From: Cristian Birsan <[email protected]>
This patch set adds usb device support for SAM9x60 SoC.
The DPRAM memory for the USB High Speed Device Port (UDPHS) hardware
block was increased and the allocation method is changed. This patch
series simplifies the endpoint allocation scheme to acomodate this SoC
and the old ones.
Changes in v2:
- drop the patch that adds reference to pmc for sam9x60
- use dt-bindings: usb prefix
- enable usb device in device tree
Claudiu Beznea (1):
usb: gadget: udc: atmel: use of_find_matching_node_and_match
Cristian Birsan (6):
dt-bindings: usb: atmel: Update DT bindings documentation for sam9x60

usb: gadget: udc: atmel: use 1 bank endpoints for control transfers

From: Claudiu Beznea <[email protected]>
Instead of trying to match every possible compatible use
of_find_matching_node_and_match() and pass the compatible array.

2.17.1
From: Cristian Birsan <[email protected]>
The DPRAM memory from the USB High Speed Device Port (UDPHS) hardware
block was increased. This patch updates the endpoint allocation for sam9x60
to take advantage of this larger memory. At the same time the
constraint to allocate the endpoints in order was lifted. To handle old
and new hardware in the same driver the capabilities (caps) structure
was extended.

This should probably be rebased on top of
https://lore.kernel.org/linux-arm-kernel/[email protected]/
so we avoid having to define the endpoints in the device tree in the
first place.

I know the patch series and I Ack-ed it some time ago. On the other hand, it was not applied yet,
so to be consistent I created this series based on what is already available on usb-next.
Depending on which one gets applied first, the other will need to rebase. I have no problem with that.
The end goal is to have both of them.
