* NXP PCA953x I2C GPIO multiplexer Required properties: - compatible: Has to contain one of the following: nxp,pca6416 nxp,pca9505 nxp,pca9534 nxp,pca9535 nxp,pca9536 nxp,pca9537 nxp,pca9538 nxp,pca9539 nxp,pca9554 nxp,pca9555 nxp,pca9556 nxp,pca9557 nxp,pca9574 nxp,pca9575 nxp,pca9698 nxp,pcal6416 nxp,pcal6524 nxp,pcal9535 nxp,pcal9555a maxim,max7310 maxim,max7312 maxim,max7313 maxim,max7315 ti,pca6107 ti,pca9536 ti,tca6408 ti,tca6416 ti,tca6424 ti,tca9539 ti,tca9554 onnn,cat9554 onnn,pca9654 exar,xra1202 - gpio-controller: if used as gpio expander. - #gpio-cells: if used as gpio expander. - interrupt-controller: if to be used as interrupt expander. - #interrupt-cells: if to be used as interrupt expander. Optional properties: - interrupts: interrupt specifier for the device's interrupt output. - reset-gpios: GPIO specification for the RESET input. This is an active low signal to the PCA953x. - vcc-supply: power supply regulator.
