[PATCH 0/3] dtc handling unreferenced nodes and an imx board dts

[Heiko Stübner]

After showcasing my dtc change as RFC before, this series shows essentially
where I want to go with the whole change - adding support for our ereaders
without duplicating the generic pinconfig nodes :-) . And also provides with
the dt change a user for the dtc flag addition.

That being said, the dtc change might need a bit more review and I also don't
know if it should go through the scripts/dtc variant like this or some
upstream and how the *_shipped files should be handled.

The patchset is done against linux-next from today, which includes both the
pingroups moved to the individual board files and the bindings for the zforce
touchscreen.

Heiko Stuebner (3):
  dtc: add ability to make nodes conditional on them being referenced
  ARM: dts: imx6sl: move pingroups back into soc dtsi
  ARM: dts: imx6sl: add board file for BQ Cervantes

[PATCH 1/3] dtc: add ability to make nodes conditional on them being referenced

[Heiko Stübner]

From: Heiko Stuebner <heiko.stuebner-HCpLIkUQxWGakBO8gow8eQ@public.gmane.org>

On i.MX, which carries a lot of pin-groups of which most are unused on
individual boards, they noticed that this plethora of nodes also results
in the runtime-lookup-performance also degrading [0].

A i.MX-specific solution defining the pingroups in the board files but
using macros to reference the pingroup-data was not well received

This patch is trying to solve this issue in a more general way, by
adding the ability to mark nodes as needing to be referenced somewhere
in the tree.

To mark a node a needing to be referenced it must be prefixed with
/delete-unreferenced/. This makes dtc check the nodes reference-status
when creating the flattened tree, dropping it if unreferenced.

For example, the i.MX6SL pingroup

	/delete-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
		>;
	};

would only be included in the dtb if it got referenced somewhere
as pingroup via

	node {
		pinctrl-0 <&pinctrl_ecscpi1_1>;
	};

[PATCH 2/3] ARM: dts: imx6sl: move pingroups back into soc dtsi

[Heiko Stübner]

From: Heiko Stuebner <heiko.stuebner-HCpLIkUQxWGakBO8gow8eQ@public.gmane.org>

Using the delete-unreferenced flag, the pingroups can be kept globally but won't
be unecessarily included in dts files not using them.
