[PATCH 00/20] drm/i915/dp: Fix few SST HPD IRQ handling issues

[Imre Deak]

This patchset fixes a few HPD IRQ handling issues on SST links and
makes the SST and MST IRQ handling code more unified.

Imre Deak (20):
  drm/i915/dp_mst: Reprobe connector if the IRQ ESI read failed
  drm/i915/dp_mst: Verify the link status always the same way
  drm/i915/dp_mst: Reuse intel_dp_check_link_state() in the HPD IRQ
    handler
  drm/i915/dp: Handle a tunneling IRQ after acking it
  drm/i915/dp: Handle the RX_CAP_CHANGED HPD IRQ
  drm/i915/dp: Handle the DOWNSTREAM_PORT_STATUS_CHANGED event
  drm/i915/dp: Don't clobber the encoder state in the HPD IRQ handler
  drm/i915/dp: Remove the device service IRQ handling from connector
    detect
  drm/i915/dp: Fix the device service IRQ DPCD_REV check
  drm/i915/dp: Fix the link service IRQ DPCD_REV check
  drm/i915/dp: Reprobe connector if getting/acking device IRQs fails
  drm/i915/dp: Reprobe connector if getting/acking link service IRQs
    fails
  drm/i915/dp: Return early if getting/acking device service IRQs fails
  drm/i915/dp: Return early if getting/ackink link service IRQs fails
  drm/i915/dp: Read/ack sink count and sink IRQs for SST as it's done
    for MST
  drm/i915/dp: Print debug message for a sink connected off request
  drm/i915/dp: Check SST link status while handling link service IRQs
  drm/i915/dp_mst: Reuse intel_dp_handle_link_service_irq()
  drm/i915/dp: Ack only the handled device service IRQs
  drm/i915/dp: Ack only the handled link service IRQs
