[PATCH 1/3] ARM: sti: stih416: Add support for B2020 RevE

[Lee Jones]

The B2020 RevE differs from the other B2020 boards in a few subtle ways;
including the Ethernet reset GPIO which this patch adds support for and
the LED wiring which will follow in a latter patch.  Without supplying
these differences Ethernet and the board LEDs simply will not work.

[PATCH 2/3] ARM: sti: stih416: Enable board LED support for B2020 RevE

[Lee Jones]

There are two LEDs available on the B2020 RevE board, one red, one
green.  In this patch we enable the red one for "heartbeat" and turn
the green one off.

[PATCH 3/3] ARM: sti: stih41x: Provide a proper header for this DTSI file

[Lee Jones]

Also explicitly include STiH416 Clk bindings instead of relying on
inheriting them from other DTSI files which we happen to include.

Nack.
As discussed on IRC, this dtsi file is included by stih415.dtsi.
In this case, we want to include stih415-clocks.dtsi instead.
