[PATCH linux-next v2 0/1] usb: gadget: udc: atmel: Update endpoint allocation scheme

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Cristian Birsan <cristian.birsan@xxxxxxxxxxxxx>

Hi,

This patch updates the usb endpoint allocation scheme for atmel usba
driver to make sure all endpoints are allocated in order. This requirement
comes from the datasheet of the controller.

The allocation scheme is decided by fifo_mode parameter. For fifo_mode = 0
the driver tries to autoconfigure the endpoints fifo size. All other modes
contain fixed configurations optimized for different purposes. The idea is
somehow similar with the approach used on musb driver.

Please let me know if you have any comments or suggestions.

Changes since v1:
	- Minor reworks based on received fedback


Kind regards,
Cristian
