This patch adds IPP subsystem-based gsc driver for exynos5 series.
GSC is stand for General SCaler and supports the following features:
- image scaler/rotator/crop/flip/csc and input/output DMA operations.
- image rotation and image effect functions.
- writeback and display output operations.
- M2M operation to crop, scale, rotation and csc.
The below is GSC hardware path:
Memory------->GSC------>Memory
FIMD--------->GSC------>HDMI
FIMD--------->GSC------>Memory
Memory------->GSC------>FIMD, Mixer
This driver is registered to IPP subsystem framework to be used by user side
and user can control the GSC hardware through some interfaces of IPP subsystem
framework.
