Subject: [PATCH V2 1/3] dt-bindings: display: mediatek: Update disp_aal binding for MT8183
Date: Mon, 11 Apr 2022 11:58:41 +0800	[thread overview]
Message-ID: <20220411035843.19847-2-rex-bc.chen@mediatek.com> (raw)
In-Reply-To: <20220411035843.19847-1-rex-bc.chen@mediatek.com>

The driver data of MT8183 and MT8173 are different.

For MT8173, the gamma module is inside disp_aal. When we need to adjust
gamma value, we need to use "has_gamma" to control gamma function
inside disp_aal to adjust the gamma value.

For successors like MT8183, disp_gamma is separated from disp_aal. We
just need to control disp_gamma directly and don't need to control gamma
function inside disp_aal.

With this modification, the driver doesn't require any functional changes.
We only update the dt-binding and DTS node to make it clear.
