The platform bus_type .match callback attempts to match the platform device
name with an entry on the .id_table if provided and fallbacks to match with
the driver's name if a table is not provided.

Using a platform device ID to match is more explicit, allows the driver to
support more than one device and also the MODULE_DEVICE_TABLE macro can be
used to export the module aliases information instead of the MODULE_ALIAS.

Add an updated set of registers listed in the core regmap_range volatile
ranges defined for the DA9063.

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 DA9063 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.

The prcmu_config_clkout() function ensures that the 'clkout' argument
can only be '0' or '1' using an appropriate BUG_ON(), so the compiler
should know that the div_mask, mask, and bits variables are always
initialized later on. However, it doesn't understand this in gcc-5.2
and produces a false positive warning instead:

drivers/mfd/db8500-prcmu.c: In function 'prcmu_config_clkout':
drivers/mfd/db8500-prcmu.c:762:10: error: 'div_mask' may be used uninitialized in this function [-Werror=maybe-uninitialized]
  if (val & div_mask) {

drivers/mfd/db8500-prcmu.c:769:13: error: 'mask' may be used uninitialized in this function [-Werror=maybe-uninitialized]
    if ((val & mask & ~div_mask) != bits) {
             ^
drivers/mfd/db8500-prcmu.c:757:7: error: 'bits' may be used uninitialized in this function [-Werror=maybe-uninitialized]

Replacing the switch() statement with an equivalent if() lets
gcc figure this out reliably and avoids the warnings.

tps65010 driver's initcall cannot succeed when the driver is built-in,
because it expects that the I2C probe is completed at initcall time;
this cannot happen as MFD is initialized before I2C. Also on systems
where the chip is not present there is unnecessary 30 ms delay during
the boot.

Instead of waiting for probe to finish, just register the I2C device.
If some boards need retry mechanism for startup glitches, that should be
done in the actual probe function. Also delete the driver banner message.

The patch allows to use tps65010 again with OMAP1 (where it's required
to be built-in) and enables e.g. USB and LED functionality on OMAP5912 OSK.

The axp20x driver assumes the device is i2c based. This is not the
case with later chips, which use a proprietary 2 wire serial bus
by Allwinner called "Reduced Serial Bus".

This patch follows the example of mfd/wm831x and splits it into
an interface independent core, and an i2c specific glue layer.
MFD_AXP20X and the new MFD_AXP20X_I2C are changed to tristate
symbols, allowing the driver to be built as modules.

Whitespace and other style errors in the moved i2c specific code
have been fixed. Included but unused header files are removed as
well.

the axp20x driver into multiple ones covering different interface

Convert this driver to use clkdev_create() instead of
clk_register_clkdevs(). The latter API is only used by this driver,
although this driver only allocates one clk to add anyway.
Furthermore, this driver allocates the clk_lookup structure with
devm, but clkdev_drop() will free that structure when passed,
leading to a double free when this driver is removed. Clean it
all up and pave the way for the removal of clk_register_clkdevs().
