[CABC PATCH 0/2] CABC patch list

2016-03-01 Thread Deepak M
CABC stands for the Content Adaptive Backlight Control.
In the normal display the backlight which we see is due to the
backlight which is being modulated by the filter, which is inturn
dependent on the image. In brief the CABC does the histogram
analysis of the image and then controls the filter and backlight.
For example in CABC to display the dark image the backlight is dimmed
and then controlls the filter to allow more light, because of
which is power consuption will be reduced.

Below are the initial set of patches which supports the CABC.
A field exits in the mipi configuration of the VBT which
when enabled indiactes the CABC is supported. Depending on
this filed the backlight control function pointer are
initialized in the intel_panel.c file.

In case of dual link panels depending on the panel
the DCS commands have to be send to either PORT A,
PORT C or both PORT A and PORT C. Again a filed is
added in the VBT to get this data from the version 197 onwards.
One of the below patches parses these fields from the
VBT.

Addressed the review comments of Jani, which were mentioned in
