> Add support for the DH electronics i.MX6DL DHCOM SoM and a PDK2 evaluation
> board. The evaluation board features three serial ports, USB OTG, USB host
> with an USB hub, Fast or Gigabit ethernet, eMMC, uSD, SD, analog audio,
> PCIe and HDMI video output.
> 
> All of the aforementioned features except for mSATA are supported, mSATA
> is not available on i.MX6DL and is only available on DHCOM populated with
> i.MX6Q SoC which is already supported upstream.
