* Freescale Low Power SPI (LPSPI) for i.MX Required properties: - compatible : - "fsl,imx7ulp-spi" for LPSPI compatible with the one integrated on i.MX7ULP soc - "fsl,imx8qxp-spi" for LPSPI compatible with the one integrated on i.MX8QXP soc - reg : address and length of the lpspi master registers - interrupt-parent : core interrupt controller - interrupts : lpspi interrupt - clocks : lpspi clock specifier. Its number and order need to correspond to the value in clock-names. - clock-names : Corresponding to per clock and ipg clock in "clocks" respectively. In i.MX7ULP, it only has per clk, so use CLK_DUMMY to fill the "ipg" blank. - spi-slave : spi slave mode support. In slave mode, add this attribute without value. In master mode, remove it. Examples: lpspi2: lpspi@40290000 { compatible = "fsl,imx7ulp-spi"; reg = <0x40290000 0x10000>; interrupt-parent = <&intc>; interrupts = ; clocks = <&clks IMX7ULP_CLK_LPSPI2>, <&clks IMX7ULP_CLK_DUMMY>; clock-names = "per", "ipg"; spi-slave; };
