2012-03-27[SCSI] ufshcd: UFS Host controller driverSantosh Yaraganavi
This patch adds support for Universal Flash Storage(UFS) host controllers. The UFS host controller driver includes host controller initialization method. The Initialization process involves following steps: - Initiate UFS Host Controller initialization process by writing to Host controller enable register - Configure UFS Host controller registers with host memory space datastructure offsets. - Unipro link startup procedure - Check for connected device - Configure UFS host controller to process requests - Enable required interrupts - Configure interrupt aggregation [jejb: fix warnings in 32 bit compile] Signed-off-by: Santosh Yaraganavi <santoshsy@gmail.com> Signed-off-by: Vinayak Holikatti <vinholikatti@gmail.com> Reviewed-by: Arnd Bergmann <arnd@linaro.org> Reviewed-by: Vishak G <vishak.g@samsung.com> Reviewed-by: Girish K S <girish.shivananjappa@linaro.org> Reviewed-by: Namjae Jeon <linkinjeon@gmail.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
