usb: chipidea: otg: add a_alt_hnp_support response for B device

2015-04-17T00:11:40+00:00

[ Upstream commit d20f7807996c69537e07443ef8dec4e01a28b099 ]

This patch adds response to a_alt_hnp_support set feature request from legacy
A device, that is, B-device can provide a message to the user indicating that
the user needs to connect the B-device to an alternate port on the A-device.
A device sets this feature indicates to the B-device that it is connected
to an A-device port that is not capable of HNP, but that the A-device does have
an alternate port that is capable of HNP.

[Peter]
Without this patch, the OTG B device can't be enumerated on
non-HNP port at A device, see below log:

usb: chipidea: Fix oops when removing the ci_hdrc module

2014-10-27T02:01:05+00:00

The call of 'kfree(ci->hw_bank.regmap)' in ci_hdrc_remove() sometimes causes
a kernel oops when removing the ci_hdrc module.

Since there is no separate memory allocated for the ci->hw_bank.regmap array,
there is no need to free it.

usb: rename phy to usb_phy in HCD

2014-09-29T15:52:59+00:00

The USB PHY member of the HCD structure is renamed to 'usb_phy' and
modifications are done in all drivers accessing it.
This is in preparation to adding the generic PHY support.

usb: gadget: Refactor request completion

2014-09-25T14:58:50+00:00

Use the recently introduced usb_gadget_giveback_request() in favor of
direct invocation of the completion routine.

All places in drivers/usb/ matching "[-.]complete(" were replaced with a
call to usb_gadget_giveback_request(). This was compile-tested with all
ARM drivers enabled and runtime-tested for musb.

usb: chipidea: otg initialization is only needed when the gadget is supported

2014-09-24T04:32:31+00:00

We have only needed to enable otg initialization when both of
below conditions are satisfied:

- The controller is otg capable
- The gadget function is enabled

If the controller is otg capable, but is host-only configuration, we do
not need to access register otgsc and do any otg operations (eg, create
otg workqueue).

chipidea: usbmisc_imx: Add USB support for VF610 SoCs

2014-09-24T04:32:30+00:00

This adds Vybrid VF610 SoC support. The IP is very similar to i.MX6,
however, the non-core registers are spread in two different register
areas. Hence we support multiple instances of the USB misc driver
and add the driver instance to the imx_usbmisc_data structure.

usb: chipidea: add TPL support for targeted hosts

2014-09-24T04:28:41+00:00

For OTG and Embedded hosts, they may need TPL (Targeted Peripheral List)
for usb certification and other vender specific requirements, the
platform can tell chipidea core driver if it supports tpl through DT
or platform data.

PHY drivers keep track of the current state of the hardware,
so don't change PHY settings under it.
