Sylwester Nawrocki a7d5bbcf9c [media] s5p-fimc: Add suport for FIMC on S5PC210 SoCs
Enable FIMC operation on S5PC210 (S5PV310) SoCs. This a minimal
adaptation to obtain functionality of older FIMC IP revisions
(S5PC100, S5PC110) on S5PC210 SOcs.

Sylwester Nawrocki 548aafcd9e [media] s5p-fimc: mem2mem driver refactoring and cleanup
Register access functions refactored for camera capture interface
control. Removed the workqueue since it was only useful for FIFO
output mode which is not supported at this time.
Fixed errors on module unload. Comments and whitespace cleanup.
