[PATCH v2 0/3] drm/i915/dmc_wl: Track pipe interrupt registers

[Gustavo Sousa]

>Pipe interrupt registers live in their respective pipes' power wells,
>which are below PG0. That means that they must also be tracked as
>registers that are powered-off during dynamic DC states.
>
>For that, we first convert the display IRQ code to use display-specific
>MMIO functions so that DMC wakelock checks are properly done and then
>add the range for pipe interrupts in the table checked by the DMC
>wakelock code.
>
>This series fixes vblank timeouts that were happening due to PIPE
>interrupt registers being accessed without the DMC wakelock.
>
>v2:
> - Change "drm/i915/display: Wrap IRQ-specific uncore functions" to have
>   the wrappers as static functions inside intel_display_irq.c.
