MFC r282516:

Add the code necessary to run the imx6 chip at its lowest clock/power
operating point (396MHz/950mV).

MFC r268838, r277644:

Add support for Toradex Apalis i.MX6 development board.

Add support for imx6 audio transmitting, include drivers for:
o Digital Audio Multiplexer (AUDMUX)
o Smart Direct Memory Access Controller (SDMA)
o Synchronous Serial Interface (SSI)

MFC r277555, r277568:

Enable all sd device clocks on imx6.

Add imx5/6 pinmux driver support for encoded input register configs.

MFC r273353, r273514:

Attach the imx6 CCM driver during BUS_PASS_CPU.

Unconditionally enable the clocks for all imx6 devices that we have drivers
for, or that are required to run the chip (such as busses).

MFC r271055, r271084, r271094:

Add a function to get the frequency of the AHB bus. Another stopgap
function until we have full clock support for imx6.

The imx5x and imx6 chips have an onboard IOMUX device which also contains a
few "general purpose registers" whose values control chip behavior in ways
that have nothing to do with IO pin mux control. Define a simple API that
other soc-specific code can use to read and write the registers, and provide
the imx51 implementation of them.

Fix a typo.

MFC 264977:

Stop calling imx51_ccm_foo() clock functions from imx6 code. Instead
define a few imx_ccm_foo() functions that are implemented by the imx51
or imx6 ccm code.

r262585, r262587, r262696, r262712

Replace many pasted identical definitions of cpu_initclocks() with a common
implementation in arm/machdep.c.

aicasm: Don't complain about missing prototypes to ease bootstrap issues.

Vybrid: Add driver for Inter-Integrated Circuit (I2C).

imx6: Initialize the Low Power Mode bits to keep the ARM cores running
during WFI.

All our current ARM multi-core systems have all cores in one package with
a shared L2 cache, reflect that in the common cpu_topo() routine.

mpcore timer: Supply a DELAY() implementation via weak linkage, so that
SoC-specific code can supply a better implementation.

imx6: Add some rudimentary voltage control.

Add an armv7 implementation of cpu_sleep().

Add __used attribute so that the DELAY implementation doesn't get
optimized away as unreferenced, causing linker errors when trying to
resolve the weak reference to the missing function.

MFC r261410

Follow r261352 by updating all drivers which are children of simplebus
to check the status property in their probe routines.

MFC r257453: Add stubbed-out imx6 support for clocks and power management.
