Commit Message

Shankar, Uma Jan. 8, 2019, 9:11 a.m.
Hardware may have HDR capability on certain plane
engines. Enabling the same in drm plane structure
so that this can be communicated to user space.

Each drm driver should set this flag to true for planes
which support HDR.

v2: Rebase

I don't see where this is used, am I missing something? You attach the property
to the connector, I don't see how the planes get involved in the end.

Best regards,

Hi Liviu,
Yes currently it's not linked to plane, but I am planning to add a property interface which tells
userspace what underlying hardware planes are capable of HDR. For now, this is not used and
I can drop it to avoid any confusion. Will be sending out the plane capability property for HDR
pretty soon (most probably along with next version of this series).

Regards,
Uma Shankar
