From: Craig Tatlor <ctatlor97@xxxxxxxxx> Initial device tree support for Qualcomm SDM660 SoC. SDM660 is based off MSM8998 and uses some of its drivers. SDM630/636 are based off SDM660 SoC and they are pin and software compatible. The device tree is based on the CAF 4.4 kernel tree. Features: * CPU nodes * Timer nodes * Interrupt controller * Global Clock Controller * Top Level Mode Multiplexer (pin controller) * UART node This is inspired by and based on the work of Craig Tatlor in https://patchwork.kernel.org/patch/10563667/ Signed-off-by: Craig Tatlor <ctatlor97@xxxxxxxxx> Signed-off-by: Alexey Minnekhanov <alexey.min@xxxxxxxxx> --- arch/arm64/boot/dts/qcom/sdm660.dtsi | 372 +++++++++++++++++++++++++++ 1 file changed, 372 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/sdm660.dtsi b/arch/arm64/boot/dts/qcom/sdm660.dtsi new file mode 100644 index 000000000000..4abbdd03d1e7 --- /dev/null +++ b/arch/arm64/boot/dts/qcom/sdm660.dtsi @@ -0,0 +1,372 @@ +// SPDX-License-Identifier: GPL-2.0-only +/* + * Copyright (c) 2018, Craig Tatlor. + * Copyright (c) 2020, Alexey Minnekhanov <alexey.min@xxxxxxxxx> + */ + +#include <dt-bindings/interrupt-controller/arm-gic.h> +#include <dt-bindings/clock/qcom,gcc-sdm660.h> + +/ { + interrupt-parent = <&intc>;
