This clock controller feeds the Multimedia Display SubSystem (MDSS). It's a porting of dispcc-scuba GPL-2.0 driver from CAF msm-4.19 kernel: https://source.codeaurora.org/quic/la/kernel/msm-4.19/tree/drivers/clk/qcom/dispcc-scuba.c?h=LE.UM.4.4.1.r3 Global clock name references (parent_names) have been replaced by parent_data and parent_hws. Clocks marked enable_safe_config have their clk_rcg2_ops moved to clk_rcg2_shared_ops. Signed-off-by: Loic Poulain --- v2: Added missing dispcc-qcm2290.h header file v3: - Moved dt-bindings header into dt bindings commit - clk_rcg2_ops to clk_rcg2_shared_ops for enable_safe_config marked clocks. v4: - Removed useless NOCACHE clk flags - Added explicit comment for OPS_PARENT_ENABLE flag - Removed useless headers (clk.h, reset.h) - spark_vco tab as const - removed global .name reference for sleep_clk - removed dispcc_xo_clk as it is always on (enabled in probe) - removed dev_info message on probe success - Kconfig: Select QCM_GCC_2290 for builtin v5: Remove unused PI_CORE_BI_PLL_TEST_SE source drivers/clk/qcom/Kconfig | 9 + drivers/clk/qcom/Makefile | 1 + drivers/clk/qcom/dispcc-qcm2290.c | 555 ++++++++++++++++++++++++++++++++++++++ 3 files changed, 565 insertions(+) create mode 100644 drivers/clk/qcom/dispcc-qcm2290.c diff --git a/drivers/clk/qcom/Kconfig b/drivers/clk/qcom/Kconfig index 42c8741..f5b54bf 100644 --- a/drivers/clk/qcom/Kconfig +++ b/drivers/clk/qcom/Kconfig @@ -340,6 +340,15 @@ config QCM_GCC_2290 Say Y if you want to use multimedia devices or peripheral devices such as UART, SPI, I2C, USB, SD/eMMC etc. +config QCM_DISPCC_2290 + tristate "QCM2290 Display Clock Controller" + select QCM_GCC_2290 + help + Support for the display clock controller on Qualcomm Technologies, Inc + QCM2290 devices. + Say Y if you want to support display devices and functionality such as + splash screen. + config QCS_GCC_404 tristate "QCS404 Global Clock Controller" help diff --git a/drivers/clk/qcom/Makefile b/drivers/clk/qcom/Makefile index 0d98ca9..d96d679 100644 --- a/drivers/clk/qcom/Makefile +++ b/drivers/clk/qcom/Makefile @@ -56,6 +56,7 @@ obj-$(CONFIG_QCOM_CLK_RPM) += clk-rpm.o obj-$(CONFIG_QCOM_CLK_RPMH) += clk-rpmh.o obj-$(CONFIG_QCOM_CLK_SMD_RPM) += clk-smd-rpm.o obj-$(CONFIG_QCM_GCC_2290) += gcc-qcm2290.o +obj-$(CONFIG_QCM_DISPCC_2290) += dispcc-qcm2290.o obj-$(CONFIG_QCS_GCC_404) += gcc-qcs404.o obj-$(CONFIG_QCS_Q6SSTOP_404) += q6sstop-qcs404.o obj-$(CONFIG_QCS_TURING_404) += turingcc-qcs404.o diff --git a/drivers/clk/qcom/dispcc-qcm2290.c b/drivers/clk/qcom/dispcc-qcm2290.c new file mode 100644 index 00000000..96b1493 --- /dev/null +++ b/drivers/clk/qcom/dispcc-qcm2290.c @@ -0,0 +1,555 @@ +// SPDX-License-Identifier: GPL-2.0-only +/* + * Copyright (c) 2020, The Linux Foundation.
