ARM: dts: aspeed: Enable vhub on port A of AST2500 EVB
This is an eval board, it makes sense to enable many functions by default. This changes the device-tree to set port A to be a USB device and leave port B as a host, along with a little comment explaining how to change it. (the vhub device can only exist on port A on this SoC) Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Acked-by: Andrew Jeffery <andrew@aj.id.au> Signed-off-by: Joel Stanley <joel@jms.id.au>
