Subject: [PATCH 5/7] devicetree: bindings: Document qcom,msm-id and
|
|
qcom,board-id
|
|
|
|
The top level qcom,msm-id and qcom,board-id are utilized by bootloaders
|
|
on Qualcomm MSM platforms to determine which device tree should be
|
|
utilized and passed to the kernel.

+* MSM-ID
|
|
+
|
|
+The qcom,msm-id entry specifies the MSM chipset and hardware revision. It can
|
|
+optionally be an array of these to indicate multiple hardware that use the same
|
|
+device tree. It is expected that the bootloader will use this information at
|
|
+boot-up to decide which device tree to use when given multiple device trees,
|
|
+some of which may not be compatible with the actual hardware. It is the
|
|
+bootloader's responsibility to pass the correct device tree to the kernel.
|
|

+PROPERTIES

|
|
+- qcom,msm-id:
|
|
+ Usage: required
|
|
+ Value type: <prop-encoded-array> (<chipset_id, rev_id> [, <c2, r2> ..])
|
|
+ Definition:
|
|
+ The "chipset_id" consists of three fields as below:
|
|
+
|
|
+ bits 0-15 = The unique MSM chipset id.
|
|
+ bits 16-31 = Reserved. Should be 0
|
|
+
|
|
+ chipset_id is an exact match value
|
|
+
|
|
+ The "rev_id" is a chipset specific 32-bit id that represents
|
|
+ the version of the chipset.
|
|
+
|
|
+ The rev_id is a best match id. The bootloader will look for
|
|
+ the closest possible patch.
|
|
+
|
|
+* BOARD-ID
|
|
+
|
|
+The qcom,board-id entry specifies the board type and revision information. It
|
|
+can optionally be an array of these to indicate multiple boards that use the
|
|
+same device tree. It is expected that the bootloader will use this information
|
|
+at boot-up to decide which device tree to use when given multiple device trees,
|
|
+some of which may not be compatible with the actual hardware. It is the
|
|
+bootloader's responsibility to pass the correct device tree to the kernel.

+- qcom,board-id:
|
|
+ Usage: required
|
|
+ Value type: <prop-encoded-array> (<board_id, subtype_id> [, <b2, s2> ..])
|
|
+ Definition:
|
|
+ The "board_id" consists of three fields as below:
|
|
+
|
|
+ bits 31-24 = Unusued.
|
|
+ bits 23-16 = Platform Version Major
|
|
+ bits 15-8 = Platfrom Version Minor
|
|
+ bits 7-0 = Platform Type
|
|
+
|
|
+ Platform Type field is an exact match value. The Platform
|
|
+ Major/Minor field is a best match. The bootloader will look
|
|
+ for the closest possible match.
|
|
+
|
|
+ The "subtype_id" is unique to a Platform Type/Chipset ID. For
|
|
+ a given Platform Type, there will typically only be a single
|
|
+ board and the subtype_id will be 0. However in some cases board
|
|
+ variants may need to be distinquished by different subtype_id
|
|
+ values.
|
|
+
|
|
+ subtype_id is an exact match value.
|
|
+
|
|
+EXAMPLE:
|
|
+ qcom,board-id = <15 2>;
|
|
+ qcom,msm-id = <0x1007e 0>;
