 * up to 2GB NAND flash
 * 1x miniPCIe socket (with USB)
 * HDMI out (micro-HDMI)
 * HDMI in (micro-HDMI) (currently supported by only vendor kernel)
 * TTL level I/O (supported by GW16111 breakout board):
  * I2C
  * 2x UART
  * CAN
  * 2x DIO (GPIO/PWM)
  * USB OTG

The recommendation for new dts files is to use a dual-license type scheme.

Please check imx6sl-warp for an example.
