+Subject: [PATCH 1/2] drm/sun4i: Fix mipi-dsi panel framerate being 2/3 of the
+ expected value
+
+This happens on Pinephone and on Pinetab. Both use MIPI-DSI panels.
+
+On Pinephone framerate is 36.6 instead of expected 55.
+On Pinetab the similar 2/3 ratio holds.
+
+Myabe there's a bug in BSP and dclk_div should really be 6 instead of 4.
