+ROCKCHIP USB2.0 PHY WITH INNO IP BLOCK
+
+Required properties (phy (parent) node):
+ - compatible : should be one of the listed compatibles:
+ * "rockchip,rk3366-usb2phy"
+ * "rockchip,rk3399-usb2phy"
+ - #clock-cells : should be 0.
+ - clock-output-names : specify the 480m output clock name.
+
+Optional properties:
+ - clocks : phandle + phy specifier pair, for the input clock of phy.
+ - clock-names : input clock name of phy, must be "phyclk".
+ - vbus_host-supply : phandle to a regulator that supplies host vbus.
+ - vbus_otg-supply : phandle to a regulator that supplies otg vbus.
Nit: s/_/-/ here.
Something I only stumbled over yesterday for the first time on my rk3288-
popmetal: The phy subnodes seem to be able to use a generic phy-supply
property from inside the phy-core itself, see:
https://github.com/mmind/linux-rockchip/commit/93739f521fc65f44524b00c9aaf6db46bca94e02#diff-ddf3e45ebb753d6debf57022003a1a57R597
for my WIP code for that other board.
Ah, good comments! I will try later, if it is practicable, I shall correct it
into the next patches (patch v4).
I am sorry to tell you that seems unworkable, because we have two sub-nodes
(phy-ports) in one parent-node (phy),
what is more, the 'phy-supply' property can only put into parent-node, I
believe it can not be differentiated types of ports.
'phy-supply' is a property of the phy node and not the 'phy-provider' node. So
IMO this should work. What problem do you see?
Sorry, I think I must have made a wrong phandle of phy-port name in
*.dts before.
Yes, It works now, thanks for your reminding.
@Heiko,
I have just received your another mail, thanks again for your detail
explanation.
I will correct it in the next patches (patch v4).
BR.
Frank
