6ba736a10e sdhci: handle dma boundary interrupts
When the device hits certain memory boundaries, it signals an
interrupt and expects to be serviced. We don't need the feature
but we need to make sure the device doesn't stall.

c0f3b6c777 mmc: au1xmmc command types check from data flags
This patch has changed command types check from data flags.

MMC_STOP_TRANSMISSION is never passed to au1xmmc_send_command().
SEND_STOP() is used for MMC_STOP_TRANSMISSION.

055b822414 disable socket power in adapter driver instead of media one
Socket power must be fully controlled by adapter driver. This also prevents
unnecessary power-off of the socket when media driver is unloaded, yet
media remains in the socket.

55556da012 MMC: Fix handling of low-voltage cards
Fix handling of low voltage MMC cards.

The latest MMC and SD specs both agree that support for
low-voltage operations is indicated by bit 7 in the OCR.
The MMC spec states that the low voltage range is
1.65-1.95V while the SD spec leaves the actual voltage
range undefined - meaning that there is still no such
thing as a low voltage SD card.

However, an old Sandisk spec implied that bits 7.0
represented voltages below 2.0V in 1V or 0.5V increments,
and the code was accordingly written with that expectation.

This confusion meant that host drivers attempting to support
the typical low voltage (1.8V) would set the wrong bits in
the host OCR mask (usually bits 5 and/or 6) resulting in the
the low voltage mode never being used.

This change corrects the low voltage range and adds sanity
checks on the reserved bits (0-6) and for SD cards that
claim to support low-voltage operations.

4be34c99a2 MMC: Consolidate voltage definitions
Consolidate the list of available voltages.

Up until now, a separate set of defines has been
used for host->vdd than that used for the OCR
voltage mask values. Having two sets of defines
allows them to get out of sync and the current
sets are already inconsistent with one claiming
to describe ranges and the other specific voltages.

Only the SDHCI driver uses the host->vdd defines and
it is easily fixed to use the OCR defines.
