2012-08-13power: smb349: correct charger statusAllen Yu
When tegra-otg suspends with charger cable connected, the charger state and type should not be changed, neither should the charger callback be executed. SMB349 has a debounce delay of ~20ms +/- 3 after cable is unpluged and will stop all I2C functions for 2.3ms when getting reset to POR. Add 50ms' delay before reading charger status to avoid I2C error and make sure we get the right charger state.

2012-06-13power: smb349: fix I2C error when unplug ext powerSyed Rafiuddin
When unplug the external power, SMB349 will reload the OTP setting. It sometimes caused I2c errors. See bug 996103 and 991401. Add a 50ms delay when hotplugging the external power to fix the issue. SMB349 might mistakenly detect dedicated USB charger as standard USB device if plug in the USB at low speed. See Bug 996108. Add a 500ms delay to fix the issue.

2012-05-21power: smb349: support for self-powered devicesChandler Zhang
Some self-powered devices doesn't strictly follow USB spec that has 5V Vbus to upstream cannot work with mux on the data lines. The MAX4983 mux routes the data lines to SMB349 rather than the Tegra chip when PGOOD polarity is low-active and DCIN is 5V. Change PGOOD not to invert polarity for the devices that has 5V to upstream.
