drm/exynos: Check g2d cmd list for g2d restrictions

2013-03-20T10:09:11+00:00

This patch checks command list from user for g2d restrictions.

For now, g2d driver wasn't considered for G2D hardware restrictions
properly. The below is the restrictions to G2D hardware and this patch
considers them.
    - width or height value in the command list
	has to be in valid range (1 to 8000 pixels)
    - The requested area should be less than buffer size.
    - right has to be bigger than left.
    - bottom has to be bigger than top.

Changelog v2:
- Fix merge conflict.

drm/exynos: Fix G2D core malfunctioning issue

2013-03-20T10:09:10+00:00

This patch fixes G2D core malfunctioning issue once g2d dma is started.
Without 'DMA_HOLD_CMD_REG' register setting, there is only one interrupt
after the execution to all command lists have been completed. And that
induces watchdog. So this patch sets 'LIST_HOLD' command to the register
so that command execution interrupt can be occured whenever each command
list execution is finished.

Changelog v2:
- Consider for interrupt setup to each command list and all command lists
  And correct typo.
