From 518d432fd52913c8cb2fe20b140b182f07e0357d Mon Sep 17 00:00:00 2001 From: Yuji Ishikawa Date: Thu, 14 Oct 2021 18:27:03 +0900 Subject: [PATCH] arm64: dts: visconti: Add DTS for the VisROBO board This board consists of two boards: the SoM board (VRC SoM) with the SoC on board, and the board for I/O (VRB). The functions of each board supported by this update are as follows: - VRC SoM - WDT - GPIO - SDCard (SPI-MMC mode) - I2C x1 - VRB board - VRC SoM - UART x2 - Ethernet phy Signed-off-by: Yuji Ishikawa Link: https://lore.kernel.org/r/20211014092703.15251-4-yuji2.ishikawa@toshiba.co.jp Signed-off-by: Nobuhiro Iwamatsu --- arch/arm64/boot/dts/toshiba/Makefile | 1 + .../boot/dts/toshiba/tmpv7708-visrobo-vrb.dts | 61 ++++++++++++++++++++++ .../boot/dts/toshiba/tmpv7708-visrobo-vrc.dtsi | 44 ++++++++++++++++ 3 files changed, 106 insertions(+) create mode 100644 arch/arm64/boot/dts/toshiba/tmpv7708-visrobo-vrb.dts create mode 100644 arch/arm64/boot/dts/toshiba/tmpv7708-visrobo-vrc.dtsi diff --git a/arch/arm64/boot/dts/toshiba/Makefile b/arch/arm64/boot/dts/toshiba/Makefile index 8cd460d..7ccb466 100644 --- a/arch/arm64/boot/dts/toshiba/Makefile +++ b/arch/arm64/boot/dts/toshiba/Makefile @@ -1,2 +1,3 @@ # SPDX-License-Identifier: GPL-2.0 dtb-$(CONFIG_ARCH_VISCONTI) += tmpv7708-rm-mbrc.dtb +dtb-$(CONFIG_ARCH_VISCONTI) += tmpv7708-visrobo-vrb.dtb diff --git a/arch/arm64/boot/dts/toshiba/tmpv7708-visrobo-vrb.dts b/arch/arm64/boot/dts/toshiba/tmpv7708-visrobo-vrb.dts new file mode 100644 index 0000000..d081746 --- /dev/null +++ b/arch/arm64/boot/dts/toshiba/tmpv7708-visrobo-vrb.dts @@ -0,0 +1,61 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Device Tree File for TMPV7708 VisROBO VRB board + * + * (C) Copyright 2020, 2021, Toshiba Corporation. + * (C) Copyright 2020, Nobuhiro Iwamatsu + */ + +/dts-v1/; + +#include "tmpv7708-visrobo-vrc.dtsi" + +/ { + model = "Toshiba TMPV7708 VisROBO (VRB) board"; + compatible = "toshiba,tmpv7708-visrobo-vrb", "toshiba,tmpv7708"; + + aliases { + serial0 = &uart0; + serial1 = &uart1; + }; + + chosen { + stdout-path = "serial0:115200n8"; + }; + + /* 768MB memory */ + memory@80000000 { + device_type = "memory"; + reg = <0x0 0x80000000 0x0 0x30000000>; + }; +}; + +&uart0 { + status = "okay"; + clocks = <&uart_clk>; + clock-names = "apb_pclk"; +}; + +&uart1 { + status = "okay"; + clocks = <&uart_clk>; + clock-names = "apb_pclk"; +}; + +&piether { + status = "okay"; + phy-handle = <&phy0>; + phy-mode = "rgmii-id"; + clocks = <&clk300mhz>, <&clk125mhz>; + clock-names = "stmmaceth", "phy_ref_clk"; + + mdio0 { + #address-cells = <1>; + #size-cells = <0>; + compatible = "snps,dwmac-mdio"; + phy0: ethernet-phy@1 { + device_type = "ethernet-phy"; + reg = <0x1>; + }; + }; +}; diff --git a/arch/arm64/boot/dts/toshiba/tmpv7708-visrobo-vrc.dtsi b/arch/arm64/boot/dts/toshiba/tmpv7708-visrobo-vrc.dtsi new file mode 100644 index 0000000..f0a93db --- /dev/null +++ b/arch/arm64/boot/dts/toshiba/tmpv7708-visrobo-vrc.dtsi @@ -0,0 +1,44 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Device Tree File for TMPV7708 VisROBO VRC SoM + * + * (C) Copyright 2020, 2021, Toshiba Corporation. + * (C) Copyright 2020, Nobuhiro Iwamatsu + */ + +/dts-v1/; + +#include "tmpv7708.dtsi" +#include + +&wdt { + status = "okay"; + clocks = <&wdt_clk>; +}; + +&gpio { + status = "okay"; +}; + +&spi0_pins { + groups = "spi0_grp", "spi0_cs0_grp"; +}; + +&spi0 { + status = "okay"; + clocks = <&clk300mhz>, <&clk150mhz>; + clock-names = "sspclk", "apb_pclk"; + + mmc-slot@0 { + compatible = "mmc-spi-slot"; + reg = <0>; + gpios = <&gpio 15 GPIO_ACTIVE_LOW>; + voltage-ranges = <3200 3400>; + spi-max-frequency = <12000000>; + }; +}; + +&i2c0 { + status = "okay"; + clocks = <&clk150mhz>; +}; -- 2.7.4
