This adds a devicetree for the Kobo Aura 2 Ebook reader. It is based on boards marked with "37NB-E60QL0+4B1". It is equipped with an i.MX6SL SoC. Expected to work: - Buttons - Wifi (with external module) - LED - uSD - USB - RTC - Fuel Gauge - Backlight (if the required regulator is probed before the backlight, specifying a supply is not supported by backlightdriver) Signed-off-by: Andreas Kemnade <andreas@kemnade.info> --- Changes in V3: - iomuxc put last - remove hoggrp (vendor kernel/uboot does not touch these things) Changes in V2: - no underscores in node names - fix key/led node names - correct names for pinctl grps arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/imx6sl-kobo-aura2.dts | 556 ++++++++++++++++++++++++ 2 files changed, 557 insertions(+) create mode 100644 arch/arm/boot/dts/imx6sl-kobo-aura2.dts
