[PATCH (repost) 2/5] drm_dp_cec: add note about good MegaChips 2900 CEC support

From: Hans Verkuil <hans.verkuil at cisco.com> A big problem with DP CEC-Tunneling-over-AUX is that it is tricky to find adapters with a chipset that supports this AND where the manufacturer actually connected the HDMI CEC line to the chipset. Add a mention of the MegaChips 2900 chipset which seems to support this feature well.

[PATCH 0/5] drm/nouveau+amdgpu: add DP CEC-Tunneling-over-AUX

...#39;s the first time I ever looked at amdgpu code. Two notes on CEC-Tunneling-over-AUX: 1) You need to be very careful about which USB-C/DP/mini-DP to HDMI adapters you buy. Only a few support this feature correctly today. Known chipsets that support this are Parade PS175 & PS176 and MegaChips 2900. Unfortunately almost all Parade-based adapters do not hook up the HDMI CEC pin to the chip, making them useless for this. The Parade reference design was only recently changed to hook up this pin, so perhaps this situation will change for new Parade-based adapters. Adapters ba...
