2013-09-27extcon: Simplify extcon_dev_register() prototype by removing unnecessary ↵Chanwoo Choi1-1/+2
parameter This patch remove extcon_dev_register()'s second parameter which means the pointer of parent device to simplify prototype of this function. So, if extcon device has the parent device, it should set the pointer of parent device to edev.dev.parent in extcon device driver instead of in extcon_dev_register().

2013-09-27extcon: use dev_get_platdata()Jingoo Han1-1/+1
Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. This is a cosmetic change to make the code simpler and enhance the readability. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>
2013-08-05extcon: palmas: Option to disable ID/VBUS detection based on platformLaxman Dewangan1-35/+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.

2013-08-05extcon: palmas: enable ID_GND and ID_FLOAT detection alwaysLaxman Dewangan1-13/+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.

2013-08-05extcon: palmas: remove assigning "edev.name" to palmasKishon Vijay Abraham I1-1/+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.
