Yup.

Good question.  Per board/solidrun/mx6cuboxi/mx6cuboxi.c:
/*
 * This is not a perfect match. Avoid dependency on the DM GPIO driver
 * needed
 * for accurate board detection. Hummingboard2 DT is good enough for
 * U-Boot on
 * all Hummingboard/Cubox-i platforms.
 */
so arch/arm/dts/imx6dl-hummingboard2-emmc-som-v15.dts is the base.  But
the board really is the original hummingboard platform.  Thanks!
