[PATCH v2 0/3] ARM: dts: imx6ul-kontron: Improve devicetrees

From: Frieder Schrempf <hidden>
Date: 2022-08-10 08:18:50 

From: Frieder Schrempf <redacted>

This series contains some simplifications to the devicetree file structure
and updates the model names, compatibles and devicetree file names to match
what is used officially by the Kontron marketing.

This is a somewhat breaking change (for out-of-tree devicetrees that include
the SoM files) but it reduces the complexity quite a bit, makes things easier
to read and lets people discover the devicetree matching their hardware more
easily.

The first patch also updates the bindings to match up with the changes applied
in the following patches.

This series doesn't contain any functional changes.
---
Changes in v2:
* Also rename compatibles to get rid of N6xxx notation
* Also rename devicetree files for consistency
* Squash model renaming patch into patch 2
* Move part of Makefile changes to patch 2

[PATCH v2 1/3] dt-bindings: arm: fsl: imx6ul-kontron: Update bindings

From: Frieder Schrempf <hidden>
Date: 2022-08-10 08:19:02 

From: Frieder Schrempf <redacted>

This updates the bindings in order to simplify the devicetree
structure and to add names for the boards that follow the latest
convention used by Kontron marketing.

It also gets rid of the N6xxx notation in the compatibles and
file names, as they are not really used anymore and often result
in confusion.

[PATCH v2 2/3] ARM: dts: imx6ul-kontron: Simplify devicetree structure

From: Frieder Schrempf <hidden>
Date: 2022-08-10 08:19:31 

From: Frieder Schrempf <redacted>

There is no need in differentiating between the different SoM versions
that only differ in memory size, etc. It's much cleaner to simplify
the devicetrees and let them be more generic.

If necessary the bootloader will update the devicetree dynamically
to contain the correct size of the memory.

We also get rid of the N6xxx notation in the compatibles and file
names, as they are not really used anymore and often result in
confusion.

[PATCH v2 3/3] ARM: dts: imx6ul-kontron: Add imx6ull-kontron-bl to Makefile

From: Frieder Schrempf <hidden>
Date: 2022-08-10 08:19:35 

From: Frieder Schrempf <redacted>

The imx6ull-kontron-bl.dtb wasn't build as part of the
CONFIG_SOC_IMX6UL option. Add it to the list.

Re: [PATCH v2 2/3] ARM: dts: imx6ul-kontron: Simplify devicetree structure

There is no need in differentiating between the different SoM versions
that only differ in memory size, etc. It's much cleaner to simplify
the devicetrees and let them be more generic.

If necessary the bootloader will update the devicetree dynamically
to contain the correct size of the memory.

We also get rid of the N6xxx notation in the compatibles and file
names, as they are not really used anymore and often result in
confusion.

Most of these should be renames with small amount of changes. You should
experiment with -B/-M/-C format-patch arguments so the end diff is easy
to read.

Re: [PATCH v2 1/3] dt-bindings: arm: fsl: imx6ul-kontron: Update bindings

This updates the bindings in order to simplify the devicetree
structure and to add names for the boards that follow the latest
convention used by Kontron marketing.

It also gets rid of the N6xxx notation in the compatibles and
file names, as they are not really used anymore and often result
in confusion.

This affects the ABI, so you should be sure that it is desired...
