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.

Setting mask_invert to false is pointless because that's the
default. The flag is also deprecated, so drop it.

6816c54bdd mfd: rohm-bd718x7: Convert to i2c's .probe_new()
The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.

316d0d92fb mfd: bd718x7: simplify by cleaning unnecessary device data
Most ROHM PMIC sub-devices only use the regmap pointer from
parent device. They can obtain this by dev_get_regamap so in
most cases the MFD device does not need to allocate and populate
the driver data. Simplify drivers by removing this.

The BD70528 still needs the access to watchdog mutex so keep
rohm_regmap_dev in use on BD70528 RTC and WDG drivers for now.

8c352e68dd mfd: bd718x7: Add compatible for BD71850
ROHM BD71850 PMIC is almost identical to BD71847. Main difference is some
initial voltage values for regulators. The BD71850 can be handled by
BD71847 driver but adding own compatible makes it clearer for one who
creates the DT for board containing this PMIC and allows SW to be
differentiating PMICs if needed.

1b1c26b24a mfd: Rohm PMICs: Use platform_device_id to match MFD sub-devices
Thanks to Stephen Boyd I today learned we can use platform_device_id
to do device and module matching for MFD sub-devices!

Do device matching using the platform_device_id instead of using
explicit module_aliases to load modules and custom parent-data field
to do module loading and sub-device matching.

e25547f899 mfd: bd718x7: Make power button press duration configurable
Allow overwriting the values in BD718XX_REG_PWRONCONFIG0 and
BD718XX_REG_PWRONCONFIG1 via devicetree. Read values in milliseconds and
attempt to round them to something supported by the hardware.

Keep existing values (from bootloader or OTP) if property is not
present.

2a87f09020 mfd: bd718x7: Remove hardcoded config for button press duration
The reset button on imx8mm-evk is tied to PWRON_B pin of bd71847 and the
long press duration is set to zero from OTP. The linux driver overrides
those values and breaks reset from button.

Overwriting OTP or bootloader configuration with some hardcoded defaults
is not desirable, keep already programmed values instead.

Split the bd718x7.h to ROHM common and bd718x7 specific parts
so that we do not need to add same things in every new ROHM
PMIC header. Please note that this change requires changes also
in bd718x7 sub-device drivers for regulators and clk.
