Drops code in the probe routine to add xo and sleep_clk. Instead the DTS for the GCC will need to declare both of those clocks for the GCC controller. 2. Supplants parent_names for parent_data for all clocks. 3. Squashes down the previous three patches into two. 4. Drops the git log of copying files. The git log makes clear the silicon is highly similar, so, you can just as easily read the log and do a diff. 5. Doesn't update the MSM8916 with parent_data. Happy to do this at a later date but, don't have the time to validate this properly at the moment. This set focuses on the MSM8939 alone. 6. Dropped comment and boilerplate license text as indicated. 7. Dropped dependency on COMMON_CLK_QCOM seems to not be needed. 8. Easily view the changes here: git add bod https://github.com/bryanodonoghue/linux.git git fetch bod git diff bod/clk-next+msm8939 bod/clk-next+msm8939-v2 V1: These three patches add support for the MSM8939 Global Clock Controller. The MSM8939 is a derivation of the MSM8916 sharing the large majority of its clock settings with MSM8916, however, there are enough changes, in some cases mutually incompatible changes that necessitate a separate driver. I thought it was both important and useful to show in the git log the differences between MSM8916 and MSM8939 so, one patch copies the MSM8916 driver while another patch applies the entire gamut of MSM8939 changes, squashing down from a git log of approximately 31 separate commits. For reference that log is here: https://github.com/bryanodonoghue/linux/pull/new/msm8939-clk-next-reference-log Generally speaking MSM8939 differes from MSM8916 in two key ways. - New and higher clock frequencies for existing IP blocks. - New PLLs to drive those higher frequencies Bryan O'Donoghue (2): clk: qcom: Add DT bindings for MSM8939 GCC clk: qcom: gcc-msm8939: Add MSM8939 Generic Clock Controller .../devicetree/bindings/clock/qcom,gcc.yaml | 3 + drivers/clk/qcom/Kconfig | 8 + drivers/clk/qcom/Makefile | 1 + drivers/clk/qcom/gcc-msm8939.c | 3989 +++++++++++++++++ include/dt-bindings/clock/qcom,gcc-msm8939.h | 206 + include/dt-bindings/reset/qcom,gcc-msm8939.h | 110 + 6 files changed, 4317 insertions(+) create mode 100644 drivers/clk/qcom/gcc-msm8939.c create mode 100644 include/dt-bindings/clock/qcom,gcc-msm8939.h create mode 100644 include/dt-bindings/reset/qcom,gcc-msm8939.h Tested-by: Konrad Dybcio
