* extcon: palmas: Option to disable ID/VBUS detection based on platformLaxman Dewangan2013-08-051-35/+52
| | | | | | | | | | | Based on system design, platform needs to detect the VBUS or ID or both. Provide option to select this through platform data to disable part of cable detection through palmas-usb.

* extcon: palmas: enable ID_GND and ID_FLOAT detection alwaysLaxman Dewangan2013-08-051-13/+11
| | | | | | | | | | | | | | | | | | | | | When integrating driver with Tegra platform, it is found that the ID pins get detected only once after booting system and further removal and re-insert does not detect the ID pin. Fixing this issue with enabling interrupt on ID_GND and ID_FLOAT always and clearing the status on LATCH register which actually occurred. Also if interrupt occurs with line status as zero then based on previous status, set the cable state. Add debug prints to display the cable state when any cable insertion/removal happen.

* extcon: palmas: remove assigning "edev.name" to palmasKishon Vijay Abraham I2013-08-051-1/+0
| | | | | | | | | | | | | | of_extcon_get_extcon_dev() uses dev_name for getting the reference to the extcon device. If the extcon driver assigns a different name other than dev_name, of_extcon_get_extcon_dev() wouldn't be able to find the reference to the extcon device. Since the client drivers of extcon-palmas would be using of_extcon_get_extcon_dev(), removed assigning edev.name in extcon-palmas.

This is the driver for the USB comparator built into the palmas chip. It handles the various USB OTG events that can be generated by cable insertion/removal.
