Subject: [PATCH v3 2/4] drm/msm/adreno: Add A619 support
Add support for the Adreno 619 GPU, as found in Snapdragon 690 (SM6350),
480 (SM4350) and 750G (SM7225).
Signed-off-by: Konrad Dybcio <konrad.dybcio@...ainline.org>
---
Changes since v2:
- Fix some values in a619_build_bw_table (I think I miscopied things last
time around..)
- Add a comment about icache/dcache allocation for future porters
- Resolve Dmitry's comment about BUG_ON (check patch 1/4)
