The imx6q-kp.dtsi is defined in the Linux kernel [1].
However, not all features - like backlight, CAN, etc. are needed in
U-Boot. To reduce SPL footprint, as the TPC70 is the first
board (from i.MX6Q family of SoCs) which uses only DM in SPL and U-Boot
proper, only the necessary subset of [1] was added to U-Boot.
Note:
