Adding a debugfs entry for detecting the valid HDCP sinks to
perform kms_content_protection.

In case of dummy HDMI/DP sinks(EDID whisperers without any parsers)
IGT will skip the HDCP test on that connector instead of failing it.
Hence false alarm are avoided.

For serving above purpose this series has pulled out few changes
from "Implement HDCP2.2" series under review at
https://patchwork.freedesktop.org/series/38254/

"drm/i915: hdcp_check_link only on CP_IRQ" is just a improvement
patch for HDCP1.4. Already received the reviewed-by from Sean Paul.

v4:
  Squashed patch #2 into #4.
  Pulled the conn_to_dig_port into intel_drv.h

Ramalingam C (3):
  drm/i915: Pullout the bksv read and validation
  drm/i915: hdcp_check_link only on CP_IRQ

All these dmesg warnings are there because of the sink in CI which doesn't support hdcp registers. Which is expected in case of dummy HDMI sinks.
So we could go ahead and merge these patches.

DMESG-WARN is not allowed for any test, so the patch is currently
unacceptable. Please simply report that the sync does not support HDCP
in i915_hdcp_sink_capability, but no warnings are allowed in dmesg.

In Linux, we put the cost of integration on the person writing the
patch. Thus, if you need to rework the internals of i915 to achieve a
warning-free dmesg log, you will be expected to do so, so as not to
regress anything.

Looking forward to seeing an updated patch :)

PS: The retry button should not be pressed lightly as it steals machine
time from other tasks. If you believe some noise might just have
happened and blocked the testing of your patch series, please contact me
to file a bug in our suppression system (CI Bug Log) *before* being
allowed to press the button.

Thanks Martin, for pointing it out. These errors were part of authentication we have.
New patches are using a routine from auth flow hence when DDC request fail caused these errors.
As I had a closure with danvet, I will move these errors to debug level.

Agreed. At first attempt to request retest I saw that without result update,
re-queued for test state was gone. So clicked couple of times.
I remember this mistake next time. :)

DMESG-WARN is not allowed for any test, so the patch is currently
unacceptable. Please simply report that the sync does not support HDCP
in i915_hdcp_sink_capability, but no warnings are allowed in dmesg.

In Linux, we put the cost of integration on the person writing the
patch. Thus, if you need to rework the internals of i915 to achieve a
warning-free dmesg log, you will be expected to do so, so as not to
