*	[SCSI] ufs: fix incorrect return value about SUCCESS and FAILED	Namjae Jeon	2012-07-20	1	-4/+6
\| \| \| \| \| \| \| \| \| \|	Currently the UFS host driver has returned incorrect values for SUCCESS and FAILED. Fix it to return the correct value to the upper layer.

*	[SCSI] ufs: reverse the ufshcd_is_device_present logic	Venkatraman S	2012-07-20	1	-3/+3

*	[SCSI] ufs: fix potential NULL pointer dereferencing error in ufshcd_prove.	Namjae Jeon	2012-05-23	1	-2/+3

*	[SCSI] ufs: Assign UTRLBAU = upper_32_ bits(UTRLD base address)	Santosh Yaraganavi	2012-05-10	1	-3/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	UTP Transfer request list base registers UTRLBA and UTRLBAU must be assigned, lower-32 and upper-32 bits of UTRLD list physical base addresses respectively. Currently UTRLBAU is being assigned lower-32 bits of UTRLD physical base address. This will cause an issue with controllers that can support 64-bit addressing. This patch correctly assigns upper-32 bits of UTRLD physical base address to UTRLBAU.

*	[SCSI] ufs: Fix evaluation of UTP task completion code	Venkatraman S	2012-05-10	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	While interpreting the result of UTP task completion status, by using boolean &&, the evaluation would fail when the UPIU_TASK_MANAGEMENT_FUNC_SUCCEEDED was received. Either UPIU_TASK_MANAGEMENT_FUNC_COMPL or UPIU_TASK_MANAGEMENT_FUNC_SUCCEEDED should be considered as a success result.

*	[SCSI] ufshcd: UFS Host controller driver	Santosh Yaraganavi	2012-03-27	5	-0/+2612
	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>
