mmc: Prevent 1.8V switch for SD hosts that don't support UHS modes.

2012-04-06T00:32:32+00:00

The driver should not try to switch to 1.8V when the SD 3.0 host
controller does not have any UHS capabilities bits set (SDR50, DDR50
or SDR104). See page 72 of "SD Specifications Part A2 SD Host
Controller Simplified Specification Version 3.00" under
"1.8V Signaling Enable". Instead of setting SDR12 and SDR25 in the host
capabilities data structure for all V3.0 host controllers, only set them
if SDR104, SDR50 or DDR50 is set in the host capabilities register. This
will prevent the switch to 1.8V later.

Revert "mmc: sdhci-pci: Add MSI support"

2012-04-06T00:32:32+00:00

This reverts commit e6039832bed9a9b967796d7021f17f25b625b616.
There are reports of MSI breaking SDHCI on multiple chipsets (JMicron
and O2Micro, at least), so this should be reverted until we come up
with a whitelist or something.

Revert "mmc: sdhci-pci: add quirks for broken MSI on O2Micro controllers"

2012-04-06T00:32:31+00:00

This reverts commit c16e981b2fd9455af670a69a84f4c8cf07e12658, because
it's no longer useful once MSI support is reverted.

mmc: omap_hsmmc: fix module re-insertion

2012-04-06T00:32:30+00:00

OMAP4 and OMAP3 HSMMC IP registers differ by 0x100 offset.
Adding the offset to platform_device resource structure
increments the start address for every insmod operation.
MMC command fails on re-insertion as module due to incorrect register
base.  Fix this by updating the ioremap base address only.

mmc: omap_hsmmc: convert to module_platform_driver

This will delete some boilerplate code, no functional changes.

mmc: omap_hsmmc: make it behave well as a module

2012-04-06T00:32:29+00:00

If we put probe() on __init section, that will never work for multiple
module insertions/removals.

In order to make it work properly, move probe to __devinit section and
use platform_driver_register() instead of platform_driver_probe().

mmc: omap_hsmmc: trivial cleanups

2012-04-06T00:32:28+00:00

A bunch of non-functional cleanups to the omap_hsmmc driver.

It basically decreases indentation level, drop unneded dereferences
and drop unneded accesses to the platform_device structure.

mmc: omap_hsmmc: context save after enabling runtime pm

2012-04-06T00:32:27+00:00

Call context save api after enabling runtime pm to make sure that
register access in context save api happens with clk enabled.

mmc: omap_hsmmc: use runtime put sync in probe error patch

2012-04-06T00:32:27+00:00

pm_runtime_put_sync instead of autosuspend pm runtime API
because iounmap(host->base) follows immediately.
