A lot of functionality is still missing: - poweroff/reboot, RTC, and battery monitoring support, as well as a PWM channel for the display backlight are provided by a custom embedded controller, which will be supported by a future patchset. The EC driver will also tell the EC to keep the board powered on; otherwise the EC will power the board off after about ten seconds (presumably to avoid battery drain if the OS is missing or corrupted) - The touchscreen controller, eKTF2132, currently doesn't have a mainline driver. - The e-paper display controller (EPDC) embedded in the i.MX50 SoC will need a whole new DRM driver, devicetree bindings, etc. - The TPS65185 PMIC, which generates the voltages necessary for driving the E Ink panel, also needs a driver - The backlight doesn't quite fit the existing pwm-backlight DT binding, because it uses an additional GPIO to boost the brightness. This requires some devicetree work - Linux doesn't currently support suspend-to-ram on i.MX50 In order to keep the system running when CONFIG_PM is enabled, the following fix is also required: https://lore.kernel.org/lkml/20190326182258.21945-1-j.neuschaefer@gmx.net/ My own notes about this machine can be found here: https://github.com/neuschaefer/linux/wiki/Kobo-Aura Jonathan Neusch=C3=A4fer (3): dt-bindings: Add vendor prefix for Rakuten Kobo, Inc. dt-bindings: arm: fsl: Add i.MX50 based boards ARM: dts: imx50: Add Kobo Aura DTS .../devicetree/bindings/arm/fsl.yaml | 7 + .../devicetree/bindings/vendor-prefixes.txt | 1 + arch/arm/boot/dts/Makefile | 3 +- arch/arm/boot/dts/imx50-kobo-aura.dts | 258 ++++++++++++++++++ 4 files changed, 268 insertions(+), 1 deletion(-) create mode 100644 arch/arm/boot/dts/imx50-kobo-aura.dts =2D- 2.20.1
