USB: TWL6025 allow different regulator name

2011-05-27T09:49:30+00:00

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 voltage

2011-05-17T18:20:23+00:00

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 removing

2011-05-17T18:20:23+00:00

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: TWL6030: OMAP4430: Adding SRP VBUS pulsing API

2011-05-13T11:43:55+00:00

Implement the start_srp API to generate the VBUS pulsing and assign it to
otg_transciever function pointer. This will be used by the link driver when
there is SRP initiation from user.

USB: OTG: msm: Implement charger detection

2011-05-07T01:27:48+00:00

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.

USB: OTG: msm: vote for dayatona fabric clock

2011-05-07T01:27:48+00:00

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

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

2011-05-03T17:25:26+00:00

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.

USB: gpio-vbus: ask for vbus_draw regulator before registering xceiv

Ask for vbus_draw regulator before registering tranceiver to disallow possible
race between registration and set_power/etc.
