Subject: [PATCH v7 00/10] drm/bridge: it6505: fix HDCP CTS fail items and
 add MCCS support

There are lots of failure items while running HDCP CTS using UNIGRAF DPR-100.
In Order to fix those failures, HDCP flow needs to be changed.

The DisplayPort AUX protocol supports I2C transport.
In Order to support MCCS via the aux channel, the aux-i2c operation is added.
