[RFC v2 0/4] Crystal Cove PMIC based Panel and Backlight Control

[Shobhit Kumar <shobhit.kumar@intel.com>]

Hi All
Please find modifed set of patches. Sending as a separate thread as initial
patches were a crude implementation to trigger discussion, but these have been 
tested and also do not need intel_soc_pmic_writeb/readb functionaly, but uses
the regmap interface as suggested by Jacob.

These patches implement a drm_panel as a platform driver for the mfd_cell device
declared in intel_soc_pmic_core.c. 

Still there are opens, where I need closure - 
1. Added a new drm_panel, but how to find the panel in lack of OF info. For now
   added a drm_panel function to find panel by name.
2. Backlight also needs similar pmic based control. Is it okay to add a backlight
   class driver also as part of this panel driver ?

For now I am doing Backlight Enable/Disable also during panel/enable as this will
at least save power. Backlight control will need a backlight class driver.

Regards
Shobhit
