Pull ARM SoC platform updates from Olof Johansson:
"SoC changes, a substantial part of this is cleanup of some of the
older platforms that used to have a bunch of board files.
In particular:
- Remove non-DT i.MX platforms that haven't seen activity in years,
it's time to remove them.
- A bunch of cleanup and removal of platform data for TI/OMAP
platforms, moving over to genpd for power/reset control (yay!)
- Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them
closer to multiplatform support (not quite there yet, but getting
close).
There are a few other changes too, smaller fixlets, etc. For new
platform support, the primary ones are:
- New SoC: Hisilicon SD5203, ARM926EJ-S platform.
- Cpufreq support for i.MX7ULP"

This change fixes HS400 tuning for devices with invalid presets.
SDHCI presets are not currently used for eMMC HS/HS200/HS400, but are
used for DDR52. The HS400 retuning sequence is:
HS400->DDR52->HS->HS200->Perform Tuning->HS->HS400
This means that when HS400 tuning happens, we transition through DDR52
for a very brief period. This causes presets to be enabled
unintentionally and stay enabled when transitioning back to HS200 or
HS400. Some firmware has invalid presets, so we end up with driver
strengths that can cause I/O problems.

With the new SW tuning App note[1], a custom tuning algorithm is
required for eMMC HS200, HS400 and SD card UHS modes. The algorithm
involves running through the 32 possible input tap delay values and
sending the appropriate tuning command (CMD19/21) for each of them
to get a fail or pass result for each of the values. Typically, the
range will have a small contiguous failing window. Considering the
tuning range as a circular buffer, the algorithm then sets a final
tuned value directly opposite to the failing window.

DLL need only be enabled for speed modes and clock frequencies at or
above 50 MHz. For speed modes that don't enable the DLL, we need to
configure a static input delay value. This involves reading an optional
itap-del-sel-* value from the device tree and configuring it for the
appropriate speed mode.
With this addition, make sure that DLL is always switched off at the
beginning of the set_clock() call to simplify configuration. This also
removes the need for the dll_on member in struct sdhci_am654_data.

The MediaTek MMC driver uses pointer to get from private
msdc_host structure to the generic mmc_host structure.
However mmc_host always precedes msdc_host in memory so compute

Samsung S3C24xx and S3C64xx machine code cleanup for v5.10
Big cleanup for the Samsung S3C24xx and S3C64xx platforms, although it
also touches files shared with S5Pv210 and Exynos. This is mostly Arnd
Bergmann work which Krzysztof Kozlowski took over, rebased and polished.
The goal is to cleanup, merge and finally make the Samsung S3C24xx and
S3C64xx architectures multiplatform. The multiplatform did not happen
yet here - just cleaning up and merging into one arch/arm/mach-s3c
directory. However this is step forward for multiplatform or at least
to keep this code still maintainable.
This pulls also branch with changes for Samsung SoC sound drivers from
broonie/sound because the cleanups there were part of this series and
all further patches depend on them.

Some R-Car Gen3 SoCs need some manual correction of timing parameters
after the automatic tuning has finished but before next CMD13 is
completed. This patch implements that by this state machine:
- introducing a per-SoC correction table if needed
- iff such a table exists, the 'fixup_request' callback is populated
during probe
- iff such a table exists, a runtime flag ('needs_adjust_hs400')
is set when HS400 tuning was completed
- the callback will check the runtime flag and enable the corrected
manual mode if the flag is set and CMD13 is encountered
- at the end of the enablement the runtime flag is cleared
- iff the configuration flag is set, the manual mode will be disabled
when HS400 gets downgraded
There also some helper functions added to access the TMPPORT registers.
The actual correction table is SoC and instance(!) specific and is
added to the quirks struct.

Tuning procedure switches to lower frequencies but that will turn the
SCC off and accessing its register then will hang. So, check when we are
tuning and keep the current setup of the external clock if we are doing
so. Note that we still switch to the lower frequency because of the
internal divider. We just make sure to not modify the external clock.
This patch depends on a MMC core patch calling the downgrade function
earlier.

Turning on initcall debug on one system showed this:
initcall sdhci_msm_driver_init+0x0/0x28 returned 0 after 34782 usecs
The lion's share of this time (~33 ms) was in mmc_power_up(). This
shouldn't be terribly surprising since there are a few calls to delay
based on "power_delay_ms" and the default delay there is 10 ms.
Because we haven't specified that we'd prefer asynchronous probe for
this driver then we'll wait for this driver to finish before we start
probes for more drivers. While 33 ms doesn't sound like tons, every
little bit counts.
There should be little problem with turning on asynchronous probe for
this driver. It's already possible that previous drivers may have
turned on asynchronous probe so we might already have other things
(that probed before us) probing at the same time we are anyway. This
driver isn't really providing resources (clocks, regulators, etc) that
other drivers need to probe and even if it was they should be handling
-EPROBE_DEFER.
Let's turn this on and get a bit of boot speed back.

Since driver data is a pointer, direct casting to integer causes
warning when compile testing for 64-bit architecture:
drivers/mmc/host/s3cmci.c:1495:17: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
The actual driver data can be only 0 or 1, so cast it via long and do
not care about any loss of value.

Only -ENOENT from devm_clk_get() means that clock is not present in
device tree. Other errors have their own meaning and should not be
ignored.
Simplify getting the clock which is in fact optional and also use
dev_err_probe() for handling deferred.

dma_addr_t size varies between architectures so use dedicated printk
format to fix compile testing warning (e.g. on 32-bit MIPS):

Common pattern of handling deferred probe can be simplified with
dev_err_probe(). Less code, the error value gets printed and real error
from dw_mci_parse_dt() is passed further instead of fixed -EINVAL.
