[PATCH v6 00/10] drm/bridge: it6505: fix HDCP CTS fail items and add MCCS support
Posted by Hermes Wu via B4 Relay 1 month, 1 week ago
This is a v6 patch-set.

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.

v5->v6:
	-keep the commit message wrapped at 72-75 chars.
	-[10/10] fix return variable being used without being initialized

v4->v5:
	-add more messages for changes.
	-[2/10] modified AUX transfer data size judgment.
		change for-loop to do-while.
	-[7/10] change for-loop to do-while.
	-[9/10] change wait timer with timer_after()

	links:

	https://lore.kernel.org/all/20240926075134.22394-1-Hermes.Wu@ite.com.tw/

v3->v4:
	-split changes  into patches.

v2->v3:
	-split aux read  KSV function to a patch.
	-[1/3] new in v3
	-[2/3] add description of patch

v1->v2:
	- ignored.

I have reviewed the patches that I could review, but I lack deep HDCP
knowledge, so I can not review patches 5, 6, 8, 9. Hopefully somebody
else can step up.

I'm not sure if this requires a re-spin, but you are supposed to
collect the reviewed-by tags you received when you send out a new
version. i.e., put the "Reviewed-by:" lines you received before your
"Signed-off-by:" line.
