In addition to GCC this driver is also responsible for providing MDSS and GFX3D clocks which reside in the same register space. SoMainline is dedicated to getting their long-awaited msm8976 support, including the Xperia X, X Compact and if feasible also the Xperia Touch projector (APQ8056) slowly but steadily upstreamed. Changes since v5: - Set vdd_gfx-supply in yaml example, which was added as required property in v5 but forgotten from the example; this is only caught by running dt_binding_check in addition to dtbs_check. v5: https://lore.kernel.org/linux-clk/20211004195255.701220-1-marijn.suijten@somainline.org/T Changes since v4: - Insert error handling that left `int ret;` in gcc_msm8976_probe unused when the original regmap read, xor, and write were replaced with regmap_update_bits in v3; - Document vdd_gfx supply, required in oxili_gx_gdsc; - Dual-license the yaml Documentation and DT bindings (Rob). Changes since v3: - Set the enable_mask of gcc_apss_ahb_clk and gcc_apss_axi_clk to BIT 14 and 13 respectively instead of overlapping gcc_crypto_ahb_clk's BIT 0. Changes since v2: - Rebased on v5.14; - Various minor cleanups (lowercase hex, const where appropriate, removal of unused enum constants); - Fixed XOR confusion in probe; - All remnants of global clock name dependencies are removed, all inter-driver dependencies must be fully specified in DT; - Added proper dt-bindings yaml validation, listing the required clocks; - Moved dt-bindings header to the dt-bindings patch. Changes since v1: - Rebased onto linux-next 20191015 - Fixed platform driver name (qcom,gcc-8976 => gcc-msm8976) - Splitted changes to dt-bindings to a separate commit AngeloGioacchino Del Regno (1): clk: qcom: Add MSM8976/56 Global Clock Controller (GCC) driver Marijn Suijten (1): dt-bindings: clk: qcom: Document MSM8976 Global Clock Controller .../bindings/clock/qcom,gcc-msm8976.yaml | 97 + drivers/clk/qcom/Kconfig | 8 + drivers/clk/qcom/Makefile | 1 + drivers/clk/qcom/gcc-msm8976.c | 4160 +++++++++++++++++ include/dt-bindings/clock/qcom,gcc-msm8976.h | 240 + 5 files changed, 4506 insertions(+) create mode 100644 Documentation/devicetree/bindings/clock/qcom,gcc-msm8976.yaml create mode 100644 drivers/clk/qcom/gcc-msm8976.c create mode 100644 include/dt-bindings/clock/qcom,gcc-msm8976.h base-commit: 0fcfb00b28c0b7884635dacf38e46d60bf3d4eb1 -- 2.34.1
