Enable sci0 node using dt overlay and disable can{0,1}-stb-hog nodes in dt overlay as its pins are shared with sci0 pins. Signed-off-by: Biju Das <biju.das.jz@xxxxxxxxxxxxxx> --- v3->v4: * Updated commit header sci0 nodes->sci0 node * Removed PMOD USBUART reference and connection details as user can connect anything on that PMOD1 pins. * Renamed r9a07g043-smarc.dtso->r9a07g043-smarc-pmod.dtso * Dropped unused header file dt-bindings/gpio/gpio.h v3: * New patch --- arch/arm64/boot/dts/renesas/Makefile | 1 + .../dts/renesas/r9a07g043-smarc-pmod.dtso | 42 +++++++++++++++++++ 2 files changed, 43 insertions(+) create mode 100644 arch/arm64/boot/dts/renesas/r9a07g043-smarc-pmod.dtso diff --git a/arch/arm64/boot/dts/renesas/Makefile b/arch/arm64/boot/dts/renesas/Makefile index 23b10c03091c..d1f10ae85f9f 100644 --- a/arch/arm64/boot/dts/renesas/Makefile +++ b/arch/arm64/boot/dts/renesas/Makefile @@ -76,6 +76,7 @@ dtb-$(CONFIG_ARCH_R8A77961) += r8a779m3-ulcb-kf.dtb dtb-$(CONFIG_ARCH_R8A77965) += r8a779m5-salvator-xs.dtb dtb-$(CONFIG_ARCH_R9A07G043) += r9a07g043u11-smarc.dtb +dtb-$(CONFIG_ARCH_R9A07G043) += r9a07g043-smarc-pmod.dtbo dtb-$(CONFIG_ARCH_R9A07G044) += r9a07g044c2-smarc.dtb dtb-$(CONFIG_ARCH_R9A07G044) += r9a07g044l2-smarc.dtb diff --git a/arch/arm64/boot/dts/renesas/r9a07g043-smarc-pmod.dtso b/arch/arm64/boot/dts/renesas/r9a07g043-smarc-pmod.dtso new file mode 100644 index 000000000000..b125a1152982 --- /dev/null +++ b/arch/arm64/boot/dts/renesas/r9a07g043-smarc-pmod.dtso @@ -0,0 +1,42 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * Device Tree Source for the RZ/{G2UL, Five} SMARC EVK PMOD parts + * + * Copyright (C) 2023 Renesas Electronics Corp. + * + * + * [Connection] + * + * SMARC EVK + * +----------------------------+ + * |CN7 (PMOD1 PIN HEADER) | + * | SCI0_TXD pin7 | + * | SCI0_RXD pin8 | + * +----------------------------+ + * + */ + +/dts-v1/; +/plugin/; +#include <dt-bindings/pinctrl/rzg2l-pinctrl.h> + +&pinctrl { + can0-stb-hog { + status = "disabled"; + }; + + can1-stb-hog { + status = "disabled"; + }; + + sci0_pins: sci0-pins { + pinmux = <RZG2L_PORT_PINMUX(2, 2, 5)>, /* TxD */ + <RZG2L_PORT_PINMUX(2, 3, 5)>; /* RxD */ + }; +}; + +&sci0 { + pinctrl-0 = <&sci0_pins>; + pinctrl-names = "default"; + status = "okay"; +}; -- 2.25.1
