From: Cristian Birsan <cristian.birsan@microchip.com> 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 Cristian Birsan (1): usb: gadget: udc: atmel: Update endpoint allocation scheme drivers/usb/gadget/udc/Kconfig | 14 ++ drivers/usb/gadget/udc/atmel_usba_udc.c | 236 +++++++++++++++++++++++++++----- drivers/usb/gadget/udc/atmel_usba_udc.h | 10 +- 3 files changed, 227 insertions(+), 33 deletions(-) -- 2.7.4
