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- interrupt-parent: phandle for the interrupt gpio controller
10- interrupts: GPIO interrupt to which the chip is connected
11- lpcpd-gpios: Output GPIO pin used for ST33ZP24 power management D1/D2 state.
12If set, power must be present when the platform is going into sleep/hibernate mode.
13
14Optional SoC Specific Properties:
15- pinctrl-names: Contains only one value - "default".
16- pintctrl-0: Specifies the pin control groups used for this controller.
17
18Example (for ARM-based BeagleBoard xM with ST33ZP24 on I2C2):
19
20&i2c2 {
21
22 status = "okay";
23
24 st33zp24: st33zp24@13 {
25
26 compatible = "st,st33zp24-i2c";
27
28 reg = <0x13>;
29 clock-frequency = <400000>;
30
31 interrupt-parent = <&gpio5>;
32 interrupts = <7 IRQ_TYPE_LEVEL_HIGH>;
33
34 lpcpd-gpios = <&gpio5 15 GPIO_ACTIVE_HIGH>;
35 };
36};
