This patch fix compilation error when driver is compiled
in multi-platform builds.
drivers/built-in.o: In function `msm_otg_link_clk_reset':
./drivers/usb/phy/phy-msm-usb.c:314: undefined reference to `clk_reset'
./drivers/usb/phy/phy-msm-usb.c:318: undefined reference to `clk_reset'
Use platform data supplied reset handlers and adjust error
messages reported when reset sequence fail.
This is an intermediate step before adding support for reset
framework and newer targets.

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

This driver is used across all MSM SoCs. Hence give a generic name.
All Functions and strutures are also using "msm_otg" as prefix.

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.
