Linux/PCA9535: PCA9535 and TCA9535

Part Number: PCA9535
Other Parts Discussed in Thread: TCA9535,

Tool/software: Linux

Hi Sir,

I know TCA9535 has the same register maps and address as the PCA9535. The software does not need to be changed going from PCA9535 to TCA9535.

and the main difference between PCA9535 and TCA9535:

• TCA supports lower voltage operation (down to 1.65V VCC) compared to PCA (down to 2.3V VCC)
• TCA has improved POR circuit which supports different power supply ramps. PCA has limitation on power supply ramping rates

my problem is does TCA9535  pin compatible with the PCA9535 ? and can use PCA9535 's seeting in Linux DTS?

http://elixir.free-electrons.com/linux/v3.18/source/Documentation/devicetree/bindings/gpio/gpio-pca953x.txt

like

       gpio@20 {

              compatible = "nxp,pca9505";

              reg = <0x20>;

              pinctrl-names = "default";

              pinctrl-0 = <&pinctrl_pca9505>;

              interrupt-parent = <&gpio3>;

              interrupts = <23 IRQ_TYPE_LEVEL_LOW>;

       };

thanks~

Best Regards,
