can you check how similar the rk3588-orangepi--5-max is to the
already existing orangepi-5-plus please?

For rk3588s-orangepi-5 and orangepi-5b we already have this nicely
shared dtsi for commit things, and somehow I assume this might be
similar for 5-plus vs 5-max.

preferred pattern for fixed-regulator nodenames is regulator-......

Same for the othe fixed regulators below.

please make that one comment block and use appropriate formatting

/*
 * Represents the vcc5v0_usb20 and vcc5v0_usb30 in the schematic,
 * both regulators share the same enable gpio
 */

what does this comment try to explain? If that is the name of the pin,
just name the pinctrl below accordingly (instead of hym8563_int
if applicable) .

this needs to be "default" to actually work
