Subject: [PATCH v2 4/4] drm/sun4i: dsi: Add the A100 variant
Date:   Sun,  6 Nov 2022 23:35:52 -0600
Message-Id: <20221107053552.2330-5-samuel@sholland.org>
In-Reply-To: <20221107053552.2330-1-samuel@sholland.org>

The A100 variant of the MIPI DSI controller now gets its module clock
from the TCON via the TCON TOP, so the clock rate cannot be set to a
fixed value. Otherwise, it appears to be the same as the A31 variant.
