I used the same name as used on imx8mq-evk. Do you think a better name
is the one you proposed?

This comes from the linux-imx tree [1]. Nethertheless the reset seems
not to be used by the tpm driver for the infineon chip.

So I think I can remove it here.

Also the usb-hub-reset can be removed.

The whole node is removed since v3.

This comes from the linux-imx tree [2]. but in mainline it is not
valid. So I will remove it.

This comes from the linux-imx tree [3]. but in mainline it is not
valid. So I will remove it.

same as commented before.

Thank you for the review. I will prepare v4.
