Subject: [PATCH 1/2] dt-bindings: leds: register-bit-led: Add value property
Date: Wed, 6 Jul 2022 13:28:27 +0200 [thread overview]
Message-ID: <20220706112828.27278-1-pali@kernel.org> (raw)
Allow to define inverted logic (0 - enable LED, 1 - disable LED) via value
property. This property name is already used by other syscon drivers, e.g.
syscon-reboot.
