[Intel-gfx] [PATCH v4] drm/i915: Enable HDCP 1.4 and 2.2 on Gen12+
Ramalingam C
ramalingam.c at intel.com
Tue Jul 9 00:24:15 UTC 2019
>From Gen12 onwards, HDCP HW block is implemented within transcoders.
Till Gen11 HDCP HW block was part of DDI.
Hence required changes in HW programming is handled here.
v2:
_MMIO_TRANS is used [Lucas and Daniel]
platform check is moved into the caller [Lucas]
v3:
platform check is moved into a macro [Shashank]
v4:
Few optimizations in the coding [Shashank]
