1* STMicroelectronics SAS. ST33ZP24 TPM SoC
2
3Required properties:
4- compatible: Should be "st,st33zp24-i2c".
5- clock-frequency: I²C work frequency.
6- reg: address on the bus
7
8Optional ST33ZP24 Properties:
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 I2C2):
18
19&i2c2 {
20
21
22 st33zp24: st33zp24@13 {
23
24 compatible = "st,st33zp24-i2c";
25
26 reg = <0x13>;
27 clock-frequency = <400000>;
28
29 interrupt-parent = <&gpio5>;
30 interrupts = <7 IRQ_TYPE_LEVEL_HIGH>;
31
32 lpcpd-gpios = <&gpio5 15 GPIO_ACTIVE_HIGH>;
33 };
34};
