As I understand, already all musb glue platform drivers(dsps/davinci/da8xx) are
changed to new usb_get_phy() API set.
Currently the mainline code snippet as shown.
dsps/davinci/da8xx/xxx_musb_init() {
...
usb_nop_xceiv_register()
..
musb->xceiv = usb_get_phy(USB_PHY_TYPE_USB2);
if (IS_ERR_OR_NULL(musb->xceiv)) {
ret = -EPROBE_DEFER;
goto fail;
}
..
}
Because of this all glue xxx_musb_init() will fail to get the phy without the
phy-bindings for each controller.
Without this patch series am335x musb will fail to get usb_phy(). Similarly phy
support to be added for all davinci/da8xx
platform also. The usb_nop_xciev_xx() is dummy unused API here and hence
removed from all glue in this patch series.
1) dsps platforms (am335x/dm81xx) series uses TI gs70 based phy
This patch adds support for ths dsps phy driver at
drivers/usb/phy/usb-dsps-phy.c
2) omapl13x/da8xx series of soc uses different phy
Separate phy driver need to be added at drivers/usb/phy/usb-da8xx-phy.c
3) similarly all davinci series of soc uses separate TI-phy
Separate phy driver need to added at drivers/usb/phy/usb-davinci-phy.c
The bindings of the respective usb-phy and controller need to done in DT or
non-DT way.
I can add usb-phy support for davinci/da8xx platform in similar way.
