Hello,
this the second version of a series allowing to use the switch component of the Ocelots SoC as a network interface.
The binding used is exactly the same of the one already used by Linux.
There is also a patch adding a workaround needed on the Ocelot based boards: indeed the pin connected to the DDR reset is part of the switch subsystem. So we need ensure that the DDR is not reset during the switch reset.
Gregory
Changelog: v1 -> v2: - Use wait_for_bit_le32() (suggested by Stefan Roese) - Use debug() instead of printf() for the debug messages in mscc_switch_reset.
