MMC: S3C24XX: Add platform data for MMC/SD driver This patch adds platform data support to the s3mci driver. This allows flexible board-specific configuration of set_power, card detect and read only pins. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

s3cmci: add better support for no card detect or write protect available Add better support for omitting either the card detect or the write protect GPIOs if the board does not support it. Add the fields no_wprotect and no_detect to the platform data which when set indicate the absence of the respective GPIOs. Note, this also fixes a minor bug where it tries to free IRQ0 if there is no detect gpio available.

MMC: S3C24XX: Add media presence test to request handling. Ensure that we have physical media present before attempting to send a request to a card. This ensures that we do not get flooded by errors from commands that can never be completed timing out. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

s3cmci: Kconfig selection for PIO/DMA/Both Add a selection for the data transfer mode of the s3cmci driver, allowing for either a configuration or rumtime selection of the use of the DMA or PIO transfer code. The PIO only mode is 476 bytes smaller than the driver with both methods compiled in.
