[PATCH v2 01/10] media: hantro: Fix H264 max frmsize supported on RK3288
From: Jonas Karlman
Date: Mon Oct 28 2019 - 21:24:54 EST
TRM specify supported image size 48x48 to 4096x2304 at step size 16 pixels,
change frmsize max_width/max_height to match TRM at [1].
This patch makes it possible to decode the 4096x2304 sample at [2].
