Subject: [PATCH RFC v3 4/9] dt-bindings: arm: qcom: Update Devicetree
identifiers
From: Amrit Anand <quic_amrianan@...cinc.com>
Update existing documentation for qcom,msm-id (interchangeably:
qcom,soc-id) and qcom,board-id. Add support for qcom,pmic-id, qcom,oem-id
to support multi-DTB selection on Qualcomm's boards.
"qcom,soc-id", "qcom,board-id" and "qcom,pmic-id" are tuples of two 32-bit
values. The "qcom,oem-id" is a tuple of one 32-bit value.
Introduce macros to help generate SOC, board, PMIC and OEM identifiers.
QCOM_SOC_ID and QCOM_SOC_REVISION can be used to generate qcom,msm-id.
QCOM_BOARD_ID and QCOM_BOARD_SUBTYPE can be used to generate qcom,board-id.
QCOM_PMIC_SID and QCOM_PMIC_MODEL can be used to generate qcom,pmic-id.
QCOM_OEM_ID can be used to generate qcom,oem-id.
Add entries for different types of SoC, boards, DDR type, Boot device
type which are currently used by Qualcomm based bootloader.
