Subject: [PATCH v7 0/3] dt-bindings: arm: qcom: qcom,board-id and qcom,msm-id

Hi,

Changes since v6
================
1. Rebase (new IDs).
2. qcom_board_id2 -> qcom_board_id_named (Bjorn).
3. Add Rb tags.

Changes since v5
================
1. Dual-license qcom,ids.h (Rob).
2. Minor corrections in comments.

Changes since v4
================
1. Change the qcom,board-id oneOf (oneOf at higher level) so newer dtschema is happy.

Changes since v3
================
1. Patch #1: Define all SoC IDs, based on Qualcomm socid driver (Konrad). Keep
   Dmitry Rb tag, even though it is quite a change.
2. New patch #2: use bindings in the socid driver.  The patch fails on checkpatch:
   "Macros with complex values should be enclosed in parentheses"
   but that's expected considering the macro contents.

Changes since v2
================
1. Adjust description of new fields after review (Dmitry).
2. Change name of msm8996 define (Dmitry).
3. Add Rb tags.

Changes since v1
================
1. Make the qcom,board-id and qcom,msm-id properties deprecated and limited to
   certain SoCs (Rob).
2. Extend the qcom,board-id schema to match OnePlus variant - four elements -
   and drop DTS patches splitting four into two touples (Stephan).

Description
===========
The discussion [1] brought several arguments for keeping the qcom,board-id and
qcom,msm-id properties.  Keeping means we should document them, so the DT
schema checks pass.

I revived old patch [2] with several changes and improvements.  The commit msg
hopefully collects feedback from the discussion.

Best regards,
Krzysztof
