Patch for PF1510 for Linux

Hi,

We would like to use PF1510 for our implementation with IMX6ULL.

However, we noticed there is no driver available for this chip in Linux.

I found that the PF1550/PF1510 driver has been removed from the kernel:

https://community.nxp.com/t5/Power-Management/Linux-driver-for-PF1550-and-iMX6ULZ/td-p/1059763 

I can only find pf1550-regulator-rpmsg.c in my kernel (im using NXP release 5.4.47_2.2.0 ).

 

I found in application note AN12922 that there is a patch available:

https://www.nxp.com/docs/en/application-note/AN12992.pdf 

 

I was wondering where I would be able to find this patch, and if is different from the version in Linux NXP release 4.19.35_1.1.0 (pf1550.c) mentioned in the above post.

Hi @r_veens ,

There's no existing patch about PF1510 enablement in i.MX6ULL. PF1510 driver can reuse the PF1550 driver. Cause PF1510 only removed charging function from PF1550.

You can refer to imx6ul-14x14-evk-pf1550.dts and pf1550.c file in former Linux BSP.
