Subject: [PATCH 2/5] drm/panel: simple: Set bpc from bits-per-color DT property for panel-dpi
Date: Tue, 14 Jul 2020 15:13:02 +0800	[thread overview]
Message-ID: <20200714071305.18492-3-wens@kernel.org> (raw)
In-Reply-To: <20200714071305.18492-1-wens@kernel.org>

From: Chen-Yu Tsai <wens@csie.org>

Now that the device tree binding for panel-dpi has the "bits-per-color"
property, parse its value and set bpc in the panel description to the
given value. This would allow encoders to detect less-than-8-bits color
depth and employ color dithering if possible.
