[ Upstream commit a0753ef66c ]
The commit 08f3dff799 (mmc: sdhci-of-dwcmshc: add rockchip platform
support") introduces the use of_device_get_match_data() to check for some
chips. Unfortunately, it also breaks the BlueField-3 FW, which uses ACPI.
To fix the problem, let's add the ACPI match data and the corresponding
quirks to re-enable the support for the BlueField-3 SoC.

Currently we don't clear MSDC interrupts when cqe off/disable, which led
to the data complete interrupt will be reserved for the next command.
If the next command with data transfer after cqe off/disable, we process
the CMD ready interrupt and trigger DMA start for data, but the data
complete interrupt is already exists, then SW assume that the data transfer
is complete, SW will trigger DMA stop, but the data may not be transmitted
yet or is transmitting, so we may encounter the following error:

If we reset because of an error, we need to preserve values for the

To achieve that, we introduce a 'preserve' parameter to the reset

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.

The second part of the multiplatform changes now converts the

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.

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.

It is pointless to loop through the function when status

To make it unambiguous that the hw_reset callback is for cards and not
for controllers, we add 'card' to the callback name and convert all
users in one go. We keep the argument as mmc_host, though, because the
callback is used very early when mmc_card is not yet populated.
