d860852e08 USB: OTG: msm: Implement charger detection
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.

0f73cac8e4 USB: OTG: msm: vote for dayatona fabric clock
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

2ce2c3ac88 USB: OTG: msm: Clear in_lpm flag before enabling the IRQ in resume
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.

dfb2130c45 USB: Rename "msm72k_otg.c" to "msm_otg.c"
This driver is used across all MSM SoCs.  Hence give a generic name.
All Functions and strutures are also using "msm_otg" as prefix.
