Subject: [PATCH 230/351] 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.
