Subject: [PATCH 1/2] dt-bindings: pwm-backlight: Add 'max-brightness' property
Date: Mon, 10 Jun 2019 16:37:38 -0700 [thread overview]
Message-ID: <20190610233739.29477-1-mka@chromium.org> (raw)
Add an optional 'max-brightness' property, which is used to specify
the number of brightness levels (max-brightness + 1) when the node
has no 'brightness-levels' table.
