From: Hermes Wu <Hermes.wu@ite.com.tw> This is a v5 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. 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/20240926074755.22176-4-Hermes.Wu@ite.com.tw/ 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.
