H A Dst33zp24-spi.txt4 - compatible: Should be "st,st33zp24-spi".
5 - spi-max-frequency: Maximum SPI frequency (<= 10000000).
8 - interrupts: GPIO interrupt to which the chip is connected
9 - lpcpd-gpios: Output GPIO pin used for ST33ZP24 power management D1/D2 state.
13 - pinctrl-names: Contains only one value - "default".
14 - pintctrl-0: Specifies the pin control groups used for this controller.
16 Example (for ARM-based BeagleBoard xM with ST33ZP24 on SPI4):
23 compatible = "st,st33zp24-spi";
25 spi-max-frequency = <10000000>;
27 interrupt-parent = <&gpio5>;

5 - clock-frequency: I²C work frequency.
6 - reg: address on the bus
9 - interrupts: GPIO interrupt to which the chip is connected
10 - lpcpd-gpios: Output GPIO pin used for ST33ZP24 power management D1/D2 state.
14 - pinctrl-names: Contains only one value - "default".
15 - pintctrl-0: Specifies the pin control groups used for this controller.
17 Example (for ARM-based BeagleBoard xM with ST33ZP24 on I2C2):
24 compatible = "st,st33zp24-i2c";
