Subject: [PATCH 4/4] drm/sun4i: dsi: Add the A100 variant
Date:   Fri, 12 Aug 2022 02:42:56 -0500
Message-Id: <20220812074257.58254-5-samuel@sholland.org>
In-Reply-To: <20220812074257.58254-1-samuel@sholland.org>

Precedence: bulk

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.
