Signed-off-by: Taniya Das --- Changes since V4: - None. Changes since V3: - Use lower case hex. - Check the return value here and bail out early on failure in probe. Changes since V2: - Update the header file name to match the latest upstream header files. Changes since V1: - Use DT indices instead of fw_name. - Replace pm_runtime_enable with devm_pm_runtime_enable. - Change license to GPL from GPL V2. drivers/clk/qcom/Kconfig | 9 + drivers/clk/qcom/Makefile | 1 + drivers/clk/qcom/videocc-sm8450.c | 463 ++++++++++++++++++++++++++++++ 3 files changed, 473 insertions(+) create mode 100644 drivers/clk/qcom/videocc-sm8450.c diff --git a/drivers/clk/qcom/Kconfig b/drivers/clk/qcom/Kconfig index 12be3e2371b3..927aa5983464 100644 --- a/drivers/clk/qcom/Kconfig +++ b/drivers/clk/qcom/Kconfig @@ -962,4 +962,13 @@ config CLK_GFM_LPASS_SM8250 Support for the Glitch Free Mux (GFM) Low power audio subsystem (LPASS) clocks found on SM8250 SoCs. +config SM_VIDEOCC_8450 + tristate "SM8450 Video Clock Controller" + select SM_GCC_8450 + select QCOM_GDSC + help + Support for the video clock controller on Qualcomm Technologies, Inc. + SM8450 devices. + Say Y if you want to support video devices and functionality such as + video encode/decode. endif diff --git a/drivers/clk/qcom/Makefile b/drivers/clk/qcom/Makefile index 9ff4c373ad95..1960ad8e8713 100644 --- a/drivers/clk/qcom/Makefile +++ b/drivers/clk/qcom/Makefile @@ -127,6 +127,7 @@ obj-$(CONFIG_SM_GPUCC_8350) +=3D gpucc-sm8350.o obj-$(CONFIG_SM_TCSRCC_8550) +=3D tcsrcc-sm8550.o obj-$(CONFIG_SM_VIDEOCC_8150) +=3D videocc-sm8150.o obj-$(CONFIG_SM_VIDEOCC_8250) +=3D videocc-sm8250.o +obj-$(CONFIG_SM_VIDEOCC_8450) +=3D videocc-sm8450.o obj-$(CONFIG_SPMI_PMIC_CLKDIV) +=3D clk-spmi-pmic-div.o obj-$(CONFIG_KPSS_XCC) +=3D kpss-xcc.o obj-$(CONFIG_QCOM_HFPLL) +=3D hfpll.o diff --git a/drivers/clk/qcom/videocc-sm8450.c b/drivers/clk/qcom/videocc-s= m8450.c new file mode 100644 index 000000000000..7d0029b8b799 --- /dev/null +++ b/drivers/clk/qcom/videocc-sm8450.c @@ -0,0 +1,463 @@ +// SPDX-License-Identifier: GPL-2.0-only +/* + * Copyright (c) 2023, Qualcomm Innovation Center, Inc.
