The RPi4 has an Arasan controller it carries over from the RPi3 and a newer
eMMC2 controller. Because of a couple of quirks, it seems wiser to bind
these controllers to the same driver that DT is using on this platform
rather than the generic sdhci_acpi driver with PNP0D40.
So, BCM2847 describes the older Arasan and BRCME88C describes the newer
eMMC2. The older Arasan is reusing an existing ACPI _HID used by other OSes
booting these tables on the RPi.
With this change, Linux is capable of utilizing the SD card slot, and the
Wi-Fi when booted with UEFI+ACPI on the RPi4.

The Aspeed SD/eMMC controllers expose configurable clock phase
correction by inserting delays of up to 15 logic elements in length into
the bus clock path. The hardware supports independent configuration for
both bus directions on a per-slot basis.
The timing delay per element encoded in the driver was experimentally
determined by scope measurements.
The phase controls for both slots are grouped together in a single
register of the global register block of the SD/MMC controller(s), which
drives the use of a locking scheme between the SDHCIs and the global
register set.

Drivers for MMC hosts that accept phase corrections can take advantage
of the helper by embedding an instance of struct mmc_clk_phase_map in

translate and apply the extracted values to hardware as required.

The MSM SDHCI driver always set the "actual_clock" field to 0. It had
a comment about it not being needed because we weren't using the
standard SDHCI divider mechanism and we'd just fallback to
"host->clock". However, it's still better to provide the actual
clock. Why?
1. It will make timeout calculations slightly better. On one system I
have, the eMMC requets 200 MHz (for HS400-ES) but actually gets 192
MHz. These are close, but why not get the more accurate one.
2. If things are seriously off in the clock driver and it's missing
rates or picking the wrong rate (maybe it's rounding up instead of
down), this will make it much more obvious what's going on.
NOTE: we have to be a little careful here because the "actual_clock"
field shouldn't include the multiplier that sdhci-msm needs
internally.

shutdown callback will be changed to calling sdhci-pltfm_suspend

RPMB write operation will return general fail.
However, no matter V4 is enabled or not, the dwcmshc's ARGUMENT2
register is 32-bit block count register which doesn't support stuff
bits of CMD23 argument. So let's handle this specific ACMD23 case.
From another side, this patch also prepare for future v4 enabling

redefined as 32bit block count which doesn't support stuff bits of
CMD23 argument.

Here is the big char/misc driver update for 5.11-rc1.
Continuing the tradition of previous -rc1 pulls, there seems to be more
and more tiny driver subsystems flowing through this tree.
Lots of different things, all of which have been in linux-next for a
while with no reported issues:
- extcon driver updates
- habannalab driver updates
- mei driver updates
- uio driver updates
- binder fixes and features added
- soundwire driver updates
- mhi bus driver updates
- phy driver updates
- coresight driver updates
- fpga driver updates
- speakup driver updates
- slimbus driver updates
- various small char and misc driver updates

Previous patches dropped the strict dependency on the OF_*
in the sdhci-xenon driver. As a result the ACPI support
can be introduced (except for the XENON_A3700 variant)
by adding the necessary ID's in the acpi_match_table.

As a preparation for supporting ACPI, modify the driver
to use the clk framework only when booting with DT -
otherwise rely on the configuration done by firmware.
For that purpose introduce also a custom SDHCI get_max_clock
callback.

In order to support both ACPI and DT, modify the driver
to use device_* routines for obtaining the properties
values.
