These clocks and resets could be used by DMA, VIN and Display modules. Patches 1 and 2 are about the System-Top-Group clock and reset generator(STGCRG) part. The first patch adds docunmentation to describe STG bindings, and the second patch adds clock driver to support STG clocks and resets as auxiliary device for JH7110. Patches 3 and 4 are about the Image-Signal-Process clock and reset gennerator(ISPCRG) part. The first patch adds docunmentation to describe ISP bindings, and the second patch adds clock driver to support ISP clocks and resets as auxiliary device for JH7110. And ISP clocks should power on and enable the SYSCRG clocks first before registering. Patches 5 and 6 are about the Video-Output clock and reset generator(VOUTCRG) part. The first patch adds docunmentation to describe VOUT bindings, and the second patch adds clock driver to support VOUT clocks and resets as auxiliary device for JH7110. And VOUT clocks also should power on and enable the SYSCRG clocks first before registering. Patch 7 adds struct members to support STG/ISP/VOUT resets. Patch 8 adds external clocks which ISP and VOUT clock driver need. Patch 9 adds device node about STGCRG, ISPCRG and VOUTCRG to JH7110 dts. Changes since v6: - Rebased on the Linux 6.5-rc1. - Dropped the unnecessary selections in the Kconfig. - Dropped the patches about the PMU node and MAINTIANERS. - Add the reviews. v6: https://lore.kernel.org/all/20230518101234.143748-1-xingyu.wu@starfivetech.com/ Changes since v5: - Rebased on the Linux 6.4-rc2. - Modified the reset name about VOUTCRG to fix the error with CONFIG_FORTIFY_SOURCE=y - Added the patch about pmu node. v5: https://lore.kernel.org/all/20230424135409.6648-1-xingyu.wu@starfivetech.com/ Changes since v4: - Rebased on the lastest patches about fixing the basic clock and reset drivers. - Dropped the 'dev_set_drvdata()' in STG clock driver. - Modified the data with 'dev_set_drvdata()' in ISP/VOUT clock driver and move the struct about the data to JH7110 header file, which both ISP and VOUT clock drivers will use. v4: https://lore.kernel.org/all/20230411135558.44282-1-xingyu.wu@starfivetech.com/ Changes since v3: - Rebased on the lastest JH71X0 clock and reset driver of patchset[1] and modified the parameters of the register reset functions. - The patch 1 combined three commits on STG/ISP/VOUT resets into one. And Changed the auxiliary_device_id name from "clk_starfive_jh71x0.reset-*" to "clk_starfive_jh7110_sys.rst-*". - Added a maintainer in STARFIVE JH71X0 CLOCK DRIVERS. v3: https://lore.kernel.org/all/20230314124404.117592-1-xingyu.wu@starfivetech.com/ Changes since v2: Patch 1: - Dropped the modification of maintainers. - Modified clock and reset names in the dt-bindings header files. Patch 3: - Added 'Emil Renner Berthing' as the author. - Used 'default m' in Kconfig file. - Changed the flags of 'CLK_IGNORE_UNUSED' to 0 or 'CLK_IS_CRITICAL'. Patch 4: - Dropped the 'reset-names' property. - Shortened the clock and reset names in the dt-bindings header files. Pacth 6: - Used 'default m' in Kconfig file. - Changed the flags of 'CLK_IGNORE_UNUSED' to 0. - Set reset_control struct to a local variable because it just is used one time in probe. Pacth 7: - Dropped the 'reset-names' property. Patch 9: - Used 'default m' in Kconfig file. - Set reset_control struct to a local variable because it just is used one time in probe. Patch 10: - Changed the order of externel clock in alphanumerical order. Patch 11: - Dropped the 'reset-names' property in ispcrg and voutcrg node. v2: https://lore.kernel.org/all/20230221083323.302471-1-xingyu.wu@starfivetech.com/ Changes since v1: - Modified the binding and dropped the indentation. - Removed the useless header files in the drivers. - Used an array lookup instead of a pile of conditions about parent clocks' name. - Added clocks operation on driver remove. v1: https://lore.kernel.org/all/20230120024445.244345-1-xingyu.wu@starfivetech.com/ Emil Renner Berthing (1): clk: starfive: Add StarFive JH7110 System-Top-Group clock driver Xingyu Wu (8): dt-bindings: clock: Add StarFive JH7110 System-Top-Group clock and reset generator dt-bindings: clock: Add StarFive JH7110 Image-Signal-Process clock and reset generator clk: starfive: Add StarFive JH7110 Image-Signal-Process clock driver dt-bindings: clock: Add StarFive JH7110 Video-Output clock and reset generator clk: starfive: Add StarFive JH7110 Video-Output clock driver reset: starfive: jh7110: Add StarFive STG/ISP/VOUT resets support riscv: dts: starfive: jh7110: Add DVP and HDMI TX pixel external clocks riscv: dts: starfive: jh7110: Add STGCRG/ISPCRG/VOUTCRG nodes .../clock/starfive,jh7110-ispcrg.yaml | 87 +++++++ .../clock/starfive,jh7110-stgcrg.yaml | 82 ++++++ .../clock/starfive,jh7110-voutcrg.yaml | 90 +++++++ .../jh7110-starfive-visionfive-2.dtsi | 8 + arch/riscv/boot/dts/starfive/jh7110.dtsi | 67 +++++ drivers/clk/starfive/Kconfig | 24 ++ drivers/clk/starfive/Makefile | 3 + .../clk/starfive/clk-starfive-jh7110-isp.c | 232 +++++++++++++++++ .../clk/starfive/clk-starfive-jh7110-stg.c | 173 +++++++++++++ .../clk/starfive/clk-starfive-jh7110-vout.c | 239 ++++++++++++++++++ drivers/clk/starfive/clk-starfive-jh7110.h | 6 + .../reset/starfive/reset-starfive-jh7110.c | 30 +++ .../dt-bindings/clock/starfive,jh7110-crg.h | 74 ++++++ .../dt-bindings/reset/starfive,jh7110-crg.h | 60 +++++ 14 files changed, 1175 insertions(+) create mode 100644 Documentation/devicetree/bindings/clock/starfive,jh7110-ispcrg.yaml create mode 100644 Documentation/devicetree/bindings/clock/starfive,jh7110-stgcrg.yaml create mode 100644 Documentation/devicetree/bindings/clock/starfive,jh7110-voutcrg.yaml create mode 100644 drivers/clk/starfive/clk-starfive-jh7110-isp.c create mode 100644 drivers/clk/starfive/clk-starfive-jh7110-stg.c create mode 100644 drivers/clk/starfive/clk-starfive-jh7110-vout.c Acked-by: Palmer Dabbelt
