[PATCH 0/5] Add Core Divider clock support for Armada 370/XP

[Ezequiel Garcia]

This patchset adds support for a set of clocks available in Armada 370/XP
known as "Core Divider" clocks.

These are a set of gatable clocks, derived from a fixed PLL at
a configurable ratio. Although this patchset adds support for the more
general case, we only support one of the clocks, namely the NAND ECC clock.

With this infrastructure in place, the addition of the rest of the clocks
would be fairly easy.

In addition, the NAND clock is added as a fixed-ratio from the NAND ECC clock,
to model accurately the SoC clock tree.

A pictorical representation of the clock tree would be:

    PLL

    |
    ---------------------
    |			|
    |			|
    NAND ECC clock	...

    |
    NAND clock

This patchset is based on v3.12-rc2. Any opinions are highly appreciated.

Thanks!
