Subject: [PATCH] drm/rockchip: vop2: clear afbc en and transform bit for
|
|
cluster window at linear mode
|
|
|
|
The enable bit and transform offset of cluster windows should be
|
|
cleared when it work at linear mode, or we may have a iommu fault
|
|
issue on rk3588 which cluster windows switch between afbc and linear
|
|
mode.
|
|
|
|
As the cluster windows of rk3568 only supports afbc format
|
|
so is therefore not affected.
