The origin Idea behind it is to prevent code duplication. For now there is only the avari baseboard which is upstreamed.
But for example, the Bvari [1] baseboard is upcoming and then we'll have code duplication for the csi node and their pincontrols.
Also I wanted a clean split between the processor module description (which is the emCON-MX6) and the baseboard (Avari),
to make it cleaner to integrate the module code with custom products (for example from our customers) without changing the File-layout over and over.

I wanted to have a generic entry point to address the board-id on all CPU-modules with their different SoC's resulting in different devicetree paths.
Also as it now has the generic "gpio@3a" name, there would be no other way in differencing the board Identifying GPIO-expander from an additionally
attached one (except platform code etc.)
With the alias every code could look up the information required over the alias path with the same piece of code.

>From your point of view I agree, but our customers using the emCON module do not have
the schematics as I do, so they would have to create custom groups for every application the emCON-MX6[2] module is used for.
With those pinctrls defined, the modules dtsi much more generic to use for different baseboards and applications, IF they're used as specified on the connector.
Also the pinctrl_names are deferred from the Names on the Hardware Interface. For example &pinctrl_emcon_gpio5 is for the signal "GPIO_5" on the emCON connector.
Some of them are not even connected on the baseboard so they are in the Hog group, to force default settings for them.

About pinctrl_nor_flash I fully agree, that's a mistake.
pinctrl_usdhc2 is not connected on the avari, and therefore not enabled.
As told before it is added to the Hog group to force the default pinmuxing without enabling the hardware itself.

I used the Kernel documentation as reference:
Documentation/devicetree/bindings/display/panel/simple-panel.txt-Example:
Documentation/devicetree/bindings/display/panel/simple-panel.txt-
Documentation/devicetree/bindings/display/panel/simple-panel.txt: panel: panel {
Documentation/devicetree/bindings/display/panel/simple-panel.txt- compatible = "cptt,claa101wb01";
Documentation/devicetree/bindings/display/panel/simple-panel.txt- ddc-i2c-bus = <&panelddc>;
Documentation/devicetree/bindings/display/panel/simple-panel.txt-
Same for a lot entries there...
sharp,ls037v7dw01.txt-lcd0: display {
samsung,s6e3ha2.txt- panel@0 {
sharp,lq101r1sx01.txt- panel: panel@0 {
etc. etc.

Really? Why should it be a generic name for "gpio" and "pmic" but not a generic name for an "rtc" chip?
