Hi

Could somebody clarify which linux driver to use for the the PF1550 with the iMX6ULZ and where I can find an example device tree binding.

Thanks

I too would like to know what the status of the PF1550 driver is.

Hello,

  PMIC PF1550 is supported by NXP Linux BSP.  Use section 2.5.2 (PMIC PF Regulator)

of i.MX Linux Reference Manual (Rev. L5.4.24_2.1.0) for more details.

Embedded Linux for i.MX Applications Processors | NXP

Yuri.

Hi

In L5.4.24_2.1.0 I see the pf1550-regulator-rpmsg driver but not the pf1550 client driver. I just checked and the client driver was available in the 4.19.35_1.1.0 release (pf1550.c) but has been removed in latest BSP. I also noticed the pf1550 charger driver was removed in the latest release, pf1550-charger.c in /drivers/power/supply. 

Do I have to use the rpmsg drive now, even in a iMX6ULZ application? What about the battery charger driver as that has now been removed?

Thanks

Ian

Hello,

  Yes, It has been removed from  L5.4.24_2.1.0 release. However, if customers are using pf1550 with i.MX6ULZ then they can still port/integrate those drivers in their BSP. The BSP team has been requested about  reasons behind the removal of the driver; I will inform You  in case of an update.

Yuri.
