There are however still +problems with that consensus: +1. It was reached 7 years ago but it turned out its implementation did + not reach all possible products. + +2. Initially additional tool (dtbTool) was needed for parsing these + fields to create a QCDT image consisting of multiple DTBs, later the + bootloaders were improved and they use these qcom,msm-id and + qcom,board-id properties directly. + +3. Extracting relevant information from the board compatible requires + this additional tool (dtbTool), which makes the build process more + complicated and not easily reproducible (DTBs are modified after the + kernel build). + +4. Some versions of Qualcomm bootloaders expect these properties even + when booting with a single DTB. The community is stuck with these + bootloaders thus they require properties in the DTBs. + +Since several upstreamed Qualcomm SoC-based boards require these +properties to properly boot and the properties are reportedly used by +bootloaders, document them along with the bindings header with constants +used by: bootloader, some DTS and socinfo driver. + +Link: https://lore.kernel.org/r/a3c932d1-a102-ce18-deea-18cbbd05ecab@linaro.org/ +Co-developed-by: Kumar Gala <galak@codeaurora.org> +Signed-off-by: Kumar Gala <galak@codeaurora.org> +Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> +Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> +Reviewed-by: Rob Herring <robh@kernel.org> +Signed-off-by: Bjorn Andersson <andersson@kernel.org> +Link: https://lore.kernel.org/r/20220830065744.161163-2-krzysztof.kozlowski@linaro.org +--- + include/dt-bindings/arm/qcom,ids.h | 155 +++++++++++++++++++++++++++++ + 1 file changed, 155 insertions(+) + create mode 100644 include/dt-bindings/arm/qcom,ids.h + +--- /dev/null ++++ b/include/dt-bindings/arm/qcom,ids.h +@@ -0,0 +1,155 @@ ++/* SPDX-License-Identifier: GPL-2.0-only OR BSD-2-Clause */ ++/* ++ * Copyright (c) 2015, The Linux Foundation.
