mmc_request_done() is sometimes called from interrupt or other atomic
context. Mostly all mmc_request_done() does is complete(), however it
contains code to retry on error, which uses ->request(). As the error
path is certainly not performance critical, this may be moved to the
waiting function mmc_wait_for_req_done().
This allows ->request() to use runtime PM get_sync() and guarantee it
is never in an atomic context.

Low voltage batteries have a wider voltage range with
lower operating voltages. Some consumers in the platform
may not work with the lower voltages and therefore need
an extra regulator to boost the voltage in this case.
This driver adds support for checking the consumers that
need higher voltage (Vaux1, 2 and 3 regulators, 3 V SIM)
and control the external buck/boost regulator
accordingly.
Note that to utilize the low voltage battery support,
the battery voltage thresholds must be changed. This
applies for the low battery voltage threshold of the
battery manager and the OTP setting for the AB8500
BattOk levels.

f39b2dd9d ("mmc: core: Bus width testing needs to handle suspend/resume")
added code to only compare read-only ext_csd fields in bus width testing
code, yet it's comparing some fields that are never set.
The affected fields are ext_csd.raw_erased_mem_count and
ext_csd.raw_partition_support.

For cards that support hardware reset (just eMMC), try a reset and
retry before returning an I/O error. However this is not done for
ECC errors and is never done twice for the same operation type
(READ, WRITE, DISCARD, SECURE DISCARD) until that type of operation
again succeeds.

eMMC's may have a hardware reset line. This patch provides a
host controller operation to implement hardware reset and
a function to reset and reinitialize the card. Also, for MMC,
the reset is always performed before initialization.
The host must set the new host capability MMC_CAP_HW_RESET
to enable hardware reset.

Put MMC to sleep if it supports SLEEP/AWAKE (CMD5) in the mmc suspend
so that Vcc (NAND core) can be cut to minimize power consumption.
eMMC put into SLEEP can respond to CMD0 or H/W reset or CMD5.
Current implemention on resume from suspend relies on CMD0 in
mmc_init_card to get out of SLEEP mode.

Stress-testing the runtime power management of libertas_sdio
through a rmmod/insmod loop revealed that it is quite easy to
cause an ETIMEDOUT failure in mmc_sdio_power_restore() leading to:
libertas_sdio: probe of mmc1:0001:1 failed with error -16
Experimentation shows that a very short delay (100us) is needed in
the power down path before the card can be successfully booted again.
We know that this setup is lacking poweroff clamps on the card's power
lines, but as only a short delay is needed, apply this unconditionally.
Also bump up to 1ms sleep for extra legroom.

This adds support to inject data errors after a completed host transfer.
The mmc core will return error even though the host transfer is successful.
This simple fault injection proved to be very useful to test the
non-blocking error handling in the mmc_blk_issue_rw_rq().
Random faults can also test how the host driver handles pre_req()
and post_req() in case of errors.

mmc_sd_init_uhs_card function sets the driver type, current limit
and bus speed mode on card as well as on host controller side.
Currently bus speed mode is set by sending CMD6 to card and
immediately setting the timing mode in host controller. But
then before initiating tuning sequence, it also tries to set
current limit by sending CMD6 to card which results in data
timeout errors in controller if bus speed mode is SDR50/SDR104 mode.
So basically bus speed mode should be set only after current limit
is set in the card and immediately after setting the bus speed mode,
tuning sequence should be initiated.

The default multithread workqueue can cause the same work to be executed
concurrently on a different CPUs. This isn't really suitable for clock
gating as it might already gated the clock and gating it twice results both
host->clk_old and host->ios.clock to be set to 0.
To prevent this from happening we use system_nrt_wq instead.
