S5P-JPEG support for s5pv210 #14

Closed PabloPL closed 5 years ago

PabloPL commented 6 years ago

It looks like it's missing only dtsi node.

There is some code for testing https://git.linuxtv.org/snawrocki/samsung-utils.git/tree/v4l2-jpeg-codec-test?h=devel&id=487381abe368a430cdfb226cf69f6ba6e2481eff

Done on for-upstream/s5p-jpeg branch.

Patch was accepted on mainline (one adding jpeg node, need to only enable driver in defconfig).
