Currently setting enable_psr kernel parameter to != -1 is disabling Panel Replay and Early Transport. This patch set is changing enable_psr meaning as follows:
-1 = PSR1 : yes, PSR2 = yes, Panel Replay : yes 0 = PSR1 : no, PSR2 = no, Panel Replay : no 1 = PSR1 : yes, PSR2 = no, Panel Replay : yes 2 = PSR1 : yes, PSR2 = yes, Panel Replay : no I.e. 1 disables PSR2 and 2 disables Panel replay. 0 disables PSR/Panel Replay completely. Enable_psr parameter doesn't impact Early Transport anymore.
