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- interrupts: GPIO interrupt to which the chip is connected
9- lpcpd-gpios: Output GPIO pin used for ST33ZP24 power management D1/D2 state.
10If set, power must be present when the platform is going into sleep/hibernate mode.
11
12Optional SoC Specific Properties:
13- pinctrl-names: Contains only one value - "default".
14- pintctrl-0: Specifies the pin control groups used for this controller.
