There are two variants: - 1 GiB or 2 GiB of DDR3 memory - 8 GB or 16 GB eMMC flash Both variants come with: - 802.11 b/g/n wifi (Silicon Valley Microelectronics SSV6051, does not support Bluetooth) - an LED 7 segment display with an FD628 controller - HDMI and AV (CVBS) output - 2x USB (utilizing both USB ports provided by the SoC) - micro SD card slot - serial console (uart_AO) has to be soldered after opening the case The board seems to be very similar to the P23x and Q20x reference boards, which is why it includes meson-gx-p23x-q20x.dtsi: - eMMC reset routed to BOOT_9 - the SDIO wifi chip's reset line is routed to GPIOX_6 and the reference clock is 32.768KHz on PWM_E - SD card detection is routed to CARD_6 - vqmmc of all MMC controllers is hard-wired to 1.8V (VDDIO_BOOT) - uart_AO can be accessed after opening the case and soldering RX, TX and GND lines onto the exposed solder points (marked with RX, TX and GND) Signed-off-by: Martin Blumenstingl --- arch/arm64/boot/dts/amlogic/Makefile | 1 + .../dts/amlogic/meson-gxl-s905w-tx3-mini.dts | 22 +++++++++++++++++++ 2 files changed, 23 insertions(+) create mode 100644 arch/arm64/boot/dts/amlogic/meson-gxl-s905w-tx3-mini.dts diff --git a/arch/arm64/boot/dts/amlogic/Makefile b/arch/arm64/boot/dts/amlogic/Makefile index 6de2e7f5a9cc..1b46affd376d 100644 --- a/arch/arm64/boot/dts/amlogic/Makefile +++ b/arch/arm64/boot/dts/amlogic/Makefile @@ -18,6 +18,7 @@ dtb-$(CONFIG_ARCH_MESON) += meson-gxl-s905x-p212.dtb dtb-$(CONFIG_ARCH_MESON) += meson-gxl-s905d-p230.dtb dtb-$(CONFIG_ARCH_MESON) += meson-gxl-s905d-p231.dtb dtb-$(CONFIG_ARCH_MESON) += meson-gxl-s905w-p281.dtb +dtb-$(CONFIG_ARCH_MESON) += meson-gxl-s905w-tx3-mini.dtb dtb-$(CONFIG_ARCH_MESON) += meson-gxm-khadas-vim2.dtb dtb-$(CONFIG_ARCH_MESON) += meson-gxm-nexbox-a1.dtb dtb-$(CONFIG_ARCH_MESON) += meson-gxm-q200.dtb diff --git a/arch/arm64/boot/dts/amlogic/meson-gxl-s905w-tx3-mini.dts b/arch/arm64/boot/dts/amlogic/meson-gxl-s905w-tx3-mini.dts new file mode 100644 index 000000000000..08aca8346b72 --- /dev/null +++ b/arch/arm64/boot/dts/amlogic/meson-gxl-s905w-tx3-mini.dts @@ -0,0 +1,22 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Copyright (c) 2018 Martin Blumenstingl . + * Based on meson-gxl-s905d-p231.dts: + * - Copyright (c) 2016 Endless Computers, Inc. + * Author: Carlo Caione + */ + +/dts-v1/; + +#include "meson-gxl-s905w.dtsi" +#include "meson-gx-p23x-q20x.dtsi" + +/ { + compatible = "oranth,tx3-mini", "amlogic,s905w", "amlogic,meson-gxl"; + model = "Oranth Tanix TX3 Mini"; + + memory@0 { + device_type = "memory"; + reg = <0x0 0x0 0x0 0x40000000>; /* 1 GiB or 2 GiB */ + }; +}; -- 2.18.0
