In case of devm_reset_control_get_optional_exclusive() failure we returned
directly instead of jumping to the error path to roll back initialization.
This patch moves devm_reset_control_get_optional_exclusive() early in the
probe so that we have the reset handle prior to initialization of the
hardware.

Due to flaws in hardware design, GL9763E takes long time to exit from L1
state. The I/O performance will suffer severe impact if it often enter and
exit L1 state during I/O requests.
To improve I/O read/write performance and take battery life into account,
let's turn on GL9763E L1 negotiation before entering runtime suspend and
turn off GL9763E L1 negotiation while executing runtime resume. That is to
say, GL9763E will not enter L1 state when executing I/O requests and enter
L1 state when PCIe bus idle.

sdhci_pltfm_unregister() returns 0 unconditionally and returning an
error in a platform remove callback isn't very sensible. (The only
effect of the latter is that the device core emits a generic warning and
then removes the device anyhow.)
So return 0 unconditionally to make it obvious there is no error
forwarded to the upper layers.

if (res)
^~~

base_clk is used in the error path before it is initialized. Initialize
it to NULL, as clk_disable_unprepare() calls clk_disable() and
clk_unprepare(), which both handle NULL pointers gracefully.

The 72116B0 has improved SDIO controllers that allow the max clock
rate to be increased from a max of 100MHz to a max of 150MHz. The
driver will need to get the clock and increase it's default rate
and override the caps register, that still indicates a max of 100MHz.
The new clock will be named "sdio_freq" in the DT node's "clock-names"
list. The driver will use a DT property, "clock-frequency", to
enable this functionality and will get the actual rate in MHz
from the property to allow various speeds to be requested.

MediaTek IP requires that after dma stop, it need to wait this dma stop
bit auto-reset to 0. When bus is in high loading state, it will take a
while for the dma stop complete. If there is no waiting operation here,
when program runs to clear fifo and reset, bus will hang.
In addition, there should be no return in msdc_data_xfer_next() if
there is data need be transferred, because no matter what error occurs
here, it should continue to excute to the following mmc_request_done.
Otherwise the core layer may wait complete forever.

The second part of the multiplatform changes now converts the
Intel/Marvell PXA platform along with the rest. The patches went through
several rebases before the merge window as bugs were found, so they
remained separate.
This has to touch a lot of drivers, in particular the touchscreen,
pcmcia, sound and clk bits, to detach the driver files from the
platform and board specific header files.

This is quite a big update, partly due to the addition of some larger
drivers (more of which is to follow since at least the AVS driver is
still a work in progress) and partly due to Charles' work sorting out
our handling of endianness. As has been the case recently it's much
more about drivers than the core.
- Overhaul of endianness specification for data formats, avoiding
needless restrictions due to CODECs.
- Initial stages of Intel AVS driver merge.
- Introduction of v4 IPC mechanism for SOF.
- TDM mode support for AK4613.
- Support for Analog Devices ADAU1361, Cirrus Logic CS35L45, Maxim
MAX98396, MediaTek MT8186, NXP i.MX8 micfil and SAI interfaces,

After a build regression report, I took a look at possible users of
CONFIG_ISA_DMA_API on m68k and found none, which Greg confirmed. The
CONFIG_GENERIC_ISA_DMA option in turn is only needed to implement
ISA_DMA_API, and is clearly not used on the platforms with ISA support.
The CONFIG_ISA support for AMIGA_PCMCIA is probably also unneeded,
but this is less clear. Unlike other PCMCIA implementations, this one
does not use the drivers/pcmcia subsystem at all and just supports
the "apne" network driver. When it was first added, one could use
ISA drivers on it as well, but this probably broke at some point.
With no reason to keep this, let's just drop the corresponding files
and prevent the remaining ISA drivers that use this from getting built.
The remaining definitions in asm/dma.h are used for PCI support.

Since Qualcomm device-trees already use SoC specific compatibles for
describing the 'sdhci-msm' nodes, it makes sense to add the support for the
same in the driver as well.
Keep the old deprecated compatible strings still in the driver, to ensure
backward compatibility with older device-trees.

Enabling this feature will allow the controller to stop the bus
clock when the bus is idle. The feature is not part of the standard
and is unique to newer Arasan cores and is enabled with a bit in a
vendor specific register. This feature will only be enabled for
non-removable devices because they don't switch the voltage and
clock gating breaks SD Card volatge switching.

Newer variants of the MMC controller support a 34-bit physical address
space by using word addresses instead of byte addresses. However, the
code truncates the DMA descriptor address to 32 bits before applying the
shift. This breaks DMA for descriptors allocated above the 32-bit limit.

The ARASAN MMC controller on Keystone 3 class of devices need the SDCD
line to be connected for proper functioning. Similar to the issue pointed
out in sdhci-of-arasan.c driver, commit 3794c54264 ("mmc:
sdhci-of-arasan: Set controller to test mode when no CD bit").
In cases where this can't be connected, add a quirk to force the
controller into test mode and set the TESTCD bit. Use the flag
"ti,fails-without-test-cd", to implement this above quirk when required.

We iterate an extra time through the IRQ status handling
loop despite nothing had fired. Enabling the debug prints:

It is pointless to loop through the function when status
is zero. Just break the loop if the status is zero.
