Subject: [PATCH] adjustment out of
|
|
setup_clipping_and_scaling()
|
|
|
|
The offset adjustment depends on the framebuffer modified, so let's
|
|
just move this operation in the DRM_FORMAT_MOD_LINEAR case inside
|
|
vc4_plane_mode_set().
|
|
|
|
This we'll be able to fix offset calculation for
|
|
DRM_FORMAT_MOD_BROADCOM_VC4_T_TILED and DRM_FORMAT_MOD_BROADCOM_SANDXXX.
