usb: chipidea: need to mask INT_STATUS when write otgsc 2014-01-13T23:55:19+00:00 Peter Chen peter.chen@freescale.com 2014-01-10T05:51:31+00:00 5332ff1fb63c46588656e4208201bc131627c878 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 handler 2013-08-14T19:37:20+00:00 Peter Chen peter.chen@freescale.com 2013-08-14T09:44:11+00:00 a107f8c505cd8606ae192d24c70b380e980fbe67 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.
