2013-03-18usb: dwc3: omap: introduce enable/disable IRQ methodsFelipe Balbi
they will be re-used on suspend/resume implementation. Tested-by: Vivek Gautam <gautam.vivek@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2013-03-18usb: dwc3: core: add power management supportFelipe Balbi
Add support for basic power management on the dwc3 driver. While there is still lots to improve for full PM support, this minimal patch will already make sure that we survive suspend-to-ram and suspend-to-disk without major issues.

2013-03-18usb: dwc3: gadget: save state of pullupsFelipe Balbi
This will be used during resume to verify if we should reconnect our pullups or not. Tested-by: Vivek Gautam <gautam.vivek@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2013-03-18usb: dwc3: gadget: introduce and use enable/disable irq methodsFelipe Balbi
we don't need to enable IRQs until we have a gadget driver loaded and ready to work, so let's delay IRQ enable to ->udc_start() and IRQ disable to ->udc_stop(). While at that, also move the related use of request_irq() and free_irq(). Tested-by: Vivek Gautam <gautam.vivek@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2013-03-18usb: dwc3: core: explicitly setup and cleanup event buffersFelipe Balbi
Make the call to dwc3_event_buffers_setup() and dwc3_event_buffers_cleanup() explicit, so it's easier to implement PM. Tested-by: Vivek Gautam <gautam.vivek@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

2013-03-18usb: gadget: udc-core: allow udc class register gadget deviceFelipe Balbi
Currently all UDC drivers are calling device_register() before calling usb_add_gadget_udc(). In order to avoid code duplication, we can allow udc-core.c register that device. However that would become a really large patch, so to cope with the meanwhile and allow us to write bite-sized patches, we're adding a flag which will be set by UDC driver once it removes the code for registering the gadget device. Once all are converted, the new flag will be removed. Reviewed-by: Tomasz Figa <tomasz.figa@gmail.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

2013-03-18usb: dwc3: omap: minor fixes to get dt workingKishon Vijay Abraham I
Includes few minor fixes in dwc3-omap like populating the compatible string in a correct way, extracting the utmi-mode property properly and changing the index of get_irq since irq of core is removed from hwmod entry. Also updated the documentation with dwc3-omap device tree binding information.

2013-03-18USB: phy: nop: Defer probe if device needs VCC/RESETRoger Quadros
Add 2 flags, needs_vcc and needs_reset to platform data. If the flag is set and the regulator couldn't be found then we bail out with -EPROBE_DEFER. For device tree boot we depend on presensce of vcc-supply/ reset-supply properties to decide if we should bail out with -EPROBE_DEFER or just continue in case the regulator can't be found. This is required for proper functionality in cases where the regulator is needed but is probed later than the PHY device.

2013-03-18usb: phy: nop: Handle RESET for the PHYRoger Quadros
We expect the RESET line to be modeled as a regulator with supply name "reset". The regulator should be modeled such that enabling the regulator brings the PHY device out of RESET and disabling the regulator holds the device in RESET. They PHY will be held in RESET in .shutdown() and brought out of RESET in .init(). Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
