* usb: chipidea: using one inline function to cover queue work operationsPeter Chen2014-05-231-0/+5
| | | | | | | | | The otg queue work include operations: one is disable interrupt, another one is call kernel queue work API. Many codes do this operation, using one inline function to instead of them. Signed-off-by: Peter Chen <peter.chen@freescale.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* usb: chipidea: need to mask INT_STATUS when write otgscPeter Chen2014-01-131-3/+3
| | | | | | | | | | | | | | For otgsc, both enable bits and status bits are in it. So we need to make sure the status bits are not be cleared when write enable bits. It can fix one bug that we plug in/out Micro AB cable fast, and sometimes, the IDIS will be cleared wrongly when handle last ID interrupt (ID 0->1), so the current interrupt will not occur.

* usb: chipidea: add vbus interrupt handlerPeter Chen2013-08-141-0/+1
| | | | | | | | | | | | We add vbus interrupt handler at ci_otg_work, it uses OTGSC_BSV(at otgsc) to know it is connect or disconnet event. Meanwhile, we introduce two flags id_event and b_sess_valid_event to indicate it is an id interrupt or a vbus interrupt.

* usb: chipidea: otg: add otg file used to access otgscPeter Chen2013-08-141-0/+32
This file is mainly used to access otgsc currently, it may add otg related things in the future.
