description:
The hardware block provides mutexes utilized between different processors on
the SoC as part of the communication protocol used by these processors.
properties:
compatible:
enum:
- qcom,sfpb-mutex
- qcom,tcsr-mutex
'#hwlock-cells':

description:
Should be a triple of phandle referencing the TCSR mutex syscon, offset
of first mutex within the syscon and stride between each mutex.
