Other Parts Discussed in Thread: TCA6408A

Hi Expert:

We have Automotive Car infotainment project has design in TCA6408A-Q1 IO expander for MTK SoC linux driver .

The Linux driver Kernel 5.15 version called gpio-pca953x.c and could support TCA6408A IO expander.

Because I’m not Software base FAE. Do you have Linux driver GPIO configuration guideline of the part can help quickly support customer ?

thank you .

The device tree entry would look like this:

tca6408: tca6408@20 {
  compatible = "tca6408";
  reg = <0x20>;
};
