Douglas Anderson 7320915c88 mmc: Set PROBE_PREFER_ASYNCHRONOUS for drivers that existed in v4.14
This is like commit 3d3451124f3d ("mmc: sdhci-msm: Prefer asynchronous
probe") but applied to a whole pile of drivers.  This batch converts
the drivers that appeared to be around in the v4.14 timeframe.

Tang Bin 92075d98ab mmc: cavium-octeon: remove nonsense variable coercion
In this function, the variable 'base' is already 'void __iomem *base',
and the return function 'devm_platform_ioremap_resource()' also returns
this type, so the mandatory definition here is redundant.

Markus Elfring 824b90bbaf mmc: cavium-octeon: Use devm_platform_ioremap_resource()
Simplify this function implementation by using a known wrapper function.

This issue was detected by using the Coccinelle software.

Jan Glauber 8fb83b1428 mmc: cavium: Fix probing race with regulator
If the regulator probing is not yet finished this driver
might catch a -EPROBE_DEFER. Returning after this condition
did not remove the created platform device. On a repeated
call to the probe function the of_platform_device_create
fails.

Calling of_platform_device_destroy after EPROBE_DEFER resolves
this bug.

David Daney 899e4aad15 mmc: cavium-octeon: Use proper GPIO name for power control
The devm_gpiod_get_optional() function appends a "-gpios" to the
string passed to it, so if we want to find the "power-gpios" signal,
we must pass "power" to this function.

David Daney aca69344c8 mmc: cavium-octeon: Fix interrupt enable code
OCTEON SoCs with CIU3 do not have interrupt masking local to the MMC
bus interface.  Unfortunately, some even have a diagnostic register at
the same address of the enable register, which causes the interrupts
to fire immediately if stored to, thus breaking the driver.  The proper
action on these SoCs is not to touch this register.
