Hi Shawn,

We created the pingrp macros in imx6sl-pingrp.h for purpose of less LOC
when same pin group is used by multiple boards.  However, DT maintainers
take it as an abuse of DTC macro support.  So let's get rid of it to
make the pins used by given device more intuitive.

I'm confused now :-) . Current linux-next [0] shows the pin-settings as part 
of imx6sl.dtsi - a way a lot of other architectures organize their pingroups 
too, with the board file only referencing the relevant pingroups from the 
predefined ones of the soc.

So I guess your move to the pingrp-header moved them out of the imx6sl.dtsi to 
the .h and is not part of linux-next; but this patch (and the others in this 
series) now moves the definitions into the individual board files. Can't you 
just move them back to the soc-dtsi files to prevent each board duplicating 
them?

Or I've simply missed previous discussions about this ;-) .


Thanks
Heiko
