1Qualcomm Hardware Mutex Block:
2
3The hardware block provides mutexes utilized between different processors on
4the SoC as part of the communication protocol used by these processors.
5
6- compatible:
7	Usage: required
8	Value type: <string>
9	Definition: must be one of:
10		    "qcom,sfpb-mutex",
11		    "qcom,tcsr-mutex"
12
13- syscon:
14	Usage: required
15	Value type: <prop-encoded-array>
16	Definition: one cell containing:
17		    syscon phandle
18		    offset of the hwmutex block within the syscon
19		    stride of the hwmutex registers
20
21- #hwlock-cells:
22	Usage: required
23	Value type: <u32>
24	Definition: must be 1, the specified cell represent the lock id
25		    (hwlock standard property, see hwlock.txt)
26
27Example:
28
29	tcsr_mutex_block: syscon@fd484000 {
30		compatible = "syscon";
31		reg = <0xfd484000 0x2000>;
32	};
33
34	hwlock@fd484000 {
35		compatible = "qcom,tcsr-mutex";
36		syscon = <&tcsr_mutex_block 0 0x80>;
37
38		#hwlock-cells = <1>;
39	};
