* usb: otg: Temporarily grab wakelock on charger and disconnect eventsTodd Poynor2011-09-261-77/+56

* usb: otg_id: add suspend/resume interfaceDima Zavin2011-09-111-0/+59
| | | | | | | | | | | | | | | | | | It is possible that while one driver has already suspended, another driver calls otg_id_notify() because it has not yet been suspended. It would then be possible for the suspended driver's detect callback to be called. This is undesirable. Introduce new otg_id_suspend/otg_id_resume functions that keep a suspended count, and if a notification happens while someone is suspended, that notification is deferred until all the drivers are resumed. If the notification happens before the last driver is suspended, that suspend will be aborted and once the final driver resumes through otg_id_resume, the notification will be delivered.

| | | | | | | | Some otg_id handlers can detect what's connected but can't detect a change. This allows that handler to pass off the waiting for ID change to a proxy. Change-Id: Ib38b750c3da4bffc35e37b620ecee37c5d64d31f Signed-off-by: Erik Gilling <konkers@android.com>

* USB: TWL6025 allow different regulator nameGraeme Gregory2011-05-271-1/+9
| | | | | | | | | | | | | The twl6025 uses a different regulator for USB than the 6030 so select the correct regulator name depending on the subclass of device. Since V1 Use features passed via platform data instead of global variable.

* USB: OTG: msm: Free VCCCX regulator even if we can't set the voltageMark Brown2011-05-171-3/+1
| | | | | | | | | | If for some reason we fail to set the voltage range for the VDDCX regulator when removing it's better to still disable and free the regulator as that avoids leaking a reference to it and is likely to ensure that it's turned off completely.

* USB: OTG: msm: Allow the widest possible range for VDDCX when removingMark Brown2011-05-171-1/+1
| | | | | | | | | | | When not active the hardware should be able to tolerate voltages within the normal operating range so when removing set the maximum voltage we can use to the maximum rather than minimum of the operating range. This will improve interoperability in case we end up sharing the supply in some design.

* USB: OTG: msm: Implement charger detectionPavankumar Kondeti2011-05-061-4/+376
| | | | | | | | | | | | | | | | | Implement good battery algorithm defined in the battery charging V1.2 spec for detecting different charging ports. USB hardware is put into low power mode when connected to a dedicated charging port. vbus_draw and set_power methods are implemented for determining the allowed current from Host in different states (un-configured/suspend/configured). The charger block is implemented using vendor specific registers and the PHY used in MSM8960(28nm PHY) different from older targets like MSM8x60 and MSM7x30(45nm PHY). The PHY vendor and product id registers are not implemented in the above chipsets. Hence PHY type is passed via platform data.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding the twl6030-usb transceiver support for OMAP4 musb driver. OMAP4 supports 2 types of transceiver interface. 1. UTMI: The PHY is embedded within OMAP4. The transceiver functionality is split between the twl6030 PMIC chip and OMAP4430. The VBUS, ID pin sensing and OTG SRP generation part is integrated in TWL6030 and UTMI PHY functionality is embedded within the OMAP4430. There is no direct interactions between the MUSB controller and TWL6030 chip to communicate the session-valid, session-end and ID-GND events. It has to be done through a software by setting/resetting bits in one of the control module register of OMAP4430 which in turn toggles the appropriate signals to MUSB controller. The internal transceiver has functional clocks and powerdown bits to powerdown the PHY for power saving. Since there is no option available for having 2 transceiver drivers for one USB controller, internal PHY specific APIs are passed through plaform_data function pointers to use in the twl6030-usb transceiver driver. 2. ULPI interface is provided for off-chip transceivers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement runtime and system pm ops to put hardware into low power mode (LPM). As part of LPM, USB clocks are turned off, PHY is put into suspend state and PHY comparators are turned off if VBUS/Id notifications are not required from PHY.

| |/ | | | | | | | | | | | | | | | | | | This driver implements PHY initialization, clock management, ULPI IO ops and simple OTG state machine to kick host/peripheral based on Id/VBUS line status. VBUS/Id lines are tied to a reference voltage on some boards. Hence provide debugfs interface to select host/peripheral mode.

| * usb: otg: twl4030-usb: Fix unbalanced regulator disables at module removalJarkko Nikula2010-11-301-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Function twl4030_usb_remove can cause unbalanced regulator disables in twl4030_phy_power if the cable is not connected. Regulator enable/disable calls are in balance only if the twl4030_phy_resume was called prior the twl4030_usb_remove, that is, the cable was connected. Fix this by checking the 'asleep' variable in twl4030_usb_remove since that variable is used to check state in other functions.
