2022-07-06drm/msm: Stop using iommu_present()Dmitry Baryshkov1-2/+8
Even if some IOMMU has registered itself on the platform "bus", that doesn't necessarily mean it provides translation for the device we care about. Replace iommu_present() with a more appropriate check. On Qualcomm platforms the IOMMU can be specified either for the MDP/DPU device or for its parent MDSS device depending on the actual platform. Check both of them, since that is how both DPU and MDP5 drivers work.

2022-07-06drm/msm: Avoid unclocked GMU register access in 6xx gpu_busyDouglas Anderson6-33/+53
From testing on sc7180-trogdor devices, reading the GMU registers needs the GMU clocks to be enabled. Those clocks get turned on in a6xx_gmu_resume(). Confusingly enough, that function is called as a result of the runtime_pm of the GPU "struct device", not the GMU "struct device". Unfortunately the current a6xx_gpu_busy() grabs a reference to the GMU's "struct device". The fact that we were grabbing the wrong reference was easily seen to cause crashes that happen if we change the GPU's pm_runtime usage to not use autosuspend. It's also believed to cause some long tail GPU crashes even with autosuspend. We could look at changing it so that we do pm_runtime_get_if_in_use() on the GPU's "struct device", but then we run into a different problem. pm_runtime_get_if_in_use() will return 0 for the GPU's "struct device" the whole time when we're in the "autosuspend delay". That is, when we drop the last reference to the GPU but we're waiting a period before actually suspending then we'll think the GPU is off. One reason that's bad is that if the GPU didn't actually turn off then the cycle counter doesn't lose state and that throws off all of our calculations. Let's change the code to keep track of the suspend state of devfreq. msm_devfreq_suspend() is always called before we actually suspend the GPU and msm_devfreq_resume() after we resume it. This means we can use the suspended state to know if we're powered or not. NOTE: one might wonder when exactly our status function is called when devfreq is supposed to be disabled. The stack crawl I captured was: msm_devfreq_get_dev_status devfreq_simple_ondemand_func devfreq_update_target qos_notifier_call qos_max_notifier_call blocking_notifier_call_chain pm_qos_update_target freq_qos_apply apply_constraint __dev_pm_qos_update_request dev_pm_qos_update_request msm_devfreq_idle_work Fixes: eadf79286a4b ("drm/msm: Check for powered down HW in the devfreq callbacks") Signed-off-by: Douglas Anderson <dianders@chromium.org> Reviewed-by: Rob Clark <robdclark@gmail.com> Patchwork: https://patchwork.freedesktop.org/patch/489124/ Link: https://lore.kernel.org/r/20220610124639.v4.1.Ie846c5352bc307ee4248d7cab998ab3016b85d06@changeid Signed-off-by: Rob Clark <robdclark@chromium.org>

2022-07-04drm/msm/hdmi: drop hpd_regs usage on 8x74/8084Dmitry Baryshkov1-5/+0
The MSM HDMI driver has support for hpd_regs on 8x74/8084: supply regulators that are to be enabled for HPD to work. Currently these regulators contain the hpd_gdsc, which was replaced by the power-domains support and hpd-5v/hpd-5v-en, which are not used by the chip itself. They power up the ESD bridge. However it is a separate device which should be represented separately in the device tree. None of upstreamed devices support these properties. Thus drop support for them from the HDMI driver.

The HDMI driver has code to configure extra GPIOs, which predates pinctrl support. Nowadays all platforms should use pinctrl instead. Neither of upstreamed Qualcomm platforms uses these properties, so it's safe to drop them.

2022-07-04drm/msm/dsi: Use single function for resetVladimir Lypak1-27/+21
There is currently two function for performing reset: dsi_sw_reset and dsi_sw_reset_restore. Only difference between those is that latter one assumes that DSI controller is enabled. In contrary former one assumes that controller is disabled and executed during power-on. However this assumtion is not true mobile devices which have boot splash set up by boot-loader. This patch removes dsi_sw_reset_restore and makes dsi_sw_reset disable DSI controller during reset sequence if it's enabled.
