Description

Uboot v2024.01 leaves HDMI/VOP and USB ports in a state that is not liked by vendor kernel tools (eg. the Multitool), thus making their usage difficult or impossible.

These patches will assert the resets for HDMI, VOP and USB ports and deassert them on uboot exit, so the kernel (any kernel) will find them in active and "clean" state.

Nerd note: the USB nodes in uboot device tree do not have the reset properties. Adding the reset properties makes the USB ports undetectable to the kernel because uboot - on purpose - leaves the devices with the reset asserted. To let the kernel detect the ports, you have to add the reset properties in the kernel device tree too, so the kernel is able to deassert them. A more complete device tree is not always to be a good thing, for uboot at least.
