DM8168 AVS: TPS40400 PMIC driver for PMbus/I2C?

Hi Lo,

According to the below E2E discussion, the TPS40400 driver is available for DVR RDK, not for EZSDK.

Hi Lo,

These 3 patches are for the DVR RDK, not for EZSDK.

The patches for EZSDK are located here:

Hi Pavel,

the EZSDK patches do not include the tps40400 driver (e.g. driver/regulator/tps40400-regulator.c).

I think it's possible to integrate the DVR RDK tps40400 driver into the EZSDK kernel.

Regards,

Lo

Lo,

Do you know if anyone has successfully made the EZSDK work with the TSP40400 driver?

Thanks!

Hello Tate,

yes the design works, afaik you still need to patch the default EZSDK kernel.

Regards,

Lo
