-The Armada XP GPIO controller has two ways of notifying interrupts:
-using global interrupts or using per-CPU interrupts. In an attempt to
-use the best available features, the 'marvell,armadaxp-gpio'
-compatible string selects a variant of the gpio-mvebu driver that
-makes use of the per-CPU interrupts.
-
-Unfortunately, this doesn't work properly in a SMP context, because we
-fall into cases where the GPIO interrupt is enabled on CPU X at the
-GPIO controller level, but on CPU Y at the interrupt controller
-level. It is not yet clear how to fix that easily.
-
-So for 3.8, our approach is to switch to global interrupts for GPIOs,
-so that we do not fall into this per-CPU interrupts problem.
-
-This patch therefore fixes GPIO interrupts on Armada XP
-platforms. Without this patch, GPIO interrupts simply do not work
-reliably, because their proper operation depends on which CPU the code
-requesting the interrupt is running.

This patch adds a simple Device Tree binding for the mvsdio driver, as
well as the necessary documentation for it. Compatibility with non-DT
platforms is preserved, by keeping the platform_data based
the "clock" field of the mvsdio_platform_data structure.

On many Marvell SoCs, the pins used for the SDIO interface are part of
the MPP pins, that are muxable pins. In order to get the muxing of
those pins correct, this commit integrates the mvsdio driver with the
infrastructure.
