Subject: [PATCH v2 2/2] ARM: dts: imx: Add devicetree for Tolino Vison
Add a devicetree for the Tolino Vision Ebook reader. It is based
on boards marked with "37NB-E60Q30+4A3". It is equipped with an i.MX6SL
SoC.
Expected to work:
- Buttons
- Wifi
- LEDs
- uSD
- eMMC
- USB
- RTC
- Touchscreen
- Backlight
