[SCSI] ufshcd: UFS Host controller driver 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> 2012-02-29 06:41:50 +00:00			`#`
