From: Chris Morgan <[email protected]> Add an attribute of "no-hpd" for the Rockchip dw-hdmi-qp controller. This is used to describe implementations where the HPD pin is not connected or used for other purposes, such as in the RK3588S based Gameforce Ace which repurposed the GPIO for an additional face button.
The "no-hpd" option was chosen to be consistent with other devices which already define this parameter for broken or missing hpd functionality.
