[PATCH v2 0/2] Enable_psr kernel parameter changes

[Jouni Högander]

Currently disabling PSR2 via enable_psr module parameter causes Panel
Replay being disabled as well. This patch changes this by still allowing
Panel Replay even if PSR2 is disabled.

After this patch enable_psr module parameter values are:

-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
 3 = PSR1 : yes, PSR2 = no,  Panel Replay : no

I.e. values different than -1 and 0 are handled as bitmasks where BIT0
disables PSR2 and BIT1 disables Panel Replay. Enable_psr parameter
doesn't impact Early Transport anymore.

v2:
  - make it more clear that enable_psr is bitmask for disabling different
    PSR modes

Jouni Högander (2):
  drm/i915/psr: Do not disable Early Transport when enable_psr is set
  drm/i915/psr: Do not disable Panel Replay if PSR2 is disabled
