2022-02-24drm/tegra: Use dev_err_probe()Dmitry Osipenko1-25/+9
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.

The HDMI on Tegra belongs to the core power domain and we're going to enable GENPD support for the core domain. Now HDMI driver must use OPP API for driving the controller's clock rate because OPP API takes care of reconfiguring the domain's performance state based on HDMI clock rate.

2020-01-10drm/tegra: Do not implement runtime PMThierry Reding1-50/+66
The Tegra DRM driver heavily relies on the implementations for runtime suspend/resume to be called at specific times. Unfortunately, there are some cases where that doesn't work. One example is if the user disables runtime PM for a given subdevice. Another example is that the PM core acquires a reference to runtime PM during system sleep, effectively preventing devices from going into low power modes. This is intentional to avoid nasty race conditions, but it also causes system sleep to not function properly on all Tegra systems. Fix this by not implementing runtime PM at all. Instead, a minimal, reference-counted suspend/resume infrastructure is added to the host1x bus. This has the benefit that it can be used regardless of the system power state (or any transitions we might be in), or whether or not the user allows runtime PM. Atomic modesetting guarantees that these functions will end up being called at the right point in time, so the pitfalls for the more generic runtime PM do not apply here.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter1-1/+1
Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

The audio setting implementation was limited to a few specific pixel clocks.

2017-07-14drm: handle HDMI 2.0 VICs in AVI info-framesShashank Sharma1-1/+1
HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64). For any other mode, the VIC filed in AVI infoframes should be 0. HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is extended to (VIC 1-107). This patch adds a bool input variable, which indicates if the connected sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a HDMI 2.0 VIC to a HDMI 1.4 sink. This patch touches all drm drivers, who are callers of this function drm_hdmi_avi_infoframe_from_display_mode but to make sure there is no change in current behavior, is_hdmi2 is kept as false. In case of I915 driver, this patch: - checks if the connected display is HDMI 2.0. - HDMI infoframes carry one of this two type of information: - VIC for 4K modes for HDMI 1.4 sinks - S3D information for S3D modes As CEA-861-F has already defined VICs for 4K videomodes, this patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks, until the mode is 3D.

git://anongit.freedesktop.org/tegra/linux into drm-next drm/tegra: Changes for v4.8-rc1 This set of changes contains a bunch of cleanups to the host1x driver as well as the addition of a pin controller for DPAUX, which is required by boards to configure the DPAUX pads in AUX mode (for DisplayPort) or I2C mode (for HDMI and DDC). Included is also a bit of rework of the SOR driver in preparation to add DisplayPort support as well as some refactoring and cleanup. Finally, all output drivers are converted to runtime PM, which greatly simplifies the handling of clocks and resets. * tag 'drm/tegra/for-4.8-rc1' of git://anongit.freedesktop.org/tegra/linux: (35 commits) drm/tegra: sor: Reject HDMI 2.0 modes drm/tegra: sor: Prepare for generic PM domain support drm/tegra: dsi: Prepare for generic PM domain support drm/tegra: sor: Make XBAR configurable per SoC drm/tegra: sor: Use sor1_src clock to set parent for HDMI dt-bindings: display: tegra: Add source clock for SOR drm/tegra: sor: Implement sor1_brick clock drm/tegra: sor: Implement runtime PM drm/tegra: hdmi: Implement runtime PM drm/tegra: dsi: Implement runtime PM drm/tegra: dc: Implement runtime PM drm/tegra: hdmi: Enable audio over HDMI drm/tegra: sor: Do not support deep color modes drm/tegra: sor: Extract tegra_sor_mode_set() drm/tegra: sor: Split out tegra_sor_apply_config() drm/tegra: sor: Rename tegra_sor_calc_config() drm/tegra: sor: Factor out tegra_sor_set_parent_clock() drm/tegra: dpaux: Add pinctrl support dt-bindings: Add bindings for Tegra DPAUX pinctrl driver drm/tegra: Prepare DPAUX for supporting generic PM domains ...
2016-07-04drm/tegra: hdmi: Implement runtime PMThierry Reding1-47/+88
Use runtime PM to clock-(un)gate and (de)assert reset to the HDMI controller. This ties in nicely with atomic DPMS in that a runtime PM reference is taken before a pipe is enabled and dropped after it has been shut down. Signed-off-by: Thierry Reding <treding@nvidia.com>
2016-07-04drm/tegra: hdmi: Enable audio over HDMIThierry Reding1-104/+340
In order to use the HDA codec to forward audio data to the HDMI codec it needs the ELD that is parsed from the monitor's EDID. Also implement an interoperability mechanism between the HDA controller and the HDMI codec. This uses vendor-defined scratch registers to pass data from the HDMI codec driver to the HDMI driver (that implements the receiving end of the HDMI codec). A custom format is used to pass audio sample rate and channel count to the HDMI driver. Signed-off-by: Thierry Reding <treding@nvidia.com>

2015-08-13drm/tegra: hdmi: Restore DPMSThierry Reding1-45/+29
In order to restore DPMS with atomic mode-setting, move all code from the ->mode_set() callback into ->enable(). At the same time, rename the ->prepare() callback to ->disable() to use the names preferred by atomic mode-setting. This simplifies the calling sequence and will allow DPMS code to use runtime PM in subsequent patches. Signed-off-by: Thierry Reding <treding@nvidia.com>

2015-02-19drm/tegra: hdmi: Explicitly set clock rateThierry Reding1-0/+8
Recent changes in the clock framework have caused a behavioural change in that clocks that have not had their rate set explicitly will now be reset to their initial rate (or 0) when the clock is released. This is triggered in the deferred probing path, resulting in the clock running at a wrong frequency after the successful probe. This can be easily fixed by setting the rate explicitly rather than by relying on the implicit rate inherited by the parent.

2015-01-27drm/tegra: dc: Unify enabling the display controllerThierry Reding1-10/+0
Previously output drivers would enable continuous display mode and power up the display controller at various points during the initialization. This is suboptimal because it accesses display controller registers in output drivers and duplicates a bit of code. Move this code into the display controller driver and enable the display controller as the final step of the ->mode_set_nofb() implementation. Signed-off-by: Thierry Reding <treding@nvidia.com>
2015-01-27drm/tegra: Remove unused ->mode_fixup() callbacksThierry Reding1-27/+0

2015-01-27drm/tegra: hdmi: Implement ->atomic_check()Thierry Reding1-0/+22
The implementation of the ->atomic_check() callback precomputes all parameters to check if the given configuration can be applied. If so the precomputed values are stored in the atomic state object for the encoder and applied during modeset. In that way the modeset no longer needs to perform any checking but simply program values into registers. Signed-off-by: Thierry Reding <treding@nvidia.com>
2015-01-27drm/tegra: Atomic conversion, phase 2Thierry Reding1-0/+2

2015-01-27drm/tegra: Atomic conversion, phase 1Thierry Reding1-0/+2
Implement initial atomic state handling. Hook up the CRTCs, planes' and connectors' ->atomic_destroy_state() callback to ensure that the atomic state objects don't leak. Furthermore the CRTC now implements the ->mode_set_nofb() callback that is used by new helpers to implement ->mode_set() and ->mode_set_base(). These new helpers also make use of the new plane helper functions which the driver now provides. Signed-off-by: Thierry Reding <treding@nvidia.com>
