This patch set enables the HDMI port on the Lenovo ThinkBook 16 G7 QOY. 
The definitions have been derived from the T14s device tree, with some
necessary changes. The HDMI bridge seems to utilize the enable pin. 
The required GPIO was derived from the AeoB dump of the Windows GPU 
driver. 

Since the qmpphy involved is usb_1_ss2_qmpphy, and that usb_1_ss2 block 
is also used to operate the fingerprint reader, there's some possible
interference. The explicit port configuration on usb_1_ss2_dwc3 minimizes
this, however it works more reliable with the pipe_clk patch [1] that 
is discussed. Booting with HDMI cable cold-plugged results in the 
fingerprint reader not enumerating. Hot-plug and suspend doesn't kill it,
though.
