TDA4VM: power down and reboot the TDA4 system

Hi Vadivel,

If intent is driving a Reset from the A72, the TISCI Reset API, TISCI PM System Reset API Documentation — TISCI User Guide, may be of interest to you.

If intent is to remove power from the TDA4 Device, then perhaps you're looking at I2C commands to a PMIC, or some other communication to PMIC, to let the PMIC know to power down the TDA4 device.   

Regards,

Thanks KB!

Please can you provide I2C command?  

Is there System Power Management Interface(SPMI) protocol supported? document.

Is there any sample for these (TISCI-PM, I2C & SPMI)?

Regards, 

Vadivel

please can someone help me on this?

Hi,

Poweroff is currently not supported. So you will need to develop a PMIC driver to support I2C writes to power off the PMIC upon poweroff command
from Linux user space.

Thanks Keerthy! Is it reboot or restart is supported? Let me know what are things supported PMIC related? from linux user space (A72).

Thanks Keerthy! Is it possible to send(use) PMIC((TISCI-PM) related API's from R5F?

Thanks Keerthy! for your information.
