4 Subject: [PATCH] dt-bindings: arm: qcom: document qcom,msm-id and
7 The top level qcom,msm-id and qcom,board-id properties are utilized by
8 bootloaders on Qualcomm MSM platforms to determine which device tree
9 should be used and passed to the kernel.
11 The commit b32e592d3c28 ("devicetree: bindings: Document qcom board
12 compatible format") from 2015 was a consensus during discussion about
13 upstreaming qcom,msm-id and qcom,board-id fields. There are however still
14 problems with that consensus:
15 1. It was reached 7 years ago but it turned out its implementation did
16 not reach all possible products.
18 2. Initially additional tool (dtbTool) was needed for parsing these
19 fields to create a QCDT image consisting of multiple DTBs, later the
20 bootloaders were improved and they use these qcom,msm-id and
21 qcom,board-id properties directly.
23 3. Extracting relevant information from the board compatible requires
24 this additional tool (dtbTool), which makes the build process more
25 complicated and not easily reproducible (DTBs are modified after the
28 4. Some versions of Qualcomm bootloaders expect these properties even
29 when booting with a single DTB. The community is stuck with these
30 bootloaders thus they require properties in the DTBs.
32 Since several upstreamed Qualcomm SoC-based boards require these
33 properties to properly boot and the properties are reportedly used by
34 bootloaders, document them along with the bindings header with constants
35 used by: bootloader, some DTS and socinfo driver.
