Subject: [PATCH] drm/vc4: Correct handling of rotation parameter in
|
||
|
|
fkms
|
||
|
|
|
||
|
|
One bit within DRM_MODE_ROTATE_MASK will always be set to
|
||
|
|
determine the base rotation 0/90/180/270, and then REFLECT_X
|
||
|
|
and REFLECT_Y are on top.
|
||
|
|
|
||
|
|
Correct the handling which was assuming that REFLECT_[X|Y]
|
||
|
|
was instead of ROTATE_x.
|
||
|
|
