I'm sending this as RFC as I'm not sure this is the right thing to do. There
seems to be a move away from USB specific PHY drivers towards the generic PHY
framework (drivers/phy). The trouble is that my PHY is similar to the mxs PHY
(phy-mxs-usb.c), and like mxs I need the notify_connect/notify_disconnect
callbacks. This functionality is not available is the generic PHY
framework. Having support for both 'usb-phy' and 'phy' properties (as dwc3
seems to do) is particularly bad, since the distinction between the two is a
Linux implementation detail that has nothing to do with hardware description.
So my questions are:
1. Is there a plan to add notifications support to the generic PHY?
2. If not, what are my options?
Thanks,
baruch
