This patchset adds:
 - (Generic) integrated privacy screen support in drm
 - Ability in i915 to attach to ACPI nodes
 - an implmentation for ACPI privacy screen in i915

Rajat Jain (4):
  intel_acpi: Rename drm_dev local variable to dev
  drm/connector: Add support for privacy-screen property
  drm/i915: Lookup and attach ACPI device node for connectors
  drm/i915: Add support for integrated privacy screen

Add support for generic electronic privacy screen property, that
can be added by systems that have an integrated EPS.

Signed-off-by: Rajat Jain <rajatja@google.com>

v7: * Initial version, formed by moving the privacy-screen property into
      drm core.
    * Break the init_property() into create_property() and attach_property()
      so that property can be created while registering connector, but
      attached in late_register() (after ACPI node detection).

Lookup and attach ACPI nodes for intel connectors. The lookup is done
in compliance with ACPI Spec 6.3
https://uefi.org/sites/default/files/resources/ACPI_6_3_final_Jan30.pdf
(Ref: Pages 1119 - 1123).

This can be useful for any connector specific platform properties. (This
will be used for privacy screen in next patch).

Signed-off-by: Rajat Jain <rajatja@google.com>
---
v7: Look for ACPI node in ->late_register() hook.
    Do the scan only once per drm_device (instead of 1 per drm_connector)
v6: Addressed minor comments from Jani at
    https://lkml.org/lkml/2020/1/24/1143
     - local variable renamed.
     - used drm_dbg_kms()
     - used acpi_device_handle()
     - Used opaque type acpi_handle instead of void*
v5: same as v4
v4: Same as v3
v3: fold the code into existing acpi_device_id_update() function
v2: formed by splitting the original patch into ACPI lookup, and privacy
    screen property. Also move it into i915 now that I found existing code
    in i915 that can be re-used.

Add support for an ACPI based integrated privacy screen that is
available on some systems.

Signed-off-by: Rajat Jain <rajatja@google.com>
---
v7: * Move the privacy-screen property back into drm core.
    * Do the actual HW EPS toggling at commit time.
    * Provide a sample ACPI node for reference in comments. 
v6: Always initialize prop in intel_attach_privacy_screen_property()
v5: fix a cosmetic checkpatch warning
v4: Fix a typo in intel_privacy_screen.h
v3: * Change license to GPL-2.0 OR MIT
    * Move privacy screen enum from UAPI to intel_display_types.h
    * Rename parameter name and some other minor changes.
v2: Formed by splitting the original patch into multiple patches.
    - All code has been moved into i915 now.
    - Privacy screen is a i915 property
    - Have a local state variable to store the prvacy screen. Don't read
      it from hardware.

+ * drm connector device with the following elements:
+ *
+ * UUID should be "c7033113-8720-4ceb-9090-9d52b3e52d73"

+ * Pages 1119 - 1123.
+ *
+ * _DSM method that will perform the following functions according to
+ * Local1 argument passed to it:
+ *  - Local1 = 0 (EPS capabilities): Report EPS presence and capabilities.
+ *  - Local1 = 1 (EPS State)  :  _DSM returns 1 if EPS is enabled, 0 otherwise.
+ *  - Local1 = 2 (EPS Enable) :  _DSM enables EPS
+ *  - Local1 = 3 (EPS Disable):  _DSM disables EPS
+ *

For my testing purposes, I'm testing this using the proptest userspace utility
in our distribution (I think from
https://github.com/CPFL/drm/blob/master/tests/proptest/proptest.c). I
notice that when I change the value of the property from userspace,
even though the drm_connector_state->privacy_screen_status gets
updated and reflects the change, the encoder->update_pipe() is not
getting called. Just wanted to ask if this is expected since you seem
to have implied that this update_pipe() might *not* get called if there *is* a
full modeset? (What is the hook that gets called for a full modeset
where i915 driver should commit this property change to the hardware?)

Thanks a lot for all your help,

Best Regards,

Rajat

Kind ignore, I found the answer, and posted my new patchset here:
https://patchwork.freedesktop.org/series/74607/

I got a "failed to apply" email from the patchwork. Can you please let
me know on which branch is it trying to apply it? I have currently
rebased my patchset to drm-intel-next-queued.

Thanks & Best Regards,

Rajat
