    1 * STMicroelectronics SAS. ST33ZP24 TPM SoC
    2 
    3 Required properties:
    4 - compatible: Should be "st,st33zp24-spi".
    5 - spi-max-frequency: Maximum SPI frequency (<= 10000000).
    6 
    7 Optional 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.
   10 If set, power must be present when the platform is going into sleep/hibernate mode.
   11 
   12 Optional SoC Specific Properties:
   13 - pinctrl-names: Contains only one value - "default".
   14 - pintctrl-0: Specifies the pin control groups used for this controller.
   15 
   16 Example (for ARM-based BeagleBoard xM with ST33ZP24 on SPI4):
   17 
   18 &mcspi4 {
   19 
   20 
   21         st33zp24@0 {
   22 
   23                 compatible = "st,st33zp24-spi";
   24 
   25                 spi-max-frequency = <10000000>;
   26 
   27                 interrupt-parent = <&gpio5>;
   28                 interrupts = <7 IRQ_TYPE_LEVEL_HIGH>;
   29 
   30                 lpcpd-gpios = <&gpio5 15 GPIO_ACTIVE_HIGH>;
   31         };
   32 };
