*	[SCSI] ufs: Separate PCI code into glue driver	Vinayak Holikatti	2013-02-25	5	-327/+440
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch separates PCI code from ufshcd.c and makes it as a core driver module and adds a new file ufshcd-pci.c as PCI glue driver.

*	[SCSI] ufs: Segregate PCI Specific Code	Vinayak Holikatti	2013-02-25	4	-219/+267
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch segregates the PCI specific code in ufshcd.c to make it ready for splitting into core ufs driver and PCI glue driver. Also copyright header modification to remove extra warranty disclaim.

*	Drivers: scsi: remove __dev* attributes.	Greg Kroah-Hartman	2013-01-04	1	-3/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

*	[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] 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>
