Subject: [PATCH v2 2/3] ARM: dts: add Netronix E60K02 board common file
Date: Mon, 30 Sep 2019 21:43:31 +0200 [thread overview]
Message-ID: <20190930194332.12246-3-andreas@kemnade.info> (raw)
In-Reply-To: <20190930194332.12246-1-andreas@kemnade.info>
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.
Signed-off-by: Andreas Kemnade <andreas@kemnade.info>

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
