Based upon the "Rewrite clk parent handling" series [1] to simplify handling of the external clocks that feed into the MMCC. Assumes the "orphan probe defer" change [2] so that exposing XO via the RPM is safe for the UART in case of late probe per review comments. Assumes the common clk_hw registration is in place from "Make common clk_hw registrations" [3] [1] https://lore.kernel.org/lkml/20190129061021.94775-1-sboyd@kernel.org/T/#u [2] https://lkml.org/lkml/2019/2/11/1895 [3] https://lkml.org/lkml/2019/2/10/132 v2: -Rebased on the "Rewrite clk parent handling" series and updated to the clk init mechanisms introduced there. -Marked XO clk as CLK_IGNORE_UNUSED to avoid the concern about the XO going away "incorrectly" during late init -Corrected the name of the XO clock to "xo" -Dropped the fake XO clock in GCC to prevent a namespace conflict -Fully enumerated the external clocks (DSI PLLs, etc) in the DT binding -Cleaned up the weird newlines in the added DT node -Added DT header file to msm8998 DT for future clients Jeffrey Hugo (4): clk: qcom: smd: Add XO clock for MSM8998 dt-bindings: clock: Add support for the MSM8998 mmcc clk: qcom: Add MSM8998 Multimedia Clock Controller (MMCC) driver arm64: dts: qcom: msm8998: Add mmcc node .../devicetree/bindings/clock/qcom,mmcc.txt | 7 + arch/arm64/boot/dts/qcom/msm8998.dtsi | 15 + drivers/clk/qcom/Kconfig | 9 + drivers/clk/qcom/Makefile | 1 + drivers/clk/qcom/clk-smd-rpm.c | 4 + drivers/clk/qcom/mmcc-msm8998.c | 2937 ++++++++++++++++++++ include/dt-bindings/clock/qcom,mmcc-msm8998.h | 210 ++ 7 files changed, 3183 insertions(+) create mode 100644 drivers/clk/qcom/mmcc-msm8998.c create mode 100644 include/dt-bindings/clock/qcom,mmcc-msm8998.h
