[PATCH v5 5/8] media: mediatek: vcodec: fix vp9 4096x2176 fail for profile2
From: Kyrie Wu
Date: Thu Nov 06 2025 - 01:13:36 EST
The dram addr of vp9 decoder tile number, which use dram mode
to set tile information, may reach to 36bits for 4096x2176.
It needs to get the highest 4bit of tile buffer address to
set tile buffer address.
Fixes: 5d418351ca8f1 ("media: mediatek: vcodec: support stateless VP9 decoding")
