2021-12-16drm/tegra: vic: Fix DMA API misuseRobin Murphy
Upon failure, dma_alloc_coherent() returns NULL. If that does happen, passing some uninitialised stack contents to dma_mapping_error() - which belongs to a different API in the first place - has precious little chance of detecting it. Also include the correct header, because the fragile transitive inclusion currently providing it is going to break soon.

2021-12-16drm/tegra: dc: rgb: Allow changing PLLD rate on Tegra30+Dmitry Osipenko
Asus Transformer TF700T is a Tegra30 tablet device which uses RGB->DSI bridge that requires a precise clock rate in order to operate properly. Tegra30 has a dedicated PLL for each display controller, hence the PLL rate can be changed freely. Allow PLL rate changes on Tegra30+ for RGB output. Configure the clock rate before display controller is enabled since DC itself may be running off this PLL and it's not okay to change the rate of the active PLL that doesn't support dynamic frequency switching since hardware will hang.

2021-12-16drm/tegra: dc: rgb: Move PCLK shifter programming to CRTCDmitry Osipenko
Asus TF700T tablet uses TC358768 DPI->DSI bridge that sits between Tegra's DPI output and display panel input. Bridge requires to have stable PCLK output before RGB encoder is enabled because it uses PCLK by itself to clock internal logic and bridge is programmed before Tegra's encoder is enabled. Hence the PCLK clock shifter must be programmed when CRTC is enabled, otherwise clock is unstable and bridge hangs because of it. Move the shifter programming from RGB encoder into CRTC.

2021-08-10gpu: host1x: Add no-recovery modeMikko Perttunen
Add a new property for jobs to enable or disable recovery i.e. CPU increments of syncpoints to max value on job timeout. This allows for a more solid model for hanged jobs, where userspace doesn't need to guess if a syncpoint increment happened because the job completed, or because job timeout was triggered. On job timeout, we stop the channel, NOP all future jobs on the channel using the same syncpoint, mark the syncpoint as locked and resume the channel from the next job, if any. The future jobs are NOPed, since because we don't do the CPU increments, the value of the syncpoint is no longer synchronized, and any waiters would become confused if a future job incremented the syncpoint. The syncpoint is marked locked to ensure that any future jobs cannot increment the syncpoint either, until the application has recognized the situation and reallocated the syncpoint.

ssh://git.freedesktop.org/git/tegra/linux into drm-next drm/tegra: Changes for v5.14-rc1 The two major changes here are fixed YUV support as well as scaling on Tegra186 and later. This allows Tegra DRM to be used, for example, as a video sink for the kmssink gstreamer plugin. The remainder of the changes are minor fixes.

2021-06-11drm/tegra: Don't call SET_APPLICATION_ID in VIC bootMikko Perttunen
The application should be programming the application ID, not the kernel, as there can be several options to choose from, and setting the application ID multiple times can cause issues. Signed-off-by: Mikko Perttunen <mperttunen@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-06-11drm/tegra: Remove superfluous error messages around platform_get_irq()Tan Zhongjun
The platform_get_irq() prints error message telling that interrupt is missing,hence there is no need to duplicated that message in the drivers. Signed-off-by: Tan Zhongjun <tanzhongjun@yulong.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-05-31drm/tegra: hub: Implement basic scaling supportThierry Reding
Parameterize code in several places to allow scaling of windows. Note that this currently still relies on static programming of the various metering and memory pool allocation registers. This seems to work for the common cases, but may eventually need to be updated to support use-cases with multiple windows and higher bandwidth and latency requirements.
