[PATCH 0/5] mmc: sdhci-msm: Corrections to implementation of power irq

[vviswana@codeaurora.org (Vijay Viswanath)]

Register writes which change voltage of IO lines or turn the IO bus on/off
require sdhc controller to be ready before progressing further. Once a
register write which affects IO lines is done, the driver should wait for
power irq from controller. Once the irq comes, the driver should acknowledge
the irq by writing to power control register. If the acknowledgement is not
given to controller, the controller may not complete the corresponding
register write action and this can mess up the controller if drivers proceeds
without power irq completing.
