In this patch series, added state checker to validate gamma (8BIT and 10BIT).
This reads hardware state, and compares the originally requested state(s/w) to the
state read from the hardware.
This is done for legacy, i965, ilk, glk and their variant platforms.
Intentionally, excluded bdw and ivb since they have spilt gamma mode; for
which degamma read outs are required (which I think shouldn't be included in this
patch series). Will include after degamma state checker is completed.
v1: -Implementation done for legacy platforms
(removed all the placeholders) (Jani)
v2: -Restructured code and created platform specific patch series for
gamma validation
v3: -Rebase
v4: -Minor changes-function name changes mainly
v5: -Added degamma validation (Ville)
v6: -Removed degamma changes, debugging was becoming difficult
-Added function to assign bit_precision for gamma/degamma
lut values /platform
-Added debug info into intel_dump_pipe_config() (Jani)
v7: -Added platform specific functions to compute gamma bit precision
on the basis of GAMMA_MODE (Ville)
-Corrected checkpatch warnings
v8: -Restructured code
-Removed bdw and ivb platform state checker
