[PATCH v3 2/2] ARM: dts: Add exynos5422-odroidxu4 board

Krzysztof Kozlowski k.kozlowski at samsung.com
Sun Sep 13 17:47:49 PDT 2015


Add Hardkernel Odroid XU4 board Device Tree sources. The board differs
from Odroid XU3 and XU3-Lite by:
1. No green and red LEDs (except standard red power LED).
2. Only two PWM outputs are used (fan and blue LED)
3. No audio codec.
4. Two USB3 ports in host mode (no micro USB3 connector for OTG).
5. Realtek RTL8153-CG gigabit network adapter (instead of SMSC9514).
6. Additional connector with IO ports (I2S_0, I2C_5).
7. No DisplayPort (like XU3-Lite).
8. No TI INA231 power measurement sensors (like XU3-Lite).

Changes since v2:
1. Rebase on top v2 "ARM: dts: Fix LEDs on exynos5422-odroidxu3"
   https://lkml.org/lkml/2015/9/13/18
   This means that on new Odroid XU4 DTS the PWM outputs are
   already fixed.
2. Add Javier's reviewed-by.

Changes since v1:
1. hsi2c_5 and is20 are disabled on Odroid XU4 (after moving these nodes
   to the audio DTSI).
2. Update Samsung's copyright date for XU4 DTS.
