2016-09-30scsi: ufs: Kconfig fixJoao Pinto1-1/+1
Currently if we have PCI and UFSHCD configured in the kernel, both SCSI_UFS_DWC_TC_PCI and SCSI_UFSHCD_PCI show up, which is not correct. This patch changes the UFS Kconfig to assure hierarchy between the 2 options. Signed-off-by: Joao Pinto <jpinto@synopsys.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>

2016-03-18scsi: ufs: select CONFIG_NLSArnd Bergmann1-0/+1
A recent change to ufshcd introduced a call to utf16s_to_utf8s, a function that is provided by the NLS module, so we get a link error when that is not present: drivers/scsi/built-in.o: In function `ufshcd_read_string_desc': :(.text+0x124d0): undefined reference to `utf16s_to_utf8s' This adds a Kconfig 'select' statement to avoid the build error.

This change adds support for Qualcomm Technologies Inc platforms that use UFS driver. for example, it adds : - PM specific operations during hibern8, suspend, resume, clock setup - qcom-ufs generic phy driver initialization, calibration, power-on/off sequence, etc. - UFS Controller specific configuration - Rate, Gear, Mode negotiation between device and controller Signed-off-by: Yaniv Gardi <ygardi@codeaurora.org> Reviewed-by: Dov Levenglick <dovl@codeaurora.org> Signed-off-by: Christoph Hellwig <hch@lst.de>
2014-10-01ufs: Add support for clock scaling using devfreq frameworkSahitya Tummala1-0/+2
The clocks for UFS device will be managed by generic DVFS (Dynamic Voltage and Frequency Scaling) framework within kernel. This devfreq framework works with different governors to scale the clocks. By default, UFS devices uses simple_ondemand governor which scales the clocks up if the load is more than upthreshold and scales down if the load is less than downthreshold.

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>
