It is designed to be mounted on carrier boards, enabling the development of complete embedded systems. Purwa uses a slightly different Iris HW revision (8.1.2 on Hamoa, 8.1.11 on Purwa). Support will be added later. Make the following peripherals on the SOM enabled: - Regulators on the SOM - Reserved memory regions - PCIe3, PCIe4, PCIe5, PCIe6a - USB0 through USB6 and their PHYs - ADSP, CDSP - Graphic Signed-off-by: Yijie Yang Reviewed-by: Konrad Dybcio --- .../qcom/{hamoa-iot-som.dtsi =3D> purwa-iot-som.dtsi} | 11 +++++------ 1 file changed, 5 insertions(+), 6 deletions(-) copy arch/arm64/boot/dts/qcom/{hamoa-iot-som.dtsi =3D> purwa-iot-som.dtsi}= (99%) diff --git a/arch/arm64/boot/dts/qcom/hamoa-iot-som.dtsi b/arch/arm64/boot/= dts/qcom/purwa-iot-som.dtsi similarity index 99% copy from arch/arm64/boot/dts/qcom/hamoa-iot-som.dtsi copy to arch/arm64/boot/dts/qcom/purwa-iot-som.dtsi index b8e3e04a6fbd..fb90beb1096f 100644 --- a/arch/arm64/boot/dts/qcom/hamoa-iot-som.dtsi +++ b/arch/arm64/boot/dts/qcom/purwa-iot-som.dtsi @@ -3,11 +3,14 @@ * Copyright (c) Qualcomm Technologies, Inc. and/or its subsidiaries. */ =20 -#include "hamoa.dtsi" +#include "purwa.dtsi" #include "hamoa-pmics.dtsi" #include #include =20 +/delete-node/ &pmc8380_6; +/delete-node/ &pmc8380_6_thermal; + / { reserved-memory { linux,cma { @@ -378,16 +381,12 @@ vreg_l3j_0p8: ldo3 { }; }; =20 -&iris { - status =3D "okay"; -}; - &gpu { status =3D "okay"; }; =20 &gpu_zap_shader { - firmware-name =3D "qcom/x1e80100/gen70500_zap.mbn"; + firmware-name =3D "qcom/x1p42100/gen71500_zap.mbn"; }; =20 &pcie3 { --=20 2.34.1
