The PMIC is often a dependency for other devices, so make sure
it's initialized early. While at it, merge the spi/i2c registration
into a single initcall and use IS_ENABLED instead of ifdefs.

Some boards have to initialize the PMIC before other devices can
be initialized. This requires three levels of initcalls: one level
in which the PMIC is probed, one in which the board can call mc13xxx_get()
and the third one to initialize the PMIC dependent devices.
Allow to register a callback which is called once the PMIC is initialized.
This way mc13xxx_get() is no longer necessary and the number of required
initcalls levels is reduced to two.

When a devicenode has invalid pinctrl settings then printing the
offending node helps debugging it.

RX DMA Head Descriptor Pointer can get 0 when there is a lot of traffic,
which results in a timeout error. A good way to provoke this error is by
sending lots of ARP requests. This patch makes sure that the RX DMA Head
Descriptor Pointer is set.
The origin driver, from which this is derived, already contains this fix.

Clock gates having the CLK_GATE_HIWORD_MASK flag set use the upper 16
bits of the register as a "write enable" mask for the value in the
lower 16 bits.

Provide minimal regulator support. Only supported operations are enabling
and disabling regulators. Association of devices with their regulators is
limited to devicetree only. If regulator support is disabled the API expands
to static inline stubs so consumers can still use the API.

When a mtd device can have bad blocks we want to create a
bb device, so do this automatically. This allows us to
drop bb device creation from the environment.

This refactors the code so that we get a mtd_add_bb which can

The devfs layer just adds an addition indirection between mtd
and the bb devices with no purpose. Drop it.

The upstream dts files do not contain the register shift. As
we have Omap specific init code anyway we can just set the register
shift from there instead of relying on the devicetree properties.
