The comment in mmc_sdio_power_restore() belongs in mmc_sdio_reinit_card(),

this by moving the comment into mmc_sdio_reinit_card().

The function mmc_sdio_power_restore() is called either from
mmc_sdio_runtime_resume() or from mmc_sdio_hw_reset(). Both callers either
claims/releases the host or require its callers to do so. Therefore let's
drop the redundant calls to mmc_claim|release_host() in
mmc_sdio_power_restore().

Processing of SDIO IRQs must obviously be prevented while the card is
system suspended, otherwise we may end up trying to communicate with an
uninitialized SDIO card.
Reports throughout the years shows that this is not only a theoretical
problem, but a real issue. So, let's finally fix this problem, by keeping
track of the state for the card and bail out before processing the SDIO
IRQ, in case the card is suspended.

We want SDIO drivers to be able to temporarily stop retuning when the
driver knows that the SDIO card is not in a state where retuning will
work (maybe because the card is asleep). We'll move the relevant
functions to a place where drivers can call them.

Normally when the MMC core sees an "-EILSEQ" error returned by a host
controller then it will trigger a retuning of the card. This is
generally a good idea.
However, if a command is expected to sometimes cause transfer errors
then these transfer errors shouldn't cause a re-tuning. This
re-tuning will be a needless waste of time. One example case where a
transfer is expected to cause errors is when transitioning between
idle (sometimes referred to as "sleep" in Broadcom code) and active
state on certain Broadcom WiFi SDIO cards. Specifically if the card
was already transitioning between states when the command was sent it
could cause an error on the SDIO bus.
Let's add an API that the SDIO function drivers can call that will
temporarily disable the auto-tuning functionality. Then we can add a
call to this in the Broadcom WiFi driver and any other driver that
might have similar needs.
NOTE: this makes the assumption that the card is already tuned well
enough that it's OK to disable the auto-retuning during one of these
error-prone situations. Presumably the driver code performing the
error-prone transfer knows how to recover / retry from errors. ...and
after we can get back to a state where transfers are no longer
error-prone then we can enable the auto-retuning again. If we truly
find ourselves in a case where the card needs to be retuned sometimes
to handle one of these error-prone transfers then we can always try a
few transfers first without auto-retuning and then re-try with
auto-retuning if the first few fail.
Without this change on rk3288-veyron-minnie I periodically see this in
the logs of a machine just sitting there idle:

2. The register field used to select DLL frequency is 3 bit wide as

On the Amlogic G12A SoC family, (only) the SDIO controller fails to access
the data from DRAM, leading to a broken controller.
But each MMC controller has 1,5KiB of SRAM after the registers, that can
be used as bounce buffer to avoid direct DRAM access from the integrated
DMAs (this SRAM may be used by the boot ROM when DRAM is not yet initialized).
The quirk is to disable the chained descriptor for this controller, and
use this SRAM memory zone as buffer for the bounce buffer fallback mode.
The performance hit hasn't been evaluated, but the fix has been tested
using a WiFi AP6398S SDIO module, and the iperf3 Bandwidth measurement gave
55.2 Mbits/sec over a 63 Hours long test, with the SDIO ios set as High-Speed
at 50MHz clock. It gave 170 Mbits/sec as SDR104 and 200MHz clock.
