[v1,00/14] Using component framework to support multi hardware decode

Message

Yunfei Dong July 7, 2021, 6:21 a.m. UTC

This series adds support for multi hardware decode into mtk-vcodec, by first
adding component framework to manage each hardware information: interrupt,
clock, register bases and power. Secondly add core thread to deal with core
hardware message, at the same time, add msg queue for different hardware
share messages. Lastly, the architecture of different specs are not the same,
using specs type to separate them.

This series has been tested with both MT8183 and MT8173. Decoding was working
for both chips.

Patches 1,2 rewrite get register bases and power on/off interface.

Patch 3-5 add component framework to support multi hardware.

Patches 6-14 add interfaces to support core hardware.
----
This patch dependents on "media: mtk-vcodec: support for MT8183 decoder"[1].

Multi hardware decode is based on stateless decoder, MT8183 is the first
time to add stateless decoder. Otherwise it will cause conflict.
Please also accept this patch together with [1].
