5549eeedcd mfd: rohm-bd71828: Add power off functionality
Since the chip can power off the system, add the corresponding
functionality.
Based on https://github.com/kobolabs/Kobo-Reader/raw/master/hw/imx6sll-clara2e/kernel.tar.bz2

6c93d55554 mfd: rohm: Convert to use maple tree register cache
The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache.

dc0c386e09 mfd: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

9816d85923 mfd: Switch i2c drivers back to use .probe()
After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

cb83cb0dfa mfd: rohm: Use dev_err_probe()
The dev_err_probe() has (at least) following benefits over dev_err()
when printing an error print for a failed function call at a device
driver probe:
	- Omit error level print if error is 'EPRBE_DEFER'
	- Standardized print format for returned error
	- return the error value allowing shortening calls like:

	if (ret) {
		dev_err(...);
		return ret;
	}

	to

	if (ret)
		return dev_err_probe(...);

Convert the ROHM BD71828, ROHM BD718x7 and ROHM BD9576 core drivers to
use the dev_err_probe() when returned error is not hard-coded constant.

cdbecc4c44 mfd: rohm-bd71828: Replace irqchip mask_invert with unmask_base
Remove use of the deprecated mask_invert flag. Inverted mask
registers (where a '1' bit enables an IRQ) can be described more
directly as an unmask register.

1c743ad523 mfd: bd71828: Support ROHM BD71828 PMIC - core
BD71828GW is a single-chip power management IC for battery-powered portable
devices. The IC integrates 7 buck converters, 7 LDOs, and a 1500 mA
single-cell linear charger. Also included is a Coulomb counter, a real-time
clock (RTC), 3 GPO/regulator control pins, HALL input and a 32.768 kHz
clock gate.

Add MFD core driver providing interrupt controller facilities and i2c
access to sub device drivers.
