mfd: max77693: Modify flash cell name identifiers

2015-03-12T09:07:54+00:00

Change flash cell identifiers from max77693-flash to max77693-led
to avoid confusion with NOR/NAND Flash.

mfd: max77693: Map charger device to its own of_node

2014-11-25T16:18:46+00:00

Add a "maxim,max77693-charger" of_compatible to the mfd_cell so the MFD
child device (the charger) will have its own of_node set. This will be
used by the max77693 charger driver in next patches to obtain battery
configuration from DTS.

mfd: max77693: Fix always masked MUIC interrupts

2014-11-10T15:22:02+00:00

All interrupts coming from MUIC were ignored because interrupt source
register was masked.

The Maxim 77693 has a "interrupt source" - a separate register and interrupts
which give information about PMIC block triggering the individual
interrupt (charger, topsys, MUIC, flash LED).

By default bootloader could initialize this register to "mask all"
value. In such case (observed on Trats2 board) MUIC interrupts won't be
generated regardless of their mask status. Regmap irq chip was unmasking
individual MUIC interrupts but the source was masked

Before introducing regmap irq chip this interrupt source was unmasked,
read and acked. Reading and acking is not necessary but unmasking is.

mfd: max77693: Use proper regmap for handling MUIC interrupts

2014-11-10T15:22:01+00:00

Interrupts coming from Maxim77693 MUIC block (MicroUSB Interface
Controller) were not handled at all because wrong regmap was used for
MUIC's regmap_irq_chip.

The MUIC component of Maxim 77693 uses different I2C address thus second
regmap is created and used by max77693 extcon driver. The registers for
MUIC interrupts are also in that block and should be handled by that
second regmap.

However the regmap irq chip for MUIC was configured with default regmap
which could not read MUIC registers.

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.
