The DTS nodes for all 4 instances of the i.MXRT1050/1060 LPSPI controller will be predefined in arch/arm/boot/dts/nxp/imx/imxrt1050.dtsior in arch/arm/boot/dts/nxp/imx/imxrt1060.dtsi. The clock driver for the i.MXRT1050/1060 SoC will be updated to support the LPSPI clocks. Interrupts and clocks will be defined in the DTS nodes according to the processor reference manual. All controllers will be configured to use the DMA. All the SPI nodes in the .dtsi file will be disabled by default.
