The i.MX8MQ has a Cortex-M7 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; m7_reserved_sysmem1: rproc@40000000 { reg = <0 0x40000000 0 0x800000>; no-map; }; m7_reserved_sysmem2: rproc@40800000 { reg = <0 0x40800000 0 0x800000>; no-map; }; m7_reserved_sysmem3: rproc@80000000 { reg = <0 0x80000000 0 0x800000>; no-map; }; }; &remoteproc_cm7 { memory-region = <&m7_reserved_sysmem1>, <&m7_reserved_sysmem2>, <&m7_reserved_sysmem3>; }; Signed-off-by: Sascha Hauer <s.hauer@xxxxxxxxxxxxxx> --- arch/arm/dts/imx8mp-evk.dts | 1 + arch/arm/dts/imx8mp.dtsi | 9 +++++++++ 2 files changed, 10 insertions(+) create mode 100644 arch/arm/dts/imx8mp.dtsi diff --git a/arch/arm/dts/imx8mp-evk.dts b/arch/arm/dts/imx8mp-evk.dts index bb255e2c94..3264ade4b8 100644 --- a/arch/arm/dts/imx8mp-evk.dts +++ b/arch/arm/dts/imx8mp-evk.dts @@ -7,6 +7,7 @@ /dts-v1/; #include <arm64/freescale/imx8mp-evk.dts> +#include "imx8mp.dtsi" / { chosen { diff --git a/arch/arm/dts/imx8mp.dtsi b/arch/arm/dts/imx8mp.dtsi new file mode 100644 index 0000000000..b251ebeada --- /dev/null +++ b/arch/arm/dts/imx8mp.dtsi @@ -0,0 +1,9 @@ +// SPDX-License-Identifier: (GPL-2.0 OR MIT) + +/ { + remoteproc_cm7: remoteproc-cm7 { + compatible = "fsl,imx8mp-cm7"; + clocks = <&clk IMX8MP_CLK_M7_CORE>; + syscon = <&src>; + }; +}; -- 2.28.0 _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
