This patch series adds programming support for Qualcomm UFS V4 and above to align avoid with Hardware Specification. This patch series will address stability and performance issues. In this patch series below changes are taken care. 1) Register layout for DME_VS_CORE_CLK_CTRL has changed for v4 and above. 2) Adds Support to configure PA_VS_CORE_CLK_40NS_CYCLES attibute for UFS V4 and above. 3) Adds Support to configure multiple unipro frequencies like 403MHz, 300MHz, 202MHz, 150 MHz, 75Mhz, 37.5 MHz for Qualcomm UFS Controller V4 and above. 4) Allow configuration of SYS1CLK_1US_REG for UFS V4 and above. Changes From v7: - Fix the compilation error for kernel doc Changes from v6: - Addressed bjorn comment to optimize the code. - Addressed bjorn comment to update commit message - removed clean up part related for clk div configuration comapared to v6 changes from v5: - Addressed Mani comment to FIELD_PREP and FIELD_FIT. - Optimised ufs_qcom_set_core_clk_ctrl API. - Updated commit text for few patches to capture more details. Changes from v4: - Addressed bjorn comment to split single patch to multiple patches. Changes from v3: -Addressed bjorn comment to update commit msg to capture change details. Changes from v2: - Addressed bao comment, removed duplicate clock timer cfg API call Changes from v1: - Addressed bao comment, removed wrapper function - Tab alignment Nitin Rawat (5): scsi: ufs: qcom: Update MAX_CORE_CLK_1US_CYCLES for UFS V4 and above scsi: ufs: qcom: Add multiple frequency support for MAX_CORE_CLK_1US_CYCLES scsi: ufs: qcom: Add support to Configure PA_VS_CORE_CLK_40NS_CYCLES scsi: ufs: qcom: Align programing of unipro clk attributes scsi: ufs: qcom: Configure SYS1CLK_1US_REG for UFS V4 and above drivers/ufs/host/ufs-qcom.c | 202 ++++++++++++++++++++++++++++-------- drivers/ufs/host/ufs-qcom.h | 18 +++- 2 files changed, 175 insertions(+), 45 deletions(-) -- 2.17.1
