  Usage: optional (default: 4.2V, or pre-configured value)

  Value type: <u32>; uV; range [3.24V : 5V]

- qcom,jeita-extended-temp-range:

  Usage: optional (default: false)

  Value type: boolean: <u32> or <empty>

  Description: Enable JEITA extended temperature range;  This does *not*

               adjust the maximum charge voltage or current in the extended

               temperature range.  It only allows charging when the battery

               is in the extended temperature range.  Voltage/current

               regulation must be done externally to fully comply with

               the JEITA safety guidelines if this flag is set.

Qualcomm Shared Memory Manager binding



This binding describes the Qualcomm Shared Memory Manager, used to share data

between various subsystems and OSes in Qualcomm platforms.



- compatible:

	Usage: required

	Value type: <stringlist>

	Definition: must be:

		    "qcom,smem"

	Value type: <prop-encoded-array>

	Definition: handle to memory reservation for main SMEM memory region.



- qcom,rpm-msg-ram:

	Usage: required

	Value type: <prop-encoded-array>

	Definition: handle to RPM message memory resource



- hwlocks:

	Usage: required

	Value type: <prop-encoded-array>

	Definition: reference to a hwspinlock used to protect allocations from

		    the shared memory
