mfd: max77686: Correct tab-based alignment of register addresses

2021-11-05T14:40:27+00:00

Some lines have an extra tab, remove them for proper visual alignment as
present on the rest of this file.

rtc: max77686: move initialisation of rtc regmap, irq chip locally

2016-03-14T16:08:13+00:00

To make RTC block of MAX77686/MAX77802 as independent driver,
move the registration of i2c device, regmap for register access
and irq_chip for interrupt support inside the RTC driver.
Removed the same initialisation from MFD driver.

Having this change will allow to reuse this driver for different
PMIC/devices from Maxim Semiconductor if they kept same RTC IP on
different PMIC. Some of examples as PMIC MAX77620, MAX20024 where
same RTC IP used and hence driver for these chips will use this
driver only for RTC support.

mfd: max77686/802: Remove support for board files

2015-01-22T16:03:55+00:00

The driver is used only on Exynos based boards with DTS support.
After removal of board file support from max77686 and max77802 regulator
drivers, the MFD driver can be converted to DTS-only version. This
simplifies a little the code:
1. No dead (unused) entries in platform_data structure.
2. More code removed.
3. Regulator driver does not depend on allocated memory
   from MFD driver.
4. It makes also easier extending the regulator driver.

Add to the max77686 MFD driver dependency on CONFIG_OF because without
DTS the regulator drivers (max77686 and max77802) won't bind.

mfd: max77686: Add Maxim 77802 PMIC support

2014-07-25T14:31:48+00:00

Maxim MAX77802 is a power management chip that contains 10 high
efficiency Buck regulators, 32 Low-dropout (LDO) regulators used
to power up application processors and peripherals, a 2-channel
32kHz clock outputs, a Real-Time-Clock (RTC) and a I2C interface
to program the individual regulators, clocks outputs and the RTC.

This patch adds support for MAX77802 to the MAX77686 driver and is
based on a driver added to the Chrome OS kernel 3.8 by Simon Glass.

mfd: max77686: Convert to use regmap_irq

2014-07-21T15:54:26+00:00

By using the generic IRQ support in the Register map API, it
is possible to get rid max77686-irq.c and simplify the code.

mfd: Add Maxim 77686 driver

2012-07-08T22:16:07+00:00

This patch is device driver for MAX77686 chip.
MAX77686 is PMIC and includes regulator and rtc on it.
This driver is core of MAX77686 chip, so provides common support for
accessing on-chip devices. It uses irq_domain to manage irq and regmap
to read/write data to its register with i2c bus.
