This patch use delayed workqueue to check cable state after a certain
time. If extcon-max8997 driver check cable state during booting of
platform, this couldn't send the correct notification of cable state
to extcon consumer. Alwasys, this driver should check cable state
after the completion of platform initializationSigned-off-by: Chanwoo Choi

This patch set default H/W line path according to platfomr data.
The MAX8997 MUIC device can possibly set UART/USB or UART_AUX
/USB_AUX to internal H/W line path of MUIC device. Namely, only
one H/W line is used for two operation.For example,
if H/W line path of MAX8997 device set UART/USB, micro usb cable
is connected to AP(Application Processor) and if H/W line path
set UART_AUX/USB_AUX, micro usb cable is connected to CP(Coprocessor).Signed-off-by: Chanwoo Choi

This patch make max8997_muic_get_cable_type() function to remove
duplicate code for checking ADC/Charger cable type because almost
internal function need to read adc/chg_type value of MUIC register.Also, remove *_detach() function, extcon-max8997 driver treat
attach/detach operation of cable in max8997_*_handler() function.
Lastly, this patch move defined constant in header file(include/
linux/mfd/max8997.h, max8997-private.h) because defined constant
is only used in the 'extcon-max8997.c'.Signed-off-by: Chanwoo Choi

With some GPIO control it is possible to detect microphones in a wider
range of configurations by directly measuring the microphone impedance
when the HPDET method cannot distinguish between the behaviour of the
two grounds. Allow a GPIO to be provided in platform data and use it to
implement this behaviour.Signed-off-by: Mark Brown

The accessory detection functionality in Arizona devices is flexible and
supports several system designs in addition to the default one implemented
by the existing driver. One such design uses the HPDET feature to determine
what kind of accessory is present by comparing measurements taken with the
two headphone grounds available on the device, implement that if selected
by platform data.Signed-off-by: Mark Brown

(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.

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.Signed-off-by: Chanwoo Choi
