No pinctrl log in dmesg on kernel 3.14.28

[chaitanyadhere]

Hello all,

               We are writing a dts file for our custom board based on imx6q derived from Freescale i.MX6 Quad Armadillo2 Board. Ther kenel version is 3.14.28. The board boots up, but in dmesg, we are getting the following log:

Is it normal for each and every sub-system  / peripheral of the SoC to show the log: no default pinctrl state ?

Currently, my dts file is almost same as Armadillo2 Board's dts file except a few of my board specific changes.

Am I missing something in the dts tree due to which I'm getting no default pinctrl state ?

Thanks,

Hi,

Are you using the pinctrl-names property in the nodes you are getting the messages?

        pinctrl-names = "default";

Best Regards,

Alejandro
