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.

[... and so on for the other groups ... ]

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

Current mainline has all groups under the iomux node which has the
effect that all possible groups are compiled into every dtb resulting in
very bloated dtbs. So Shawn changed it to what's currently in next, but
this hasn't been accepted by the dt maintainers. Now this series tries
to address the concerns of the dt maintainers by not using macros that
expand to other macros.

Yes, my for-next branch was excluded from linux-next temporarily for
some reason.  I will ask Stephen to add it back once v3.14-rc1 is out.
That said, you can see nothing we developed in this cycle on linux-next
for now.

No.  That will bring back the problem we try to solve from the
beginning [1].

Thanks for the pointer, I think I understand the issue now :-) .

So for the short term, I should probably also define the pingroups in my board-
dts then.


But as an insane idea that I just had, because the issue will probably affect 
more architectures at some point when their pingroups or other common-nodes 
grow, how about introducing something like a "/delete-if-unreferenced/" prefix 
in dtc?

As I could see in [0], adding something to dtc is not as far off as I thought.

In essence one would add the pingroups to the soc dtsi, like

		ecspi1 {
			/delete-if-unreferenced/ pinctrl_ecspi1_1: ecspi1grp-1 {
				fsl,pins = <
					MX6SL_PAD_ECSPI1_MISO__ECSPI1_MISO 0x100b1
					MX6SL_PAD_ECSPI1_MOSI__ECSPI1_MOSI 0x100b1
					MX6SL_PAD_ECSPI1_SCLK__ECSPI1_SCLK 0x100b1
				>;
			};
		};

and dtc would then be tasked with checking if the node gets referenced in a 
phandle somewhere in the dts and if not removing it.

I don't know if this is at all sane to think about or doable in dtc.
