22Example:
23
24qspi: qspi@4b300000 {
25	compatible = "ti,dra7xxx-qspi";
26	reg = <0x47900000 0x100>, <0x30000000 0x3ffffff>;
27	reg-names = "qspi_base", "qspi_mmap";
28	#address-cells = <1>;
29	#size-cells = <0>;
30	spi-max-frequency = <25000000>;
31	ti,hwmods = "qspi";
32};

34For dra7xx:
35qspi: qspi@4b300000 {
36	compatible = "ti,dra7xxx-qspi";
37	reg = <0x4b300000 0x100>,
38	      <0x5c000000 0x4000000>,
39	reg-names = "qspi_base", "qspi_mmap";
40	syscon-chipselects = <&scm_conf 0x558>;
41	#address-cells = <1>;
42	#size-cells = <0>;
43	spi-max-frequency = <48000000>;
44	ti,hwmods = "qspi";
