The Armada SoC family implementation of this SPI hardware module has
extended the configuration register to allow for a wider range of SPI
clock rates. Specifically the Serial Baud Rate Pre-selection bits in the
SPI Interface Configuration Register now also use bits 6 and 7 as well.

Modify the baud rate calculation to handle these differences for the
Armada case. Potentially a baud rate can be setup using a number of
different pre-scalar and scalar combinations. This code tries all
possible pre-scalar divisors (8 in total) to try and find the most
accurate set.

This change introduces (and documents) a new device tree compatible
device name "armada-370-spi" to support this.

Silergy SYR82x regulators share the exact same functionality and register layout
as the Fairchild FAN53555 regulators. Therefore extend the driver to add
support for them.

Both types use the same vendor id in their ID1 register, so it's not possible
to distinguish them automatically.

Similarly, the types also do not match. Type 8 used by the SYR827 and SYR828
start at 712.5mV and increment in 12.5mv steps, while the FAN53555 type 8
starts at 600mV and increments in 10mV steps.

using LVDS channel 1 on an i.MX53 leads to following error:

imx-ldb 53fa8008.ldb: unable to set di0 parent clock to ldb_di1

This comes from imx_ldb_set_clock with mux = 0. Mux parameter must be "1" for
reparenting di1 clock to ldb_di1. The value of the mux param comes from device
tree port settings.

On i.MX5, the internal two-input-multiplexer is used. Due to hardware limitations,
only one port (port@[0,1]) can be used for each channel (lvds-channel@[0,1],
respectively)

The quite-recently-added analog-tv-connector bindings say that the
compatible string for composite video connector is
"composite-connector". That string is also used in the omap3-n900.dts
file. However, the connector driver uses "composite-video-connector", so
this has never worked.

While changing the driver's compatible string to "composite-connector"
would be safer, as published DT bindings should not be changed, I'd
rather fix the bindings in this case for two reasons:

* composite-connector is a bit too generic name, as it doesn't even hint
  at video.
* it's clear that this has never worked, which means no one has used
  those bindings, which should make it safe to change this.

The PTP reference clock, used for setting the addend in the Timestamp Addend
Register, was erroneously hard-coded (as reported in the databook just as
example).

The patch removes the macro named: STMMAC_SYSCLOCK and allows to use a
reference clock (clk_ptp_ref_i) that can be passed from the platform.

If not passed, the main driver clock will be used as default; note that
this can be fine on some platforms.

Note that, prior this patch, using the old STMMAC_SYSCLOCK on some platforms,
as side effect, the ptp clock can move faster/slower than the system clock.

For v3.14 and prior, 1-bit Hamming code ECC via software was the

to use 1-bit Hamming code via Hardware using a different ECC layout
i.e. (ROM code layout) than what is used by software ECC.

This ECC layout change causes NAND filesystems created in v3.14
