Looking for PMIX PF1550 mfd kernel driver (imx_5.4.47_2.2.0)

1,019 Views

I am using the kernel on branch imx_5.4.47_2.2.0 from https://source.codeaurora.org/external/imx/linux-imx.git for a iMX6ULL SOC.

Yet there is no driver for the PF1550 PMIC ?

Searching the internet some kernel patches can be found.

Yet I wonder if there is some "official" driver for this FSL PMIC ?

Thanks Thomas

Hi thomasritter ,

There is no pf1550 driver in L5.4.x BSP, but it's driver is supported in L4.19.35_1.1.0 : drivers/regulator/pf1550.c

and it is supported in device tree for i.MX6UL: arch/arm/boot/dts/imx6ul-14x14-evk-pf1550.dts

so you can port it to L5.4.x BSP.

Hope this information is helpful to you.

Have a nice day!
