usb: gadget: Gadget directory cleanup - group UDC drivers

2014-07-16T17:15:28+00:00

The drivers/usb/gadget directory contains many files. Files which are related can be distributed into separate directories. This patch moves the UDC drivers into a separate directory. Signed-off-by: Andrzej Pietrasiewicz Signed-off-by: Felipe Balbi

usb: delete non-required instances of include

2014-01-08T23:01:39+00:00

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. Signed-off-by: Paul Gortmaker Signed-off-by: Greg Kroah-Hartman

usb: gadget: add "maxpacket_limit" field to struct usb_ep

2013-12-17T19:17:41+00:00

This patch adds "maxpacket_limit" to struct usb_ep. This field contains maximum value of maxpacket supported by driver, and is set in driver probe. This value should be used by autoconfig() function, because value of field "maxpacket" is set to value from endpoint descriptor when endpoint becomes enabled. So when autoconfig() function will be called again for this endpoint, "maxpacket" value will contain wMaxPacketSize from descriptior instead of maximum packet size for this endpoint. For this reason this patch adds new field "maxpacket_limit" which contains value of maximum packet size (which defines maximum endpoint capabilities). This value is used in ep_matches() function used by autoconfig(). Value of "maxpacket_limit" should be set in UDC driver probe function, using usb_ep_set_maxpacket_limit() function, defined in gadget.h. This function set choosen value to both "maxpacket_limit" and "maxpacket" fields. This patch modifies UDC drivers by adding support for maxpacket_limit.

usb: gadget: amd5536udc: unconditionally use GFP_ATOMIC in udc_queue()

2013-08-09T13:33:31+00:00

As far as prep_dma() is called with spinlock held, we have to pass GFP_ATOMIC regardless of gfp argument. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by: Alexey Khoroshilov Signed-off-by: Felipe Balbi

usb: gadget: amd5536udc: don't assign gadget.dev.release directly

udc-core provides a better way to handle release methods, let's use it. Signed-off-by: Felipe Balbi

usb: gadget: amd5536udc: don't touch gadget.dev.driver

2013-03-18T09:17:32+00:00

udc-core handles that for us, which means we can remove it from our driver. Signed-off-by: Felipe Balbi

usb: gadget: amd5536udc: remove unnecessary initializations

udc-core now sets dma-related and parent fields for us, we don't need to do it ourselves. Signed-off-by: Felipe Balbi

usb: gadget: drop now unnecessary flag

2013-03-18T09:16:55+00:00

We don't need the ->register_my_device flag anymore because all UDC drivers have been properly converted. Let's remove every history of it. Signed-off-by: Felipe Balbi
