Board/SoC top-level compatible bindings should be constrained to the root node. Add the missing constraints that the node name must be "/".

|
Some qcom based bootloaders identify the dtb blob based on a set of
|
|
device properties like SoC and platform and revisions of those components.
|
|
To support this scheme, we encode this information into the board compatible
|
|
string.
|
|
|
|
Each board must specify a top-level board compatible string with the following
|
|
format:
|
|
|
|
compatible = "qcom,<SoC>[-<soc_version>][-<foundry_id>]-<board>[/<subtype>][-<board_version>]"
|
|
|
|
The 'SoC' and 'board' elements are required. All other elements are optional.
|
|
|
|
The 'SoC' element must be one of the following strings:
|
|
|
|
apq8016
|
|
apq8074
|
|
apq8084
|
|
apq8096
|
|
ipq6018
|
|
ipq8074
|
|
mdm9615
|
|
msm8916
|
|
msm8974
|
|
msm8992
|
|
msm8994
|
|
msm8996
|
|
sc7180
|
|
sdm630
|
|
sdm660
|
|
sdm845
|
|
|
|
The 'board' element must be one of the following strings:
|
|
|
|
cdp
|
|
cp01-c1
|
|
dragonboard
|
|
hk01
|
|
idp
|
|
liquid
|
|
mtp
|
|
qrd
|
|
sbc
|
|
|
|
The 'soc_version' and 'board_version' elements take the form of v<Major>.<Minor>
|
|
where the minor number may be omitted when it's zero, i.e. v1.0 is the same
|
|
as v1. If all versions of the 'board_version' elements match, then a
|
|
wildcard '*' should be used, e.g. 'v*'.
|
|
|
|
The 'foundry_id' and 'subtype' elements are one or more digits from 0 to 9.
|
|
|
|
Examples:
|
|
|
|
"qcom,msm8916-v1-cdp-pm8916-v2.1"
|
|
|
|
A CDP board with an msm8916 SoC, version 1 paired with a pm8916 PMIC of version
|
|
2.1.
|
|
|
|
"qcom,apq8074-v2.0-2-dragonboard/1-v0.1"
|
|
|
|
A dragonboard board v0.1 of subtype 1 with an apq8074 SoC version 2, made in
|
|
foundry 2.
