[V1,0/6] Support multi-hardware jpeg decoding using of_platform_populate

Message

Kyrie Wu (吴晗) Dec. 3, 2021, 5:34 a.m. UTC

This series adds support for multi hardware jpeg decoding,
by first adding use of_platform_populate to manage each hardware
information: interrupt, clock, register bases and power.
Secondly add decoding work queue to deal with the decoding requests
of multi-hardware at the same time. Lastly, add output picture
reorder function interface to eliminate the out of order images.

This series has been tested with both MT8195.
Decoding worked for this chip.

Patches 1~2 use of_platform_populate to manage multi-hardware.

Patch 3 add jpeg decoding timeout function to judge hardware timeout.

Patch 4 add decoding work queue to deal with multi-hardware decoding
at the same time.

Patch 5 add output picture reorder function to order images.

Patch 6 refactor jpegdec func interface for HW working.
