[Lu Yangbo-B47093] Hi Uffe, I agree.
These patches are based on Shawn's tree which has the latest layerscape board dts.
Actually I'm not sure which git tree I should send these patches to according to MAINTAINERS, but I saw Shawn had merged some layerscape board dts before.

Hi Shawn,
Am I right to send these patches to you for reviewing? Which git tree do you recommend I should send these patches to?

Thanks.
