Subject: [PATCH v2 10/10] ARM: dts: imx50-kobo-aura: Add Netronix embedded controller
Date: Sat,  5 Sep 2020 16:45:02 +0200	[thread overview]
Message-ID: <20200905144503.1067124-3-j.neuschaefer@gmx.net> (raw)
In-Reply-To: <20200905133230.1014581-1-j.neuschaefer@gmx.net>

Enable the Netronix EC on the Kobo Aura ebook reader.

Several features are still missing:
 - Frontlight/backlight. The vendor kernel drives the frontlight LED
   using the PWM output of the EC and an additional boost pin that
   increases the brightness.
 - Battery monitoring
 - Interrupts for RTC alarm and low-battery events

Signed-off-by: Jonathan Neuschäfer <j.neuschaefer@gmx.net>

v2:
- Fix pwm-cells property (should be 2, not 1)
