extcon: max8997: Fix NULL pointer exception on missing pdata

2014-07-01T03:09:41+00:00

commit dfee4111febf3d9ef3a640b2cd6205c75f4e7e3d upstream.

Fix NULL pointer exception when platform data is not supplied. The
driver dereferenced pdata pointer where it could be NULL.

extcon: max8997: Fix return value

2013-04-08T22:53:46+00:00

Return the value obtained from the function instead of hardcoding.
Fixes the following warnings:
drivers/extcon/extcon-max8997.c:235 max8997_muic_set_path() info:
why not propagate 'ret' from max8997_update_reg() instead of (-11)?
drivers/extcon/extcon-max8997.c:248 max8997_muic_set_path() info:
why not propagate 'ret' from max8997_update_reg() instead of (-11)?

extcon: max8997: use dev_err() instead of pr_err()

2013-04-08T22:53:46+00:00

dev_err() is more preferred than pr_err().

extcon: max8997: Check the pointer of platform data to protect null pointer error

2013-03-13T08:28:15+00:00

This patch check the pointer of platform data to protect
kernel panic when platform data is not used and code clean.

extcon: max8997: Use workqueue to check cable state after completing boot of platform

2013-02-13T22:54:49+00:00

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 initialization

extcon: max8997: Set default UART/USB path on probe

2013-02-13T22:54:36+00:00

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).

extcon: max8997: Consolidate duplicate code for checking ADC/CHG cable type

2013-02-13T22:54:22+00:00

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'.

extcon: max8997: Set default of ADC debounce time during initialization

2013-02-13T22:54:09+00:00

This patch set default of ADC Debounce Time(25ms) during probe step.
Also, can possible change ADC Debounce Time according to H/W situation
by using max8997_set_adc_debounce_time()

2013-02-13T22:53:42+00:00

because of mask/unmask selectively interrupt of MUIC device according
to attribute of H/W board.
