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>;
|
|
};
