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.

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.

HSUSB core clock is derived from daytona fabric clock and for HSUSB operational require minimum core clock at 55MHz. Since, HSUSB cannot tolerate daytona fabric clock change in the middle of HSUSB operational, vote for maximum Daytona fabric clock while usb is operational Signed-off-by: NAnji jonnala <anjir@codeaurora.org> Signed-off-by: NPavankumar Kondeti <pkondeti@codeaurora.org> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

The current code is clearing in_lpm flag after enabling the IRQ. If IRQ comes immediately before in_lpm flag is set, it thinks that hardware is in low power mode and disables the IRQ. Fix this by clearing in_lpm flag before enabling the IRQ. Signed-off-by: NPavankumar Kondeti <pkondeti@codeaurora.org> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

This driver is used across all MSM SoCs. Hence give a generic name. All Functions and strutures are also using "msm_otg" as prefix. Signed-off-by: NPavankumar Kondeti <pkondeti@codeaurora.org> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

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.
