1 * Freescale Low Power SPI (LPSPI) for i.MX
5 - "fsl,imx7ulp-spi" for LPSPI compatible with the one integrated on i.MX7ULP soc
6 - "fsl,imx8qxp-spi" for LPSPI compatible with the one integrated on i.MX8QXP soc
7 - reg : address and length of the lpspi master registers
8 - interrupt-parent : core interrupt controller
9 - interrupts : lpspi interrupt
10 - clocks : lpspi clock specifier. Its number and order need to correspond to the
12 - clock-names : Corresponding to per clock and ipg clock in "clocks"
13 respectively. In i.MX7ULP, it only has per clk, so use CLK_DUMMY
14 to fill the "ipg" blank.
15 - spi-slave : spi slave mode support. In slave mode, add this attribute without
16 value. In master mode, remove it.
