[PATCH v4 0/4] drm/layerscape: Add Freescale DCU DRM driver

[Jianwei Wang]

@Daniel,
Do you have any other comments for this driver?

@Stefan,
Please help test this driver on vybrid if possible, I have test it on vybrid twr board.

If anyone has any objections, please let me know.

Changed in V4:
-This version doesn't have functionality changed. Just a minor adjustment.

Changed in V3:
- Test driver on Vybrid board and add compatible string
- Remove unused functions
- set default crtc for encoder
- replace legacy functions with atomic help functions
- Set the unique name of the DRM device
- Implement irq handle function for vblank interrupt

Changed in v2:
- Add atomic support
- Modify bindings file
- Rename node for compatibility
- Move platform related code out for compatibility

Added in v1:
- Add support for DCU display controller on the Freescale LS102x SoCs.
- Create a primary plane, a fb created for fbdev, a crtc, a connector for TFT LCD panel, an encoder.
