From 655ef9f9e87568aff031391712669b74d1b362f1 Mon Sep 17 00:00:00 2001 From: Michael Tretter Date: Thu, 3 Dec 2020 12:01:02 +0100 Subject: media: allegro: add helper to get entropy mode The driver only supports CAVLC for H.264, but HEVC only uses CABAC. As the driver has to explicitly tell the MCU to use CABAC for HEVC, add a helper function to get the entropy mode.
