I missed that requirement. I think it's only stated in the i.MX pinctrl bindings that have been converted to YAML. I'll fix the names. Thanks, Jonathan Neuschäfer

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(-) -- 2.28.0
