Subject: [PATCH 4/6] drm: bridge: samsung-dsim: Dynamically configure DPHY timing
Date:   Sat, 15 Apr 2023 05:41:01 -0500
Message-Id: <20230415104104.5537-4-aford173@gmail.com>
In-Reply-To: <20230415104104.5537-1-aford173@gmail.com>

NXP uses a lookup table to determine the various values for
the PHY Timing based on the clock rate in their downstream
kernel.  Since the input clock can be variable, the phy
settings need to be variable too.  Add an additional variable
to the driver data to enable this feature to prevent breaking
boards that don't support it.
