+Subject: [PATCH] DSS2: Check fclk limits when configuring video planes
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf-8
+Content-Transfer-Encoding: 8bit
+
+Check that the currect functional clock is fast enough to support
+the requested scaling ratios. Also check if 5-tap filtering can be
+used even though the downscaling ratio is less than 1:2 since the
+functional clock rate required for 5-tap filtering can be less than
+the requirement for 3-tap filtering, and 5-tap filtering should look
+better.

+Subject: [PATCH] DSS2: pass the default FB color format through board info
+
+Add a field to the FB memory region platform data, so that board
+init code can pass a default color format to the driver. Set this
+format as an initial setting for the given FB.
+
+This is needed for an upcoming patch that adds detection of the
+color format set by the bootloader.
