mfd: max14577: Don't pass IRQ domain to mfd_add_devices

2014-09-26T07:23:54+00:00

The max14577 MFD cells do not have any resources so the IRQ domain
passed to mfd_add_devices is not used.

regulator/mfd: max14577: Export symbols for calculating charger current

2014-09-24T14:25:47+00:00

This patch prepares for changing the max14577 charger driver to allow
configuring battery-dependent settings from DTS.

The patch moves from regulator driver to MFD core driver and exports:
 - function for calculating register value for charger's current;
 - table of limits for chargers (MAX14577, MAX77836).

Previously they were used only by the max14577 regulator driver. In next
patch the charger driver will use them as well. Exporting them will
reduce unnecessary code duplication.

mfd: max14577: Map charger device to its own of_node

2014-09-24T12:42:46+00:00

Add a "maxim,max14577-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 max14577 charger driver in next patches to obtain battery
configuration from DTS.

mfd: max14577: Make mfd_cell array const

Array of struct of_device_id should be const as expected by both
of_match_table field and of_match_device() call.

mfd: max14577: Fix IRQ handling after resume if this is not a wakeup source

2014-06-03T07:11:23+00:00

During suspend the IRQ should be disabled even if this is not a wakeup
source. This is a proper way of fixing the IRQ handling issue during
resume (IRQ handler fails because I2C bus did not resume yet).

When device is suspended and max14577 interrupt is signaled the irq chip
will try to handle it regardless of wakeup source. Device could be woken
up by different IRQ but still the IRQ handler will try to read the
registers over I2C bus and fail because I2C bus won't be ready yet:
	max14577 2-0025: Failed to read IRQ status: -5

extcon: max14577: Add support for MAX77836

2014-04-23T13:09:25+00:00

Add support for MAX77836 chipset to the max14577 extcon driver. The
MAX77836 MUIC has additional interrupts (VIDRM, ADC1K) so IRQ handling
is split up into two functions: max14577_parse_irq() and
max77836_parse_irq().

mfd: max77836: Add MAX77836 support to max14577 driver

2014-04-23T13:08:54+00:00

Add Maxim 77836 support to max14577 driver. The chipsets have same MUIC
component so the extcon, charger and regulators are almost the same. The
MAX77836 however has also PMIC and Fuel Gauge.

The MAX77836 uses three I2C slave addresses and has additional interrupts
(related to PMIC and Fuel Gauge). It has also Interrupt Source register,
just like MAX77686 and MAX77693.

The MAX77836 PMIC's TOPSYS and INTSRC interrupts are reported in the
PMIC block. The PMIC block has different I2C slave address and uses own
regmap so another regmap_irq_chip is needed.

Since we have two regmap_irq_chip, use shared interrupts on MAX77836.

This patch adds additional defines and functions to the max14577 MFD core
driver so the driver will handle both chipsets. Also this patch replaces
"0x1 << N" with BIT(N) in defines for register masks.
