- clock-names: Should be "clk_apb5".
- pinctrl-names : a pinctrl state named "default" must be defined.
- pinctrl-0 : phandle referencing pin configuration of the device.
- resets : phandle to the reset control for this device.
- cs-gpios: Specifies the gpio pins to be used for chipselects.

- clock-frequency : Input clock frequency to the PSPI block in Hz.
Default is 25000000 Hz.
Aliases:
- All the SPI controller nodes should be represented in the aliases node using
the following format 'spi{n}' withe the correct numbered in "aliases" node.
Example:
aliases {
spi0 = &spi0;
};
spi0: spi@f0200000 {
compatible = "nuvoton,npcm750-pspi";
