请问能否提供PCAL6524HEAZ的系统管理器驱动程序代码？
fsl_pcal6524.c
fsl_pcal6524.h
亲爱的宾森：
我不知道有名为fsl_pcal6524.cfsl_pcal6524.hf或 PCAL6524HEAZ 的官方 MCUXpresso SDK/系统管理器驱动程序。NXP Linux BSP 通过标准的 Linux GPIO 扩展器驱动程序，使用 PCA6524 设备树兼容字符串来支持该设备。i.MX95 19x19 EVK 是一个公开示例，它使用 PCAL6524 作为 I²C GPIO 扩展器： https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/freescale/imx95-19x19-evk.dts
最诚挚的问候，
约瑟夫
