[PATCH] ARM: dts: imx25: fix usbhost1 node

[Michael Grzeschik]

The usb port represented by &usbhost1 uses an USB phy internal to the
SoC. We add the phy_type to the base dtsi so the board dts only have to
overwrite it if they use a different configuration. While at it we also
pin the usbhost port to host mode.

Thanks for the ACK.

I just figured out that we also can add the limitation
to maximum-speed = "full-speed" into to dts. Since the
internal phy maximum speed is limited to that.

I will send an v2.

[PATCH v2] ARM: dts: imx25: fix usbhost1 node

[Michael Grzeschik]

The usb port represented by &usbhost1 uses an USB phy internal to the
SoC. We add the phy_type to the base dtsi so the board dts only have to
overwrite it if they use a different configuration. While at it we also
pin the usbhost port to host mode and limit the speed of the phy to
full-speed only, which it is only capable of.

The subject line suggests this is a fix but the commit log and the
actual change don't support this. Maybe better:

	ARM: dts: imx25: consolidate properties of usbhost1 in dtsi file

?

Would it make sense to split this patch in two? One that moves phy_type
and dr_mode from the dts files using imx25.dtsi (which has no effects on
the resulting dtb files). And another that adds maximum-speed.

Best regards
Uwe

And a second patch including the speed limitation change.
