This is my first time looking at dts handling in drivers, so I might
be completely wrong, but I am thinking that since the controller node
links to the phy node, so the controller node is the parent of the phy
node, so if there is an of api can look it up?
If the phy is a child of the controller, then yes this would work,
but in the case of sunxi the phy is a built-in mmio mapped peripheral
just like the controller, so they sit at the same level and have no
parent child relation.
musb_dsps dts is the same.
sun8i-a33.dtsi:
soc {
usb_otg: {
phys = <&usbphy 0>;
}
usbphy: {
}
}
As in the example above, usb_otg node refers to usbphy node, so I am
wondering if there is an of api to look up the usb_otg properties in
the usbphy driver.
That would boil down to hardcoding the node name / path compatible
which is not acceptable from a devicetree pov.
Really having to duplicate the dr_mode is not that bad / such big
a deal.
