mfd: max77693: Make of_device_id array const

2014-06-03T07:11:32+00:00

Array of struct of_device_id may be be const as expected by

mfd: max77693: Fix possible NULL pointer dereference on i2c_new_dummy error

2014-03-19T08:58:12+00:00

During probe the driver allocates dummy I2C devices for MUIC and haptic
with i2c_new_dummy() but it does not check the return value of this
calls.

In case of error (i2c_new_device(): memory allocation failure or I2C
address cannot be used) this function returns NULL which is later used
by devm_regmap_init_i2c() and i2c_unregister_device().

If i2c_new_dummy() fails for MUIC or haptic devices, fail also the probe
for main MFD driver.

mfd: max77693: Set proper maximum register for MUIC regmap

2014-01-21T08:28:13+00:00

The MUIC block in max77693 has different I2C address than PMIC. The
driver allocated two regmaps: for PMIC and MUIC. However it used the
same regmap_config (with max_register field) for both regmaps. Actual
maximum address of register for MUIC is different than for PMIC.

Define another regmap_config for MUIC with proper max_register value.

mfd: maxim: Constify struct mfd_cell where possible

2014-01-06T09:13:27+00:00

As of commit 03e361b25ee8dfb1fd9b890072c23c4aae01c6c7 ("mfd: Stop setting
refcounting pointers in original mfd_cell arrays"), the "cell" parameter of
mfd_add_devices() is "const" again. Hence make all cell data passed to
mfd_add_devices() const where possible.

mfd: max77693: Include linux/of.h header

'of_match_ptr' is defined in linux/of.h. Include it explicitly to
avoid build breakage in the future.

mfd: max77693: Remove device wakeup from driver

2013-10-23T15:21:26+00:00

The patch removes wakeup related code from the driver and plaftorm
data - it is already handled by i2c core using I2C_CLIENT_WAKE flag
from struct i2c_board_info. As a result MFD itself do not requires
platform data.

mfd: max77693: Init max77693->dev before using it

2013-01-22T02:02:22+00:00

Current code uses max77693->dev in the dev_err call before setting it to
&i2c->dev. Fix it.

This patch also includes below cleanups:
 - Move checking pdata earlier and show dev_err if no platform data found.
 - Remove unnecessary err_regmap goto label.
 - Unregister i2c devices if regmap init for muic fails.

Maxim MAX77693 is initialized before call max77693-muic probe() function.
