[PATCH 00/11] usb: gadget: at91_udc: Rework for multi-platform support

[Boris Brezillon]

Hello,

This series reworks the at91_udc driver to prepare at91 for multi-platform
support.

It also include several fixes:
 - fix clock names to be consistent with other USB drivers
 - document clocks and clock-names properties in atmel-usb DT bindings doc

and some cleanup changes:
 - remove useless usb_clk
 - allocate at91_udc instance instead of using the statically defined one
 - simplify the probe and remove functions by using devm_ helpers
 - remove !DT specific code

The series depends on this patch [1] (which adds matrix registers definition).

Regards,

Boris
