This does not have any compatible string, so this can-control block
should be removed.

reg should come right after compatible.

This gives a warning as rx8025 does not exist.

It should be "epson,rx8025" instead.

pinctrl_usdhc1_gpio is not being used as you only pass pinctrl-names =
"default". Remove pinctrl_usdhc1_gpio.

pinctrl_usdhc2_gpio is not being used as you only pass pinctrl-names =
"default". Remove pinctrl_usdhc2_gpio.

Please add blank lines to separate the pinctrl groups.
