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.

Simplify probe() by replacing of_device_get_match_data() and ID lookup for
retrieving match data by i2c_get_match_data().
Some minor cleanups:
* Remove the trailing comma in the terminator entry for the ID
table making code robust against (theoretical) misrebases or other
similar things where the new entry goes _after_ the termination without
the compiler noticing.
* Move OF table near to the user.

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.

03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from

This patch removes the requirement for an IRQ, because for the core
functionality IRQ isn't needed. So this makes the DA9061/62 chip
usable for designs which haven't connected the IRQ pin.

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

The watchdog driver compatible is "dlg,da9062-watchdog" and not
"dlg,da9062-wdt". Therefore the mfd-core can't populate the of_node and

MFD support for DA9061 is provided as part of the DA9062 device driver.
The registers header file adds two new chip variant IDs defined in DA9061
and DA9062 hardware. The core header file adds new software enumerations
for listing the valid DA9061 IRQs and a da9062_compatible_types enumeration
for distinguishing between DA9061/62 devices in software.
The core source code adds a new .compatible of_device_id entry. This is
extended from DA9062 to support both "dlg,da9061" and "dlg,da9062". The
.data entry now holds a reference to the enumerated device type.
A new regmap_irq_chip model is added for DA9061 and this supports the new
list of regmap_irq entries. A new mfd_cell da9061_devs[] array lists the
new sub system components for DA9061. Support is added for a new DA9061
regmap_config which lists the correct readable, writable and volatile
ranges for this chip.
The probe function uses the device tree compatible string to switch on the
da9062_compatible_types and configure the correct mfd cells, irq chip and
regmap config.
Kconfig is updated to reflect support for DA9061 and DA9062 PMICs.

volatile lists
Add an updated set of registers listed in the core regmap_range volatile
ranges defined for the DA9062.
These new registers contain bits that cannot be considered under the full
control of software. Under various conditions the hardware will set and/or
automatically clear bit(s) contained in these registers.
When using a cached version of regmap, the volatility of these registers must
be identified otherwise the regmap operations may not ensure the registers
are explicitly altered.
As well as updating the list of volatile registers, this change will fix a
corner case discovered in the DA9063 ONKEY which is used by the DA9062 core.
In the ONKEY case, the CONTROL_B register is now listed as volatile in the
regmap_range because it contains the bit field NONKEY_LOCK. This bit can be
altered by hardware, in which case regmap must be notified of its ability
to be manpiulated outside of software control.
