The APIs are returning correctly the err codes, no need to assign -EIO
to the ret again.

Use the wrapper function for getting the driver data using lcd_device
instead of using dev_get_drvdata with &ld->dev, so we can directly pass a

use of_node_put() on it when done.

Add mmp display subsystem to support Marvell MMP display controllers.
This subsystem contains 4 parts:
--fb folder
--core.c
--hw folder
--panel folder
1. fb folder contains implementation of fb. fb get path and overlay
from common interface and operates on these structures.
2. core.c provides common interface for a hardware abstraction. Major
parts of this interface are:
a) Path: path is a output device connected to a panel or HDMI TV. Main
operations of the path is set/get timing/output color. fb operates
output device through path structure.
b) Ovly: Ovly is a buffer shown on the path.
Ovly describes frame buffer and its source/destination size, offset,
input color, buffer address, z-order, and so on. Each fb device maps
to one overlay.
3. hw folder contains implementation of hardware operations defined by
core.c. It registers paths for fb use.
4. panel folder contains implementation of panels. It's connected to
path. Panel drivers would also regiester panels and linked to path
when probe.
