2013-04-03usb: phy: ab8500-usb: fix last notifier argumentsFabio Baltieri1-7/+3
Fix last ab->phy.notifier call to use vbus_draw as notifier argument, as that's used in ab8500_charger to control charging current. Also drop a related TODO comment, and the additional ux500_musb_set_vbus(musb, 0), as with this patch it was causing an erratic behaviour of gadget ep0 state machine.

2013-03-27usb: gadget: mv_u3d: drop ARCH dependencyFelipe Balbi1-1/+1
this driver compiles fine everywhere which means we can use linux-next to compile it for us frequently. By dropping the arch dependency, we also ensure driver writers don't add virtual arch-depdencies to the driver by e.g. using the wrong headers. While at that, fix Marvell's USB3 PHY dependency, that's the driver which depends on CPU_MM3, not mv_u3d_core. Signed-off-by: Felipe Balbi <[email protected]>
2013-03-21usb: phy: twl4030-usb: poll for ID disconnectGrazvydas Ignotas1-7/+57
On pandora, STS_USB interrupt doesn't arrive on USB host cable disconnect for some reason while VBUS is driven by twl itself, but STS_HW_CONDITIONS is updated correctly. It does work fine when PHY is powered down though. To work around that we have to poll. This patch also moves twl->linkstat update code to callers so that changes can be handled in thread safe way (as polling work can trigger at the same time as real irq now). TI PSP kernels have similar workarounds, so (many?) more boards are likely affected. Signed-off-by: Grazvydas Ignotas <[email protected]> Signed-off-by: Felipe Balbi <[email protected]>
2013-03-21usb: phy: twl4030-usb: don't switch the phy on/off needlesslyGrazvydas Ignotas1-6/+0
With runtime_pm in place there is no longer need to turn the phy on/off in OTG layer on cable connect/disconnect, OMAP glue does this through otg.set_suspend() callback after it's called through omap_musb_mailbox() on VBUS/ID interrupt. Not doing this will save power when cable is connected but no gadget driver is loaded. This will also have side effect of automatic USB charging no longer working without twl4030_charger driver, because a regulator needed for charging will no longer be enabled, so be sure to enable charger driver if charging is needed.

2013-03-21usb: phy: twl4030-usb: ignore duplicate eventsGrazvydas Ignotas1-2/+3
In some rare cases we may get multiple interrupts that will generate duplicate omap_musb_mailbox() calls. This is a problem because each VBUS/ID event generates runtime_pm call in OMAP glue code, causing unbalanced gets or puts and breaking PM. The same goes for initial state, glue already defaults to "no cable" state, so only bother it if we have VBUS or ID.

2013-03-21usb: phy: twl4030-usb: don't enable PHY during initGrazvydas Ignotas1-11/+9
There is no need to do it, otg.set_suspend(false) (which itself comes from runtime_pm OMAP glue calls) will enable it later anyway. This used to be the place where things were enabled if booted with cable connected before runtime_pm conversion, but now can be dropped.
