usb: dwc3: fix the glue drivers using the nop phy

2013-12-19T15:27:41+00:00

The reset_gpio member of the usb_phy_gen_xceiv_platform_data
structure needs the have negative value or phy-generic's
probe will fail unless DT is used. 0 is a valid gpio number.

This fixes an issue where phy-generic fails to probe with
message: "usb_phy_gen_xceiv.0: Error requesting RESET GPIO 0".

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: dwc3: omap: remove unnecessary lock

2013-12-09T16:01:40+00:00

the lock was only taken inside the hardirq
handler, which runs with IRQs disabled. There's
no chance of any race condition happening, even
on SMP machines. It's safe to remove that
spinlock.

usb: dwc3: dwc3-omap: return PROBE_DEFER if extcon is missing and found in dt

2013-11-26T16:35:15+00:00

Due to inter dependencies of I2C and extcon by the time dwc3
checks for extcon device its not registered especially in case of J6.
In O5 the vbus regulator save us from getting to this point.
So for tiime being return PROBE_DEFER if extcon is enabled in dt.
