1QCOM device tree bindings 2------------------------- 3 4Some qcom based bootloaders identify the dtb blob based on a set of 5device properties like SoC and platform and revisions of those components. 6To support this scheme, we encode this information into the board compatible 7string. 8 9Each board must specify a top-level board compatible string with the following 10format: 11 12 compatible = "qcom,<SoC>[-<soc_version>][-<foundry_id>]-<board>[/<subtype>][-<board_version>]" 13 14The 'SoC' and 'board' elements are required. All other elements are optional. 15 16The 'SoC' element must be one of the following strings: 17 18 apq8016 19 apq8074 20 apq8084 21 apq8096 22 msm8916 23 msm8974 24 msm8992 25 msm8994 26 msm8996 27 mdm9615 28 ipq8074 29 sdm845 30 31The 'board' element must be one of the following strings: 32 33 cdp 34 liquid 35 dragonboard 36 mtp 37 sbc 38 hk01 39 40The 'soc_version' and 'board_version' elements take the form of v<Major>.<Minor> 41where the minor number may be omitted when it's zero, i.e. v1.0 is the same 42as v1. If all versions of the 'board_version' elements match, then a 43wildcard '*' should be used, e.g. 'v*'. 44 45The 'foundry_id' and 'subtype' elements are one or more digits from 0 to 9. 46 47Examples: 48 49 "qcom,msm8916-v1-cdp-pm8916-v2.1" 50 51A CDP board with an msm8916 SoC, version 1 paired with a pm8916 PMIC of version 522.1. 53 54 "qcom,apq8074-v2.0-2-dragonboard/1-v0.1" 55 56A dragonboard board v0.1 of subtype 1 with an apq8074 SoC version 2, made in 57foundry 2. 58
