Add support for the newer HDMI-TX (Encoder) v2 and DDC v2 IPs found in MediaTek's MT8195, MT8188 SoC and their variants, and including support for display modes up to 4k60 and for HDMI Audio, as per the HDMI 2.0 spec. HDCP and CEC functionalities are also supported by this hardware, but are not included in this commit and that also poses a slight difference between the V2 and V1 controllers in how they handle Hotplug Detection (HPD). While the v1 controller was using the CEC controller to check HDMI cable connection and disconnection, in this driver the v2 one does not. This is due to the fact that on parts with v2 designs, like the MT8195 SoC, there is one CEC controller shared between the HDMI Transmitter (HDMI-TX) and Receiver (HDMI-RX): before eventually adding support to use the CEC HW to wake up the HDMI controllers it is necessary to have support for one TX, one RX *and* for both at the same time.

Say yes here to enable support for the HDMIv2 IP and related
|
|
DDCv2 as found in the MediaTek MT8195, MT8188 SoCs and other
|
|
variants.
|
|
This driver can also be built as a module. If so, the HDMIv2
|
|
module will be called "mtk_hdmi_v2", and the DDCv2 module
|
|
will be called "mtk_hdmi_ddc_v2".
