This series of patches update mvmdio for Armada 8k CP110. A number of
issues were found:
1. The driver fails to disable an interrupt when something goes wrong
in the probe function.
2. The interrupt is specified in DT to be optional, but the driver
unconditionally writes to the interrupt mask register, which may
not exist.
3. The DT binding specifies
"reg: address and length of the SMI register"
however, when supporting the interrupt, the size must cover the
interrupt register as well. Update the binding documentation
with this information that was previously omitted.
4. If the register size is too small, have the driver print an error
and disable use of the interrupt.
5. Armada 8k needs three clocks for the MDIO interface, otherwise the
SoC hangs (since it is part of one of the ethernet interfaces.)
GOP clock, MG core clock and MG clock are needed on 8k. Augment the
binding and driver to allow three clocks to be specified.
