Hi All
Please find modifed set of patches using regmap interface to accedd the PMIC 
registers. These patches implement a drm_panel as a platform driver for the
mfd_cell device declared in intel_soc_pmic_core.c. 

DRM is extended to provide a find panel by name in absence of OF. 

Backlight control is pending. For now I am doing Backlight Enable/Disable also
during panel/enable as this will at least save power.


Shobhit Kumar (4):
  drm: Add support to find drm_panel by name
  mfd: Add a new cell device for panel controlled by crystal cove pmic
  drm/i915: Add new panel driver based on crystal cove pmic
  drm/i915: Enable DSI panel enable/disable based on PMIC
