Subject: [PATCH v3 07/10] media: dt-bindings: Document i.MX8MQ and i.MX8MM VPU bindings
Date: Fri, 31 May 2019 10:55:20 +0200 [thread overview]
Message-ID: <20190531085523.10892-8-p.zabel@pengutronix.de> (raw)
In-Reply-To: <20190531085523.10892-1-p.zabel@pengutronix.de>
Add devicetree binding documentation for the Hantro G1/G2 VPU on i.MX8MQ
and for the Hantro G1/G2/H1 VPU on i.MX8MM.

+device-tree bindings for Hantro G1/G2/H1 VPU codecs implemented on i.MX8M SoCs
+
+Required properties:
+- compatible: value should be one of the following
+ "nxp,imx8mq-vpu",
+ "nxp,imx8mm-vpu";
+- regs: VPU core and control block register ranges
+- reg-names: should be
+ "g1", "g2", "ctrl" on i.MX8MQ,
+ "g1", "g2", "h1", "ctrl" on i.MX8MM.
+- interrupts: encoding and decoding interrupt specifiers
+- interrupt-names: should be
+ "g1", "g2" on i.MX8MQ,
+ "g1", "g2", "h1" on i.MX8MM.
+- clocks: phandle to VPU core clocks and bus clock
+- clock-names: should be
+ "g1", "g2", "bus" on i.MX8MQ,
+ "g1", "g2", "h1", "bus" on i.MX8MM.
+- power-domains: phandle to power domain node
+
+Examples:
+
+ vpu: vpu@38300000 {
+ compatible = "nxp,imx8mq-vpu";
+ reg = <0x38300000 0x10000>,
+ <0x38310000 0x10000>,
+ <0x38320000 0x10000>;
+ reg-names = "g1", "g2", "ctrl";
+ interrupts = <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>,
+ <GIC_SPI 8 IRQ_TYPE_LEVEL_HIGH>;
+ interrupt-names = "g1", "g2";
+ clocks = <&clk IMX8MQ_CLK_VPU_G1_ROOT>,
+ <&clk IMX8MQ_CLK_VPU_G2_ROOT>,
+ <&clk IMX8MQ_CLK_VPU_DEC_ROOT>;
+ clock-names = "g1", "g2", "bus";
+ power-domains = <&pgc_vpu>;
