The Netronix board E60K02 can be found some several Ebook-Readers,
at least the Kobo Clara HD and the Tolino Shine 3. The board
is equipped with different SoCs requiring different pinmuxes.
For now the following peripherals are included:
- LED
- Power Key
- Cover (gpio via hall sensor)
- RC5T619 PMIC (the kernel misses support for rtc and charger
subdevices).
- Backlight via lm3630a
- Wifi sdio chip detection (mmc-powerseq and stuff)
It is based on vendor kernel but heavily reworked due to many
changed bindings.

Changes in v4:
- style cleanup, non-legacy wakeup-source
- remove pinmux-* properties
Changes in v3:
- better led name
- correct memory size
- comments about missing devices
Changes in v2:
- reordered, was 1/3
- moved pinmuxes to their actual users, not the parents
of them
- removed some already-disabled stuff
- minor cleanups

Should have a newline here. I fixed it up and applied the patch.
