Messages in this thread Patch in this message | | | From | Jonathan Neuschäfer <> | Subject | [PATCH v3 7/7] ARM: dts: imx50-kobo-aura: Add Netronix embedded controller | Date | Fri, 25 Sep 2020 07:08:18 +0200 |
| |
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> ---
v3: - Remove interrupt-controller property from embedded-controller node - subnodes of embedded-controller node in to the main node
v2: - https://lore.kernel.org/lkml/20200905144503.1067124-3-j.neuschaefer@gmx.net/ - Fix pwm-cells property (should be 2, not 1) --- arch/arm/boot/dts/imx50-kobo-aura.dts | 17 ++++++++++++++++- 1 file changed, 16 insertions(+), 1 deletion(-)
