drm/tegra: Add missing clk_disable_unprepare() in tegra_dc_probe()

2022-11-25T15:14:58+00:00

Add the missing clk_disable_unprepare() before return from tegra_dc_probe() in the error handling path. Fixes: f68ba6912bd2 ("drm/tegra: dc: Link DC1 to DC0 on Tegra20") Signed-off-by: Zhang Zekun Signed-off-by: Thierry Reding

drm: Remove unnecessary include statements of drm_plane_helper.h

2022-07-26T16:42:04+00:00

Remove the include statement for drm_plane_helper.h from all the files that don't need it. Althogh the header file is almost empty, many drivers include it somewhere.

Merge tag 'drm/tegra/for-5.20-rc1' of https://gitlab.freedesktop.org/drm/tegra into drm-next

2022-07-12T06:50:05+00:00

drm/tegra: Changes for v5.20-rc1 The bulk of these changes adds support for context isolation for the various supported host1x engines, as well as support for the hardware found on the new Tegra234 SoC generation. There's also a couple of fixes and cleanups. To round things off, the device tree bindings are converted to the new json-schema format that allows DTBs to be validated.

drm/tegra: Include DMA API header where used

2022-07-08T15:01:15+00:00

Even though the IOVA API never actually needed it, iova.h is still carrying an include of dma-mapping.h, now solely for the sake of not breaking tegra-drm. Fix that properly. Signed-off-by: Robin Murphy Signed-off-by: Thierry Reding

drm: Drop drm_blend.h from drm_crtc.h

2022-06-20T20:53:55+00:00

drm_crtc.h has no need for drm_blend.h, so don't include it. Avoids useless rebuilds of the entire universe when touching drm_blend.h. Quite a few placs do currently depend on drm_blend.h without actually including it directly. All of those need to be fixed up.

drm/tegra: Support semi-planar formats on Tegra114+

2022-03-01T10:13:09+00:00

The NV12, NV21, NV16, NV61, NV24 and NV42 formats are supported by Tegra114 and later display hardware. Add the necessary programming to allow them to be used. Note that this does not work for Tegra186 and later yet because those generations have a different display architecture that doesn't support the same formats. Signed-off-by: Thierry Reding

drm/tegra: Use dev_err_probe()

2022-02-24T16:03:08+00:00

Replace dev_printk() with a generic dev_err_probe() helper which silences noisy error messages about deferred probe and makes easy to debug failing deferred probe by printing notification about the failure to KMSG in the end of kernel booting process and by adding failing device and the reason of deferred probe to devices_deferred of debugfs. This was proven to be useful in the case of eDP driver regression by immediately showing why display driver was failing when user asked for help, otherwise it would've been much more difficult to debug such problems on a third party device that doesn't have developer setup.

drm/tegra: dc: Support OPP and SoC core voltage scaling

2021-12-16T13:07:07+00:00

Add OPP and SoC core voltage scaling support to the display controller driver. This is required for enabling system-wide DVFS on pre-Tegra186 SoCs.
