QTI 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: should be "qti,tzlog"
 - interrupts: must contain interrupt used by TZ when XPU or SMMU faults are
		found
 - qti,tz-diag-buf-size: contains the TZ diag buffer size
 - qti,tz-ring-off: contains the TZ diag buffer ring offset
 - qti,tz-log-pos-info-off: contains the TZ diag buffer log position info offset

Optional properties:
 - qti,tz_kpss: should be set in case of IPQ806x platform
 - qti,hvc-enabled: defines whether TZ supports Hypervisor mode or not
 - qti,get-smmu-state: when set, will be able to get the SMMU state
 - qti,tzbsp-diag-buf-start: contains the TZ diag buffer start (as defined in
		QSEE). When specified, NS world will directly read from the
		region and dump it unlike reading the buffer via SCM interface

Example:

IPQ806x:
	qti,tzlog {
		compatible = "qti,tzlog";
		qti,tz-diag-buf-size = <0x1000>;
		qti,tz-ring-off = <7>;
		qti,tz-log-pos-info-off = <0>;
		qti,tz_kpss;
	};

IPQ40xx:
	qti,tzlog {
		compatible = "qti,tzlog";
		qti,tz-diag-buf-size = <0x1000>;
		qti,tz-ring-off = <7>;
		qti,tz-log-pos-info-off = <522>;
	};

IPQ807x:
	qti,tzlog {
		compatible = "qti,tzlog";
		interrupts = <GIC_SPI 244 IRQ_TYPE_EDGE_RISING>;
		qti,tz-diag-buf-size = <0x2000>;
		qti,tz-ring-off = <7>;
		qti,tz-log-pos-info-off = <579>;
		qti,hvc-enabled;
		qti,get-smmu-state;
	};

		qti,tz-diag-buf-size = <0x3000>;
		qti,tz-ring-off = <7>;
		qti,tz-log-pos-info-off = <810>;

		qti,tzbsp-diag-buf-start = <0x4a7df000>;
		qti,tz-diag-buf-size = <0x3000>;
		qti,tz-ring-off = <7>;
