2015-03-18usb: chipidea: support runtime power management for otg fsm modeLi Jun1-0/+1
This patch adds runtime power management support for otg fsm mode, since A-device in a_idle state cannot detect data pulse irq after suspended, here enable wakeup by connection before suspend to make it can be resumed by DP; and handle wakeup from that state like SRP.

2015-03-18usb: chipidea: add chipidea revision informationPeter Chen1-0/+10
Define ci_get_revision API to know the controller revision information according to chipidea 1.1a, 2.0a and 2.5a spec. Besides, add one entry at struct ci_hdrc to indicate revision information, it can be used for adding different code for revisions, eg kinds of errata.

2014-04-24usb: chipidea: OTG fsm timers initializationLi Jun1-0/+1
This patch adds OTG fsm timers initialization, which use controller's 1ms interrupt as timeout counter, also adds some local timers which are not in otg_fsm_timer list.

2014-02-25usb: chipidea: udc: add maximum-speed = full-speed optionMichael Grzeschik1-0/+2
This patch makes it possible to set the chipidea udc into full-speed only mode. It is set by the oftree property "maximum-speed = full-speed".

2013-10-01usb: chipidea: add ci_hdrc_enter_lpm APIPeter Chen1-0/+1
This API is used to let the PHY enter/leave low power mode. Before the controller going to work(at probe/resume), it needs to let the PHY leave low power mode. After the controller stopping working(at remove/suspend), it needs to let the PHY enter low power mode to save power consumption.

2013-06-18usb: chipidea: add PTW, PTS and STS handlingMichael Grzeschik1-1/+15
This patch makes it possible to configure the PTW, PTS and STS bits inside the portsc register for host and device mode before the driver starts and the phy can be addressed as hardware implementation is designed.

2012-05-12usb: chipidea: add host roleAlexander Shishkin1-0/+1
This adds EHCI host support to the chipidea driver. We want it to be part of the hdrc driver and not a standalone (sub-)driver module, as the structure of ehci-hcd.c suggests, so for chipidea controller we hack it to not provide platform-related code, but only the ehci hcd. The ehci-platform driver won't work for us here too, because the controller uses the same registers for both device and host mode and also otg-related bits, so it's not really possible to put ehci registers into a separate resource. This is not a pretty solution, but the alternative is exporting symbols from the chipidea driver to a ehci-chipidea driver and doing all the module refcounting.

2012-05-12usb: chipidea: add support for rolesAlexander Shishkin1-0/+18
Add some generic code for roles and implement simple role switching based on ID pin state and/or a sysfs file. At this, we also rename the device to ci_hdrc, which is what it is. The "manual" switch is made into a sysfs file and not debugfs, because it might be useful even in non-debug context. For some boards, like sheevaplug, it seems to be the only way to switch roles without modifying the hardware, since the ID pin is always grounded.
