From 35f51f6091bcf2cb90d9ac2f41465c415a34632e Mon Sep 17 00:00:00 2001 From: Benjamin Gaignard Date: Thu, 3 Jun 2021 13:50:01 +0200 Subject: media: uapi: Add a control for HANTRO driver The HEVC HANTRO driver needs to know the number of bits to skip at the beginning of the slice header. That is a hardware specific requirement so create a dedicated control for this purpose.
