2011-08-19wm831x_power: Only register WM831x battery charger if enabledMark Brown2-18/+30
Don't tell the system about the battery charger if it's not enabled, we can reasonably assume that if the charger is not enabled then no battery will ever be connected so reporting state is at best going to waste time and at worst going to cause confusing information in the UI. For simplicity and robustness we continue to register and handle interrupts from the charger.

2011-08-19pda_power: Add support for using otg transceiver eventsDima Zavin1-12/+59
If the platform data sets the use_otg_notifier flag, the driver will now register an otg notifier callback and listen to transceiver events for AC/USB plug-in events instead. This would normally be used by not specifying is_xx_online callbacks and not specifying any irqs so the state machine is completely driven from OTG xceiver events.

Since then the test_power driver has been merged, which provides very similar functionality. This patch extends the test_power driver to be more dynamic at runtime, by merging portions of the Virtual Battery Driver by Masashi YOKOTA. With this patch, I can tweak the values in: /sys/module/test_power/parameters/* and watch the behavior of the gnome power managment daemon or other battery UI software.

2011-03-16bq20z75: Fix issues with present and suspendRhyland Klein1-11/+21
There are a few issues found around the battery not being present. If the battery isn't present, then a few undesirable things happen. The first was excessive reporting of failed properties. This was fixed by instead returning ENODATA for all properties other than PRESENT if the battery isn't present. That way the callers can identify the difference between a failure and the battery not being there. The next issue was in the suspend logic. It was found that if the battery wasn't present, then it would return a failure, preventing the system from going into suspend. If there is no battery present, the io is expected to fail, so in that case, we shouldn't return the failure and just acknowledge that it was expected. I also found that when a gpio was used, i didn't maintain the internal is_present state properly. I added a set of that to fix that. Lastly, the code to see io's fail and figure out that the battery isn't present when not using a gpio had a problem. In that code, it looked for the read to fail and if it did, then handled it. The problem is that in function to get the property, it first writes a value and that write can fail, causing the code to never reach the logic after the read. Fix is to move the logic till after the write. Signed-off-by: Rhyland Klein <rklein@nvidia.com> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>
