The Snowball Board's Ethernet chip is configured in a slightly
non-standard way. Its SoC has an address space usually reserved
for a NOR-flash device. However, on the Snowball, that external
bus is populated by the SMSC9115 Ethernet chip. So, to power on
the Ethernet chip, we have to enable the GPIO controlled
regulator which usually controls the NOR-flash. In this patch
we inform the Snowball's Device Tree which GPIO is used to
operate it.

I guess you will funnel this to ARM SoC with other DT patches?
Yours,
