-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 {

- syscon = <&tcsr_mutex_block 0 0x80>;
