mmc: core: Remove non-data R1B ioctl workaround
The workaround of pretending R1B non-data transfers are data transfers in
order for the busy timeout to be respected by the host controller driver is
removed. It wasn't useful in a long time.
Initially the workaround ensured that R1B commands did not time out by
setting the data timeout to be the command timeout in commit
cb87ea28ed9e
("mmc: core: Add mmc CMD+ACMD passthrough ioctl"). This was moved inside an
if-clause with idata->buf_bytes being set in commit
4d6144de8ba2 ("mmc:
core: check for zero length ioctl data"). Since the workaround is now
inside the idata->buf_bytes clause and intended to fix R1B non-data

altogether. This was dead code, since data transfers doesn't use R1B
commands.

For standard tuning method on usdhc, the previous tuning result can

tuning method. So reset the tuning logic before execute tuning.
To avoid compile issue, this patch also move the esdhc_reset_tuning()

Find this issue when support SDIO WiFi in band wakeup feature. After
system resume back, will do re-tuning, but then meet data CRC error.
Do not meet this issue on SD/eMMC, because we already call

Add dynamic configuration support for Xilinx ZynqMP which takes care of
configuring the SD secure space configuration registers using EEMI APIs,
performing SD reset assert and deassert.

- Check for the PM dynamic configuration support, if no error proceed with
SD dynamic configurations(next steps) otherwise skip the dynamic
configuration.
- Put the SD Controller in reset.
- Configure SD Fixed configurations.
- Configure the SD Slot Type.

Pull timer fix from Borislav Petkov:
- Revert a fix to RISC-V timers supposed to address an uncertainty
whether clock events are received during S3 or not which locks up
other RISC-V platforms. The issue will be fixed differently later.

"A few bug fixes around the handling of "Soft Reserved" memory and
memory tiering information.
Linux is starting to enounter more real world systems that deploy an
ACPI HMAT to describe different performance classes of memory, as well
the "special purpose" (Linux "Soft Reserved") designation from EFI.
These fixes result from that testing.
It has all appeared in -next for a while with no known issues.
- Fix duplicate overlapping device-dax instances for HMAT described
"Soft Reserved" Memory
- Fix missing node targets in the sysfs representation of memory
tiers
- Remove a confusing variable initialization"
