano,
wilc1000, wl1251 and more.

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.
using sysfs or hotplug), the driver is just removed without the cleanup
being performed. This results in resource leaks. Fix it by compiling in the
remove callback unconditionally.

While STRB is currently used for DATA and CRC responses, the CMD
responses from the device to the host still require ITAPDLY for
HS400 timing.
Currently what is stored for HS400 is the ITAPDLY from High Speed
mode which is incorrect. The ITAPDLY for HS400 speed mode should
be the same as ITAPDLY as HS200 timing after tuning is executed.
Add the functionality to save ITAPDLY from HS200 tuning and save

Currently the sdhci_am654 driver only supports one tuning
algorithm which should be used only when DLL is enabled. The
ITAPDLY is selected from the largest passing window and the
buffer is viewed as a circular buffer.
The new algorithm should be used when the delay chain
is enabled. The ITAPDLY is selected from the largest passing
window and the buffer is not viewed as a circular buffer.
This implementation is based off of the following paper: [1].
Also add support for multiple failing windows.
