Subject: [PATCH] media: uapi: Add hevc ctrls for WPP decoding
WPP can allow greater parallelism within the decode, but needs
offset information to be passed in.
Adds num_entry_point_offsets and entry_point_offset_minus1 to
v4l2_ctrl_hevc_slice_params.
This is based on Jernej Skrabec's patches for cedrus which
implement the same feature.
