v2:
- bring root nodes in alphabetical order
- remove pinctrl_gpio_keys for pciewake
- remove pinctrl_sai2 and pinctrl_spdfif1 since it is not used yet
Thanks to Michael Walle:
- add pinctrl for regulator-v-3v3-sd
- add name for regulator swbst
- add comment about currently unused audio codec
- put usb_phy entry in correct alphabetical order
Thanks to Krzysztof Kozlowski:
- use generic names for pcie-refclk, tpm, fan-controller, sensor
- remove empty line
- fix group name to match schema (ecspi2cs -> ecspi2csgrp)

Same here.

This property is deprecated. Please consider using reset-gpios inside
ethernet-phy instead.

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.

Yes, the way I proposed is the preferred one. Thanks
