Subject: [PATCH 0/2] usb: add HCD providers
Date: Tue, 12 Jul 2016 14:35:18 +0200 [thread overview]
Message-ID: <1468326921-26485-1-git-send-email-zajec5@gmail.com> (raw)
Hi,
I was working on an "usbport" LED trigger driver and specifying its
default state in DT. I realized I can't really determine numbering of
USB ports on any device as it depends on compiled drivers and the
loading orders.
It means that my physical USB port can be e.g. 1-1 or 2-1 depending on
my current config/setup. I needed a way to specify a particular HCD in
DT and then hardcode port number (as this part doesn't change).
These 2 patches add providers to usb core subsystem. I successfully
tested it with "usbport" trigger and generic-ohci, generic-ehci &
generic-xhci.
The last (third) patch is not supposed to be applied, it's used only as
a proof and example of how providers can be used.
If there is anything wrong with this idea/implementation, please let me
know.
