For now, the only visible differences compared to the board stack are: - The SoC is an updated version of R-Car V4H (R8A779G0), - The serial console uses an FT2232H instead of a CP2102 USB-UART bridge, with CTS/RTS wired. Signed-off-by: Geert Uytterhoeven Reviewed-by: Wolfram Sang --- v2: - Add Reviewed-by, - Refer to hscif0_pins directly, - Add SoC name to top-level comment. --- arch/arm64/boot/dts/renesas/Makefile | 2 ++ .../renesas/r8a779g2-white-hawk-single.dts | 26 +++++++++++++++++++ 2 files changed, 28 insertions(+) create mode 100644 arch/arm64/boot/dts/renesas/r8a779g2-white-hawk-single.dts diff --git a/arch/arm64/boot/dts/renesas/Makefile b/arch/arm64/boot/dts/renesas/Makefile index b959ae4a586bf8f7..1d7d69657a1f0559 100644 --- a/arch/arm64/boot/dts/renesas/Makefile +++ b/arch/arm64/boot/dts/renesas/Makefile @@ -87,6 +87,8 @@ dtb-$(CONFIG_ARCH_R8A779G0) += r8a779g0-white-hawk-ard-audio-da7212.dtbo r8a779g0-white-hawk-ard-audio-da7212-dtbs := r8a779g0-white-hawk.dtb r8a779g0-white-hawk-ard-audio-da7212.dtbo dtb-$(CONFIG_ARCH_R8A779G0) += r8a779g0-white-hawk-ard-audio-da7212.dtb +dtb-$(CONFIG_ARCH_R8A779G0) += r8a779g2-white-hawk-single.dtb + dtb-$(CONFIG_ARCH_R8A77951) += r8a779m1-salvator-xs.dtb r8a779m1-salvator-xs-panel-aa104xd12-dtbs := r8a779m1-salvator-xs.dtb salvator-panel-aa104xd12.dtbo dtb-$(CONFIG_ARCH_R8A77951) += r8a779m1-salvator-xs-panel-aa104xd12.dtb diff --git a/arch/arm64/boot/dts/renesas/r8a779g2-white-hawk-single.dts b/arch/arm64/boot/dts/renesas/r8a779g2-white-hawk-single.dts new file mode 100644 index 0000000000000000..2f79e5a6124897ef --- /dev/null +++ b/arch/arm64/boot/dts/renesas/r8a779g2-white-hawk-single.dts @@ -0,0 +1,26 @@ +// SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +/* + * Device Tree Source for the R-Car V4H ES2.0 White Hawk Single board + * + * Copyright (C) 2023 Glider bv + */ + +/dts-v1/; +#include "r8a779g2.dtsi" +#include "white-hawk-cpu-common.dtsi" +#include "white-hawk-common.dtsi" + +/ { + model = "Renesas White Hawk Single board based on r8a779g2"; + compatible = "renesas,white-hawk-single", "renesas,r8a779g2", + "renesas,r8a779g0"; +}; + +&hscif0 { + uart-has-rtscts; +}; + +&hscif0_pins { + groups = "hscif0_data", "hscif0_ctrl"; + function = "hscif0"; +};
