extcon: max77693: Initialize register of MUIC device to bring up it without platform data

2013-03-13T08:38:57+00:00

This patch set default value of MUIC register to bring up MUIC device.

If user don't set some initial value for MUIC device through platform data,
extcon-max77693 driver use 'default_init_data' to bring up base operation
of MAX77693 MUIC device.

extcon: max77693: Fix bug of wrong pointer when platform data is not used

2013-03-13T08:32:35+00:00

This patch fix wrong pointer of platform data. If each machine set
platform data for h/w path or delay time of workqueue, this driver
happen kernel panic related to null pointer.

extcon: max77693: Add support Dock-Smart device for desktop mode

2013-01-15T06:42:16+00:00

This patch support the detection of Dock-Smart device which include
three type of port(HDMI, USB for mouse/keyboard and Micro-USB for
USB/TA cable).The Dock-Smart device need always exteranl power supply
(USB/TA cable through micro-usb cable). Dock-Smart device support screen
output of target to separate monitor and mouse/keyboard for desktop
mode.

Features of 'Dock-Smart device'
- Support HDMI
- Support external output feature of audio
- Support charging through micro-usb port without data
  connection if TA cable is connected to target.
- Support charging and data connection through micro-usb port
  if USB cable is connected between target and host device.
- Support OTG device (Mouse/Keyboard)

extcon: max77693: Fix bug when detecting MHL/Dock-Audio with USB/TA cable

2013-01-15T06:42:16+00:00

This patch fix bug that muic couldn't detect MHL/Dock-Audio with USB/TA
cable on exception situation. I explain detail case on following:

When MHL(with USB/TA cable) or Dock-Audio with USB/TA cable is attached,
the MUIC device happen following two interrupt.
- 'MAX77693_MUIC_IRQ_INT1_ADC' for detecting MHL/Dock-Audio.
- 'MAX77693_MUIC_IRQ_INT2_CHGTYP' for detecting USB/TA cable connected to
MHL/Dock-Audio. Always, happen eariler MAX77693_MUIC_IRQ_INT1_ADC interrupt
than MAX77693_MUIC_IRQ_INT2_CHGTYP interrupt.

If user attach MHL with USB/TA cable and immediately detach MHL with USB/TA
cable before MAX77693_MUIC_IRQ_INT2_CHGTYP interrupt is happened, USB/TA
connected to MHL cable remain connected state to target. But USB/TA connected
to MHL cable isn't connected to target. user be faced with unusual action.
So, driver should check this situation in spite of that, previous charger type
is N/A.

extcon: max77693: Set default uart/usb path by using platform data

2013-01-15T06:42:16+00:00

This patch determine default uart/usb path by using platform data.
The MAX77693 MUIC device can possibliy set USB/UART/AUDIO/USB_AUX
/UART_AUX to internal h/w path of MUIC device. So, drvier should
determine default uart/usb path.

extcon: max77693: Check the state/type of cable after boot completed

2013-01-15T06:42:15+00:00

This patch check the state/type of cable after completing the initialization
of platform and notify platform of cable state/type through extcon. If extcon
provider driver notify the state/type of cable before completing platform boot,
this uevent is unused and ignored.
