* TZLOG (Trust Zone Log)
The tz_log driver is a platform device driver that exposes a debugfs
interface for accessing and displaying diagnostic information
related to secure code (Trustzone/QSEE).
Required properties:
- compatible : Should be "qcom,tz-log"
- reg : Offset and size of the register set for the device
Optional properties:
- qcom,hyplog-enabled : (boolean) indicates if driver supports HYP logger service.
- hyplog-address-offset : Register offset to get the HYP log base address.
- hyplog-size-offset : Register offset to get the HYP log size parameter.
Example:
qcom,tz-log@146bf720 {
compatible = "qcom,tz-log";
reg = <0x146bf720, 0x3000>;
qcom,hyplog-enabled;
hyplog-address-offset = 0x410;
hyplog-size-offset = 0x414;
};
