J722SXH01EVM: unable to find PMIC configuration in device tree of TDA4AEN (J722S 10.0 SDK)

Hello Prathyusha,

What is the use case with PMIC? I want to understand the requirement before i check with the team internally. 

Best Regards,

Hi, Keerthy

Actually I want to use PMIC configuration on my custom board which uses the J722S Soc. So, I want to know how PMIC (TPS65223) is configured in U-boot for TDA4AEN (J722S 10.0 SDK), But I am unable to find any device tree entry for PMIC (TPS65223). 

Thanks & Regards

Hi Prathyusha,

I double checked & there is no software support in the U-Boot. I want to know what is that you want to program w.r.t PMIC?

Hi, Keerthy

In general, PMIC is configured in device tree, but In U-Boot  for TDA4AEN (J722S 10.0 SDK) here the PMIC configured hardware IC  is TPS65223 I got this info(i.e PMIC hardware IC  as TPS65223) from datasheet. But I'm unable to find the TPS65223 in any of the device tree related to PMIC, could you please help me with this. could please point me where I can find the TPS65223 in PMIC device tree.

If TPS65223 is not the appropriate hardware IC  for PMIC then what is hardware IC that is configured for PMIC?

Thanks & Regards

There are references for TPS65224.
