From f71a5c88666dc642c428abcc5d58c1362aba5050 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Mon, 5 Oct 2020 11:24:02 +0200 Subject: ARM: dts: i.MX8MQ: Add Cortex-M4 Coprocessor node The i.MX8MQ has a Cortex-M4 Coprocessor. Add a node for controlling it. To make use of it the board has to provide the reserved memory nodes, for example: reserved-memory { #address-cells = <2>; #size-cells = <2>; ranges; m4_reserved: m7@0x40000000 { no-map; reg = <0 0x40000000 0 0x1000000>; }; m4_reserved_sysmem3: rproc@80000000 { reg = <0 0x80000000 0 0x800000>; no-map; }; }; &remoteproc_cm4 { memory-region = <&m4_reserved>, <&m4_reserved_sysmem3>; }; Signed-off-by: Sascha Hauer --- arch/arm/dts/imx8mq.dtsi | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'arch/arm') diff --git a/arch/arm/dts/imx8mq.dtsi b/arch/arm/dts/imx8mq.dtsi index 5f2df35bc9..ec8347f38f 100644 --- a/arch/arm/dts/imx8mq.dtsi +++ b/arch/arm/dts/imx8mq.dtsi @@ -4,6 +4,14 @@ * Copyright (C) 2017 Pengutronix, Lucas Stach */ +/ { + remoteproc_cm4: remoteproc-cm4 { + compatible = "fsl,imx8mq-cm4"; + clocks = <&clk IMX8MQ_CLK_M4_CORE>; + syscon = <&src>; + }; +}; + &clk { assigned-clocks = <&clk IMX8MQ_CLK_USDHC1>, <&clk IMX8MQ_CLK_USDHC2>, -- cgit v1.2.3
