1* STMicroelectronics SAS. ST33ZP24 TPM SoC
2
3Required properties:
4- compatible: Should be "st,st33zp24-spi".
5- spi-max-frequency: Maximum SPI frequency (<= 10000000).
6
7Optional ST33ZP24 Properties:
8- interrupt-parent: phandle for the interrupt gpio controller
9- interrupts: GPIO interrupt to which the chip is connected
10- lpcpd-gpios: Output GPIO pin used for ST33ZP24 power management D1/D2 state.
11If set, power must be present when the platform is going into sleep/hibernate mode.
12
13Optional SoC Specific Properties:
14- pinctrl-names: Contains only one value - "default".
15- pintctrl-0: Specifies the pin control groups used for this controller.

17Example (for ARM-based BeagleBoard xM with ST33ZP24 on SPI4):
18
19&mcspi4 {
20
21        status = "okay";
22
23        st33zp24@0 {
24
25                compatible = "st,st33zp24-spi";
26
27                spi-max-frequency = <10000000>;
28
29                interrupt-parent = <&gpio5>;
30                interrupts = <7 IRQ_TYPE_LEVEL_HIGH>;
31
32                lpcpd-gpios = <&gpio5 15 GPIO_ACTIVE_HIGH>;
33        };
34};
