From: Fabio Estevam <redacted> Add the initial RV1103B devicetree. Based on the 5.10 Rockchip vendor kernel. Signed-off-by: Fabio Estevam <redacted> --- Changes since v5: - Remove unneeded x32k oscillator. - Sort the nodes without address unit. - Remove bootph-all. - Pass a more specific watchdog compatible. .../boot/dts/rockchip/rv1103b-pinctrl.dtsi | 816 ++++++++++++++++++ arch/arm/boot/dts/rockchip/rv1103b.dtsi | 249 ++++++ 2 files changed, 1065 insertions(+) create mode 100644 arch/arm/boot/dts/rockchip/rv1103b-pinctrl.dtsi create mode 100644 arch/arm/boot/dts/rockchip/rv1103b.dtsidiff --git a/arch/arm/boot/dts/rockchip/rv1103b-pinctrl.dtsi b/arch/arm/boot/dts/rockchip/rv1103b-pinctrl.dtsi new file mode 100644 index 000000000000..539d4d9510c1 --- /dev/null +++ b/arch/arm/boot/dts/rockchip/rv1103b-pinctrl.dtsi@@ -0,0 +1,816 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Copyright (c) 2024 Rockchip Electronics Co., Ltd.
