* twl4030_charger: Add devicetree supportNeilBrown2013-11-121-3/+44
| | | | | | | | | | This allows the charger to be enabled with devicetree, and allows the parameters for charging the backup battery to be set.

* twl4030-charger: Fix compiler warning with regulator_enable()Peter Ujfalusi2013-08-271-1/+6
| | | | | | | | | | The return value of regulator_enable need to be checked. This patch fixes the following warning: drivers/power/twl4030_charger.c: In function ‘twl4030_charger_enable_usb’: drivers/power/twl4030_charger.c:192:20: warning: ignoring return value of ‘regulator_enable’, declared with attribute warn_unused_result [-Wunused-result] Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Anton Vorontsov <anton@enomsg.org>
* twl4030_charger: Remove unnecessary platform_set_drvdata()Jingoo Han2013-06-061-2/+0
| | | | | | | | | | The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is not needed to manually clear the device driver data to NULL. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Anton Vorontsov <anton@enomsg.org>
* twl4030_charger: Use module_platform_driver_probe()Jingoo Han2013-03-311-11/+1

* Merge tag 'for-v3.6' of git://git.infradead.org/battery-2.6Linus Torvalds2012-07-311-3/+77
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pull battery updates from Anton Vorontsov: "The tag contains just a few battery-related changes for v3.6. It's is all pretty straightforward, except one thing. One of our patches added thermal support for power supply class, but thermal/ subsystem changed under our feet. We (well, Stephen, that is) caught the issue and it was decided[1] that I'd just delay the battery pull request, and then will fix it up by merging upstream back into battery tree at the specific commit. That's not all though: another[2] small fixup for thermal subsystem was needed to get rid of a warning in power supply subsystem (the warning was not drivers/power's "fault", the thermal registration function just needed a proper const annotation, which is also done by a small commit on top of the merge. So, to sum this up: - The 'master' branch of the battery tree was in the -next tree for weeks, was never rebased, altered etc. It should be all OK; - Although, for-v3.6 tag contains the 'master' branch + merge + the warning fix.

| * twl4030_charger: Allow charger to control the regulator that feeds itNeilBrown2012-06-191-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | The charger needs usb3v1 to be running, so add a new consumer to keep it running. This allows the charger to draw current even when the USB driver has powered down.

| * twl4030_charger: Add backup-battery chargingNeilBrown2012-06-191-0/+59
| | | | | | | | | | | | | | | | | | | | | | | | This allows a voltage and current (bb_uvolts and bb_uamps) to be specified in the platform_data, and charging of the backup battery will be enabled with those specification. As it is not possible to monitor the backup battery at all there is no new device created to represent it.

| | | | | | | | | | | | | | | | | | usb_get_phy will return -ENODEV if it's not able to find the phy.

| | | | | | | | | | | | | | | | | | | | | | Add a linked list for keeping multiple PHY instances with different types so that we can have separate USB2 and USB3 PHYs on one single board. _get_phy_ has been changed so that the controller gets the transceiver by type. _remove_phy_ has been added to let the phy be removed from the phy list.
