Add support for Moxa UC-8410A open platform The UC-8410A computing platform is designed for embedded communication-centric industrial applications The features of UC-8410A are: * QSPI flash * SD slot * 3x LAN * 8x RS-232/422/485 ports, software-selectable * Mini PCIe form factor with PCIe/USB signal * 2x USB host * TPM * Watchdog * RTC * User LEDs * Beeper * Push button Signed-off-by: Jimmy Chen <jimmy.chen@xxxxxxxx> Signed-off-by: Harry YJ Jhou <harryyj.jhou@xxxxxxxx> Signed-off-by: SZ Lin <sz.lin@xxxxxxxx> -- Changes from v1: - Add newline between nodes - Add push button node - Insert newline between property list and child node - Include file of "include/dt-bindings/gpio/gpio.h" - Include file of "include/dt-bindings/input/input.h" - Use polartiy defines for gpios to make it more readable - Put 'status' at the end of property list - Change GPIO pin number in cel_pwr and cel_reset - Sort the labeled node alphabetically - Drop container node of regulator and put fixed regulator directly under root --- arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/ls1021a-moxa-uc-8410a.dts | 241 ++++++++++++++++++++++++++++ 2 files changed, 242 insertions(+) create mode 100644 arch/arm/boot/dts/ls1021a-moxa-uc-8410a.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index d0381e9caf21..62ce9b27ad30 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -520,6 +520,7 @@ dtb-$(CONFIG_SOC_IMX7D) += \ imx7s-colibri-eval-v3.dtb \ imx7s-warp.dtb dtb-$(CONFIG_SOC_LS1021A) += \ + ls1021a-moxa-uc-8410a.dtb \ ls1021a-qds.dtb \ ls1021a-twr.dtb dtb-$(CONFIG_SOC_VF610) += \ diff --git a/arch/arm/boot/dts/ls1021a-moxa-uc-8410a.dts b/arch/arm/boot/dts/ls1021a-moxa-uc-8410a.dts new file mode 100644 index 000000000000..bc73b5187990 --- /dev/null +++ b/arch/arm/boot/dts/ls1021a-moxa-uc-8410a.dts @@ -0,0 +1,241 @@ +/* + * Copyright (C) 2017 Moxa Inc. - https://www.moxa.com/ + * + * Author: Harry YJ Jhou (周亞諄) <harryyj.jhou@xxxxxxxx> + * Jimmy Chen (陳永達) <jimmy.chen@xxxxxxxx> + * SZ Lin (林上智) <sz.lin@xxxxxxxx> + * + * This program is free software;
