| 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 |
| |
| 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; |
| }; |
| |
| IPQ60xx: |
| qti,tzlog { |
| compatible = "qti,tzlog"; |
| interrupts = <GIC_SPI 244 IRQ_TYPE_EDGE_RISING>; |
| qti,tz-diag-buf-size = <0x3000>; |
| qti,tz-ring-off = <7>; |
| qti,tz-log-pos-info-off = <810>; |
| qti,hvc-enabled; |
| qti,get-smmu-state; |
| }; |
