mfd: max77693: Handle IRQs using regmap

2014-06-17T14:17:00+00:00

This patch modifies mfd driver to use regmap for handling interrupts.
It allows to simplify irq handling process. This modifications needed
to make small changes in function drivers, which use interrupts.

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: 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.

Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.
