Linux/TCA6507: TCA6507 device ID

Part Number: TCA6507

Tool/software: Linux

Hi INT team,

My cutomer are using TCA6507 to  drive RGB LEDs, they want to read the device ID so that they can monitor any device version change in future, this is a standard procedure in their drive code. I can't find the device ID register in the datasheet, could you help to confirm if there's a way to read out the ID version?

thanks

Luke
