[PATCH 1/2] gpio: pca953x: Add support for TI TCA9535 variant

[PATCH 1/2] gpio: pca953x: Add support for TI TCA9535 variant

[Fabio Estevam]

Add support for the TI TCA9535 variant.

The NXP PCA9535 is already supported by the driver.

TCA9535 supports lower voltage operation (down to 1.65V VCC)
compared to PCA (down to 2.3V VCC).

From a software perspective, these models are equivalent as they
have the same register map.

[PATCH 2/2] dt-bindings: gpio: pca95xx: Document the TI TCA9535 variant

[Fabio Estevam]

The TI TCA9535 variant has the same programming model as the NXP PCA9535.

Document the "ti,tca9535" compatible string.
