drm/i915/icp: Add Interrupt Support
This patch addresses Interrupts from south display engine (SDE).
ICP has two registers - SHOTPLUG_CTL_DDI and SHOTPLUG_CTL_TC.
Introduce these registers and their intended values.
Introduce icp_irq_handler().
The icp_irq_postinstall() takes care of
enabling all PCH interrupt sources, to unmask
them as needed with SDEIMR, as is done
done by ibx_irq_pre_postinstall() for earlier platforms.
We do not need to explicitly call the ibx_irq_pre_postinstall().
Also, while changing these,
s/CPT/PPT/CPT-CNP comment.
v2:
- remove redundant register defines.(Lucas)
- Change register names to be more consistent with
previous platforms (Lucas)
v3:
-Reorder bit defines to a more appropriate location.
Change the comments. Confirm in the commit message that
icp_irq_postinstall() need not go to
ibx_irq_pre_postinstall() and ibx_irq_postinstall()
as in earlier platforms. (Paulo)
