Subject: [PATCH RESEND v6 2/2] leds: ktd2692: Make aux-gpios optional
Date:   Wed,  4 May 2022 18:04:11 +0300
Message-Id: <20220504150457.5626-3-markuss.broks@gmail.com>

Make the AUX pin optional, since it isn't a core part of functionality,
and the device is designed to be operational with only one CTRL pin.

Also pick up maintenance for the LED driver and the yaml bindings.
