* tegra: camera: rtcpu: reboot after failed testsPekka Pessi2018-02-22
| | | | | | | | | | | | | | | | | | | | Flush the RTCPU tracer and print out the RTCPU log entries after a test run. Reboot rtcpu after a failed test run. An unsuccessful test test may leave RTCPU in a bad state with references to the soon-to-be-unmapped memory, which may crash the whole device.

* platform: tegra: rtcpu: refactor pm and probingPekka Pessi2017-05-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Firmware provides now the PM features for suspend and resume. Firmware activates the WDT after boot synchronization and deactivates it when suspended. The boot synchronization and the IVC service synchronization can be redone at any time. The driver requires firmware version SM4 because the earlier firmwares can not resume gracefully from the suspended state. Reorder initialization in order to avoid accessing hardware before it is fully powered. Note that powering HW with the APE power domain during the probe() may happen when pm_runtime_get_sync() is called and both resume and runtime_resume may get invoked in the process. Add checks to avoid any premature resumes. Assert resets in the reverse order they are deasserted. Enable clocks before touching any resources, including getting interrupt resources. Fix the unbalanced early_resume/late_suspend. The power domain does not track the last busy from the children of the rtcpu device. Mark the rtcpu device last busy always when the ivc channel devices are used, too. The IVC channels are now created only after the initial boot sync and version exchange with the firmware. When the IVC sync is done the RTCPU and device are both up and ready. Do not expose boot and halt methods. Instead provide the reboot method, which will only proceed when the rtcpu device is in the active runtime state. Follow suspend procedure from APE TRM. Wait for APE WFI using an interrupt. Wait for APE L2 cache to idle. Allocate an interrupt for APE WFI. Move all register handling to core-specific functions (tegra_ape_cam*(), tegra_sce_cam*()). Do not use the ahub clock. Power off RTCPU and remove the tracer during remove. Tracer can be disabled or enabled in the device tree. Treat it as an optional feature.

* drivers: tegra: rtcpu: dynamic IOVM configurationMika Liljeberg2017-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | Dynamically allocate shared memory buffers for IVC channels and tracing. The IOVM areas are communicated to RTCPU with a new CH_SETUP mailbox command. The beginning of each memory area contains a descriptor list in tag-length-value format, which describes the contents of the IO memory area. The RTCPU firmware will parse the descriptors and configure IVC services and tracing accordingly. Success or failure is communicated through the CH_SETUP response.
