Hi Naveen,

What specifically do you need when you say "software device driver?"

Hi Naveen,

We do not have a linux device driver for this device TCA6424A.

There is some linux source code for PCA953x: https://git.ti.com/cgit/keystone-linux/linux/tree/drivers/gpio/pca953x.c?id=d1c057e31734426ba385e02291d97bdf06ba0c1d

You might be able to reference this material when looking at the TCA6424A. The registers writes and reads should be the same. The addresses will change because TCA6424A is a 24-bit device as opposed to a 16-bit or 8-bit IO expander.

Regards,

Tyler

Thanks for the responseTyler. We will take a look at it.

We are also looking drivers for TPS25751DREFR and ADS7128IRTET as well.

Please suggest.

Thanks,

Hi Naveen,

My team supports the TCA6424A.

For TPS25751DREFR, I will re-assign this thread.

For ADS7128 - this is the ADC team. It might be quicker for you to submit a new e2e thread specifically for this device while the TPS25751 is looked at from the other product line.

Regards,

Tyler

Hi Naveen,

We do not have drivers for TPS25751DREFER, however you can refer to this repository as reference: https://github.com/RPTST/tps25750

The PD device used here (TPS25750) is the predecessor to TPS25751 and has the same I2C writes and reads. There are some differences in the registers (TPS25751 has more configurability compared to TPS25750) so you will need to refer to the TPS25751 Technical Reference Manual for the full host interface.

Let us know if you have any further questions or concerns!

Thanks and Regards,

Raymond Lin
