Shankar, Uma June 1, 2021, 10:41 a.m. UTC
Introduced a client cap for advance cap mode capability. Userspace
should set this to get to be able to use the new gamma_mode property.

If this is not set, driver will work in legacy mode.

Note: This is suggested by Ville and based on his idea, the new
gamma mode handling is designed.

Typo: "cap mode" should be "gamma mode"?

"advance" is a verb. Did you mean "advanced"?
