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> --- arch/arm/boot/dts/aspeed-ast2500-evb.dts | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-)
