QCA TZLOG

This binding describes tzlog used to inspect log created by TZ. This driver
also provides capability to capture SMMU and XPU faults found by TZ.

Required properties:
 - compatible: must contain one of "qca,tzlog"
				   "qca,tz64-hv-log"
				   "qca,tz64log"
					"qca,tzlog_ipq6018"
 - interrupts: must contain interrupt used by TZ when XPU or SMMU faults are
		found

Optional properties:
 - qca,tzbsp-diag-buf-size: contains the TZ diag buffer size. If not defined,
				memory of 4K will be used.
 - qca,hyp-enabled: defines whether TZ supports Hypervisor mode or not.
 - hyp-scm-cmd-id: contains the SCM command id to get the hypervisor diag log.
			If not defined, default value 0x7 will be used.

Example:

	qca,tzlog {
		compatible = "qca,tz64log";
		interrupts = <0 244 0>;
	};

	qca,tzlog {
		compatible = "qca,tz64-hv-log";
		interrupts = <0 244 0>;
	};

	qca,tzlog {
		compatible = "qca,tzlog";
	};

	tzlog: qca,tzlog {
		compatible = "qca,tzlog_ipq6018";
		interrupts = <GIC_SPI 244 IRQ_TYPE_EDGE_RISING>;
		qca,tzbsp-diag-buf-size = <0x3000>;
		qca,hyp-enabled;
		hyp-scm-cmd-id = <0xA>;
	};
