This IP, called \"PWMv4\" by Rockchip, introduces\nseveral new features, and consequently differs in its bindings.\n\nInstead of expanding the ever-growing rockchip-pwm binding that already\nhas an if-condition, add an entirely new binding to handle this.\n\nThere are two additional clocks, \"osc\" and \"rc\". These are available for\nevery PWM instance, and the PWM hardware can switch between the \"pwm\",\n\"osc\" and \"rc\" clock at runtime.\n\nThe PWM controller also comes with an interrupt now. This interrupt is\nused to signal various conditions.\n\nReviewed-by: Conor Dooley <conor.dooley@microchip.com>\nReviewed-by: Rob Herring (Arm) <robh@kernel.org>\nSigned-off-by: Nicolas Frattaroli <nicolas.frattaroli@collabora.com>\n---\n .../bindings/pwm/rockchip,rk3576-pwm.yaml | 77 ++++++++++++++++++++++\n MAINTAINERS | 7 ++\n 2 files changed, 84 insertions(+)", "diff": "diff --git a/Documentation/devicetree/bindings/pwm/rockchip,rk3576-pwm.yaml b/Documentation/devicetree/bindings/pwm/rockchip,rk3576-pwm.yaml\nnew file mode 100644\nindex 000000000000..48d5055c8b06\n--- /dev/null\n+++ b/Documentation/devicetree/bindings/pwm/rockchip,rk3576-pwm.yaml\n@@ -0,0 +1,77 @@\n+# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause)\n+%YAML 1.2\n+---\n+$id: http://devicetree.org/schemas/pwm/rockchip,rk3576-pwm.yaml#\n+$schema: http://devicetree.org/meta-schemas/core.yaml#\n+\n+title: Rockchip PWMv4 controller\n+\n+maintainers:\n+ - Nicolas Frattaroli <nicolas.frattaroli@collabora.com>\n+\n+description: |\n+ The Rockchip PWMv4 controller is a PWM controller found on several Rockchip\n+ SoCs, such as the RK3576.\n+\n+ It supports both generating and capturing PWM signals.\n+\n+allOf:\n+ - $ref: pwm.yaml#\n+\n+properties:\n+ compatible:\n+ items:\n+ - const: rockchip,rk3576-pwm\n+\n+ reg:\n+ maxItems: 1\n+\n+ clocks:\n+ items:\n+ - description: Used to derive the PWM signal.\n+ - description: Used as the APB bus clock.\n+ - description: Used as an alternative to derive the PWM signal.\n+ - description: Used as another alternative to derive the PWM signal.\n+\n+ clock-names:\n+ items:\n+ - const: pwm\n+ - const: pclk\n+ - const: osc\n+ - const: rc\n+\n+ interrupts:\n+ maxItems: 1\n+\n+ \"#pwm-cells\":\n+ const: 3\n+\n+required:\n+ - compatible\n+ - reg\n+ - clocks\n+ - clock-names\n+ - interrupts\n+\n+additionalProperties: false\n+\n+examples:\n+ - |\n+ #include <dt-bindings/clock/rockchip,rk3576-cru.h>\n+ #include <dt-bindings/interrupt-controller/arm-gic.h>\n+ #include <dt-bindings/interrupt-controller/irq.h>\n+\n+ soc {\n+ #address-cells = <2>;\n+ #size-cells = <2>;\n+\n+ pwm@2add0000 {\n+ compatible = \"rockchip,rk3576-pwm\";\n+ reg = <0x0 0x2add0000 0x0 0x1000>;\n+ clocks = <&cru CLK_PWM1>, <&cru PCLK_PWM1>, <&cru CLK_OSC_PWM1>,\n+ <&cru CLK_RC_PWM1>;\n+ clock-names = \"pwm\", \"pclk\", \"osc\", \"rc\";\n+ interrupts = <GIC_SPI 102 IRQ_TYPE_LEVEL_HIGH>;\n+ #pwm-cells = <3>;\n+ };\n+ };\ndiff --git a/MAINTAINERS b/MAINTAINERS\nindex 891fb83ba7a9..86f20cb563c6 100644\n--- a/MAINTAINERS\n+++ b/MAINTAINERS\n@@ -23172,6 +23172,13 @@ F:\tDocumentation/userspace-api/media/v4l/metafmt-rkisp1.rst\n F:\tdrivers/media/platform/rockchip/rkisp1\n F:\tinclude/uapi/linux/rkisp1-config.h\n \n+ROCKCHIP MFPWM\n+M:\tNicolas Frattaroli <nicolas.frattaroli@collabora.com>\n+L:\tlinux-rockchip@lists.infradead.org\n+L:\tlinux-pwm@vger.kernel.org\n+S:\tMaintained\n+F:\tDocumentation/devicetree/bindings/pwm/rockchip,rk3576-pwm.yaml\n+\n ROCKCHIP RK3568 RANDOM NUMBER GENERATOR SUPPORT\n M:\tDaniel Golle <daniel@makrotopia.org>\n M:\tAurelien Jarno <aurelien@aurel32.net>\n", "prefixes": [ "v4", "1/5" ] }
