drm/mediatek: fix OF sibling-node lookup

2018-11-13T19:08:54+00:00

commit ceff2f4dcd44abf35864d9a99f85ac619e89a01d upstream. Use the new of_get_compatible_child() helper to lookup the sibling instead of using of_find_compatible_node(), which searches the entire tree from a given start node and thus can return an unrelated (i.e. non-sibling) node. This also addresses a potential use-after-free (e.g. after probe deferral) as the tree-wide helper drops a reference to its first argument (i.e. the parent device node). While at it, also fix the related cec-node reference leak.

treewide: Replace more open-coded allocation size multiplications

2018-10-06T01:06:30+00:00

As done treewide earlier, this catches several more open-coded allocation size calculations that were added to the kernel during the merge window. This performs the following mechanical transformations using Coccinelle: kvmalloc(a * b, ...) -> kvmalloc_array(a, b, ...) kvzalloc(a * b, ...) -> kvcalloc(a, b, ...) devm_kzalloc(..., a * b, ...) -> devm_kcalloc(..., a, b, ...)

drm/mediatek: update some variable name from ovl to comp

2018-08-27T03:24:37+00:00

This patch update some variable name from ovl to comp Because RDMA would be first HW in ddp, the naming ovl should be change to comp. Signed-off-by: Stu Hsieh Signed-off-by: CK Hu

drm/mediatek: use layer_nr function to get layer number to init plane

2018-08-27T03:24:37+00:00

This patch use layer_nr function to get layer number to init plane When plane init in crtc create, it use the number of OVL layer to init plane. That's OVL can read 4 memory address. For mt2712 third ddp, it use RDMA to read memory. RDMA can read 1 memory address, so it just init one plane. For compatibility, this patch use mtk_ddp_comp_layer_nr function to get layer number from their HW component in ddp for plane init. Signed-off-by: Stu Hsieh Signed-off-by: CK Hu
