drm/imx/dcss: fix rotations for Vivante tiled formats

2020-12-30T10:53:22+00:00

[ Upstream commit 59cb403f38099506ddbe05fd09126f3f0890860b ] DCSS supports 90/180/270 degree rotations for Vivante tiled and super-tiled formats. Unfortunately, with the current code, they didn't work properly. This simple patch makes the rotations work by fixing the way the scaler is set up for 90/270 degree rotations. In this particular case, the source width and height need to be swapped since DPR is sending the buffer to scaler already rotated. Also, make sure to allow full rotations for DRM_FORMAT_MOD_VIVANTE_SUPER_TILED.

drm/imx: tve remove extraneous type qualifier

2020-10-27T09:30:09+00:00

clang warns about functions returning a 'const int' result: drivers/gpu/drm/imx/imx-tve.c:487:8: warning: type qualifiers ignored on function return type [-Wignored-qualifiers] Remove the extraneous 'const' qualifier here. I would guess that the function was intended to be marked __attribute__((const)) instead, but that would also be wrong since it call other functions without that attribute.

drm/imx: parallel-display: fix edid memory leak

The edid memory is only freed if the component.unbind() is called. This is okay if the parallel-display was bound but if the bind() fails we leak the memory. Signed-off-by: Marco Felsch [p.zabel@pengutronix.de: rebased, dropped now empty unbind()] Signed-off-by: Philipp Zabel
