* STMicroelectronics SAS. ST33ZP24 TPM SoC
Required properties:
- compatible: Should be "st,st33zp24-spi".
- spi-max-frequency: Maximum SPI frequency (<= 10000000).
Optional ST33ZP24 Properties:
- interrupt-parent: phandle for the interrupt gpio controller
- interrupts: GPIO interrupt to which the chip is connected
- lpcpd-gpios: Output GPIO pin used for ST33ZP24 power management D1/D2 state.
If set, power must be present when the platform is going into sleep/hibernate mode.
Optional SoC Specific Properties:
- pinctrl-names: Contains only one value - "default".
- pintctrl-0: Specifies the pin control groups used for this controller.
Example (for ARM-based BeagleBoard xM with ST33ZP24 on SPI4):
&mcspi4 {
st33zp24@0 {
compatible = "st,st33zp24-spi";
spi-max-frequency = <10000000>;
interrupt-parent = <&gpio5>;
interrupts = <7 IRQ_TYPE_LEVEL_HIGH>;
lpcpd-gpios = <&gpio5 15 GPIO_ACTIVE_HIGH>;
};
};
