2010-03-02usb: otg: twl4030: move to request_threaded_irqFelipe Balbi
move to request_threaded_irq() on twl4030 children. Signed-off-by: Felipe Balbi <felipe.balbi@nokia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-03-02USB: otg: twl4030: add support for notifierFelipe Balbi
it's expected that the transceiver driver will initialize and call the notifier chain when necessary. Implement that for twl4030-usb driver. Signed-off-by: Felipe Balbi <felipe.balbi@nokia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-13mfd: Rename all twl4030_i2c*Balaji T K
This patch renames function names like twl4030_i2c_write_u8, twl4030_i2c_read_u8 to twl_i2c_write_u8, twl_i2c_read_u8 and also common variable in twl-core.c Signed-off-by: Rajendra Nayak <rnayak@ti.com> Signed-off-by: Balaji T K <balajitk@ti.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Acked-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2009-12-13mfd: Rename twl4030* driver files to enable re-useSantosh Shilimkar
The upcoming TWL6030 is companion chip for OMAP4 like the current TWL4030 for OMAP3. The common modules like RTC, Regulator creates opportunity to re-use the most of the code from twl4030. This patch renames few common drivers twl4030* files to twl* to enable the code re-use.

2009-12-11USB: twl4030: Enable USB regulators before enabling USB chargingAguilar Pena, Leed
For TWL family of power management ICs, USB charging works only when USB regulators are in enabled state: 3v1, 1v5, 1v8 On a USB cable attach, twl4030_phy_resume(twl) function enables the regulators. Enable USB charging, only after all regulators are enabled. Its observed that enabling USB charging before regulators are enabled, causes USB charging to fail. Tested on: Zoom2: omap3430: ES3.1 + TWL5030 Needs T2-MADC and T2-BCI drivers which are still not upstreamed.

2009-06-15USB: twl4030-usb: fix minor reporting goofageDavid Brownell
Fix a reporting glitch in the twl4030 USB transceiver code. It wasn't properly distinguishing the two types of active USB link: ID grounded, vs not. In the current code that distinction doesn't much matter; in the future this bugfix should help support better USB controller communications. Provide a comment sorting out some of the cryptic bits of the manual: different sections use different names for key signals, and the register definitions don't help much without the explanations and diagrams.

2009-06-15USB: move twl4030_usb's probe function to .devinit.textUwe Kleine-König
A pointer to twl4030_usb_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

2009-03-24USB: TWL: disable VUSB regulators when cable unpluggedJouni Hogander
This patch disables USB regulators VUSB1V5, VUSB1V8, and VUSB3V1 when the USB cable is unplugged to reduce power consumption. Added a depencency from twl4030 usb driver to TWL_REGULATOR.

2009-01-07USB: otg: twl4030 transceiver driverDavid Brownell
Add driver for the high speed USB-OTG transceiver in TI's TWL4030 family of chips. Given this and various other pending patches, OMAP3 hardware like that from beagleboard.org, gumstix.com (Overo), and openpandora.org should now have basic USB host and peripheral connectivity with mainline kernels. Ditto for less widely-available boards.
