Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.
No functional changes.

sdhci uses CONFIG_MMC_DEBUG for showing ADMA descriptor
when occurring ADMA error. And it's also used to dump the
registers whenever calling sdhci_add_host.
On one hand, I don't see any burden to always print the state
ADMA descriptor as it's rare and will help folks better understand
what was happening when seeing ADMA error.
On the other, folks may be interested in checking some registers
at probe time. So we remove the sdhci_dumpregs from __sdhci_add_host
and print some really useful registers in sdhci_setup_host.

The intention of this check was to prevent the conflict between

This adds deepest (Backup+Self-Refresh) PM support to the ATMEL SAMA5D2
SoC's SDHCI controller.
When resuming from deepest state, it is required to restore preset
registers as the registers are lost since VDD core has been shut down
when entering deepest state on the SAMA5D2. The clocks need to be
reconfigured as well.
The other registers and init process are taken care of by the SDHCI
core.

We got a warning:
drivers/mmc/host/atmel-mci.c:1086:15: warning: variable 'sg_len' set but
not used [-Wunused-but-set-variable]
Ideally we should check to see if sg_len is zero but looking
into the code closely, I didn't find any possible to do that as
atmci_start_request didn't even deploy any error handling for
its host->prepare_data hook. So even we return error value for iflags
like what other host drivers did, for instance, sdhci and dwmmc, it still
need some extra work to improve the code.
Just remove it to silent the warning, although it isn't perfect.

I always anticipated this code to be not correct, but now I had a test
case to prove it. According to all documentation I have, setting the
TMIO_STOP_STP bit ever only worked during block transfers. This bit is
like manually enforcing an autocmd12 during a so far seamless transfer.
It does NOT work when the block transfer had errors. It also does NOT
work with any other cmd except block commands. For all those, CMD12 has
to be treated like any other command. So, basically, we could use this
bit only for mrq->data->stop cmds. But for these, we happily use the
autocmd12 feature using the TMIO_STOP_SEC bit. As a result, the above
bit is not useful for us and we need to treat CMD12 as a regular cmd
always. Just remove the special handling code. Note that the BSP
recognized this issue as well yet had a more cautious solution to the
problem [1]. Which is understandable but makes CMD12 handling even more
complicated.
Checked with a Renesas Salvator-X/M3-W which needed to send CMD12 when
retuning one of my SD cards.

Reduce max_segs to 64, a value that allows allocation of an entire
EDMA descriptor list within a single page - EDMA descriptors
are 40 bytes and the header is much larger. This avoids doing a
higher order GFP_ATOMIC allocation in edma_prep_slave_sg
when setting up a transfer which can potentially fail due to
fragmentation under heavy I/O load.
The current value of 1024 is unusually high in comparison to
other mmc host drivers which mostly use values of between 1
and 256. The EDMA driver at present splits lists above 20
segments in any case so reducing the size of lists we pass to
it shouldn't add much overhead.

Freeing from the middle of allocated memory had all kinds of nasty
