[PATCH v6, 00/15] Using component framework to support multi hardware decode

[Yunfei Dong]

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 1~3 rewrite get register bases and power on/off interface.

Patch 4 add component framework to support multi hardware.

Patch 5 separate video encoder and decoder document

Patches 6-15 add interfaces to support core hardware.
----
This patch dependents on : "media: mtk-vcodec: support for MT8183 decoder"[1] and
"Mediatek MT8192 clock support"[2].

1: Multi hardware decode is based on stateless decoder, MT8183 is the first time
to add stateless decoder. Otherwise it will cause conflict. This patch will be
accepted in 5.15[1].

2: The definition of decoder clocks are in mt8192-clk.h, this patch already in clk tree[2].

  Fix platform_set_drvdata.
- Fix build error for patch 9/15
- Add depend patch in case of error header file for patch 13/15

Changes compared with v3:
- Fix return value for patch 1/15
- Fix comments for patch 4/15
  > Looking up "mediatek,mtk-vcodec-core" to determine if it uses component framwork sounds like...
  Add prameter in pdata, for all platform will use compoent after mt8183

  Must call component_master_add_with_match after platform_set_drvdata for component architecture.
- Fix yaml files check fail for patch 5/15
- Fix yaml file check fail for patch 14/15

Changes compared with v1:
- Fix many comments for patch 3/14
- Remove unnecessary code for patch 4/14
- Using enum mtk_vdec_hw_count instead of magic numbers for patch 6/14
- Reconstructed get/put lat buffer for lat and core hardware for patch 7/14
- Using yaml format to instead of txt file for patch 12/14
