Dear Binson,

I am not aware of an official MCUXpresso SDK/System Manager driver named fsl_pcal6524.cfsl_pcal6524.h for the PCAL6524HEAZ. NXP Linux BSPs support the device through the standard Linux GPIO-expander driver using the PCA6524 device-tree compatible string. The i.MX95 19x19 EVK is a public example that uses the PCAL6524 as an I²C GPIO expander: https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/freescale/imx95-19x19-evk.dts

With Best Regards,

Jozef
