This describes the basic hierarchy of picoxcell pc3x3 devices including clocks and bus interconnect. Some onchip devices are currently omitted as there haven't been bindings created for them. v2: - change timer compatible strings to be more soc specific - split vic node into 2 devices Signed-off-by: Jamie Iles <jamie@jamieiles.com>
