Qualcomm Hardware Mutex Block: The hardware block provides mutexes utilized between different processors on the SoC as part of the communication protocol used by these processors. - compatible: Usage: required Value type: <string> Definition: must be one of: "qcom,sfpb-mutex", "qcom,tcsr-mutex" - syscon: Usage: required Value type: <prop-encoded-array> Definition: one cell containing: syscon phandle offset of the hwmutex block within the syscon stride of the hwmutex registers - #hwlock-cells: Usage: required Value type: <u32> Definition: must be 1, the specified cell represent the lock id (hwlock standard property, see hwlock.txt) Example: tcsr_mutex_block: syscon@fd484000 { compatible = "syscon"; reg = <0xfd484000 0x2000>; }; hwlock@fd484000 { compatible = "qcom,tcsr-mutex"; syscon = <&tcsr_mutex_block 0 0x80>; #hwlock-cells = <1>; }; |
