2023-12-04Revert "drm: Introduce pixel_source DRM plane property"Dmitry Baryshkov
This reverts commit e50e5fed41c7eed2db4119645bf3480ec43fec11. Although the Solid Fill planes patchset got all reviews and acknowledgements, it doesn't fulfill requirements for the new uABI. It has neither corresponding open-source userspace implementation nor the IGT tests coverage. Reverting this patchset until userspace obligations are fulfilled.

The i2c_master_send/recv() functions return negative error codes or the number of bytes that were able to be sent/received. This code has two problems. 1) Instead of checking if all the bytes were sent or received, it checks that at least one byte was sent or received. 2) If there was a partial send/receive then we should return a negative error code but this code returns success.

2023-12-03drm: remove drm_bridge_hpd_disable() from drm_bridge_connector_destroy()Abhinav Kumar
drm_bridge_hpd_enable()/drm_bridge_hpd_disable() callbacks call into the respective driver's hpd_enable()/hpd_disable() ops. These ops control the HPD enable/disable logic which in some cases like MSM can be a dedicate hardware block to control the HPD. During probe_defer cases, a connector can be initialized and then later destroyed till the probe is retried. During connector destroy in these cases, the hpd_disable() callback gets called without a corresponding hpd_enable() leading to an unbalanced state potentially causing even a crash. This can be avoided by the respective drivers maintaining their own state logic to ensure that a hpd_disable() without a corresponding hpd_enable() just returns without doing anything. However, to have a generic fix it would be better to avoid the hpd_disable() callback from the connector destroy path and let the hpd_enable() / hpd_disable() balance be maintained by the corresponding drm_bridge_connector_enable_hpd() / drm_bridge_connector_disable_hpd() APIs which should get called by drm_kms_helper_disable_hpd(). changes in v2: - minor change in commit text (Dmitry) Signed-off-by: Abhinav Kumar <quic_abhinavk@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/20230919174813.26958-1-quic_abhinavk@quicinc.com

2023-12-03drm/msm/dp: incorporate pm_runtime framework into DP driverKuogee Hsieh
Currently DP driver is executed independent of PM runtime framework. This leads msm eDP panel can not being detected by edp_panel driver during generic_edp_panel_probe() due to AUX DPCD read failed at edp panel driver. Incorporate PM runtime framework into DP driver so that host controller's power and clocks are enable/disable through PM runtime mechanism. Once PM runtime framework is incorporated into DP driver, waking up device from power up path is not necessary. Hence remove it. After incorporating pm_runtime framework into eDP/DP driver, dp_pm_suspend() to handle power off both DP phy and controller during suspend and dp_pm_resume() to handle power on both DP phy and controller during resume are not necessary. Therefore both dp_pm_suspend() and dp_pm_resume() are dropped and replace with dp_pm_runtime_suspend() and dp_pm_runtime_resume() respectively. Changes in v9: -- silent compiler warning message at dp_power_init() and dp_power_deinit() with W1 flag Changes in v7: -- add comments to dp_pm_runtime_resume() -- add comments to dp_bridge_hpd_enable() -- delete dp->hpd_state = ST_DISCONNECTED from dp_bridge_hpd_notify() Changes in v6: -- delete dp_power_client_deinit(dp->power); -- remove if (!dp->dp_display.is_edp) condition checkout at plug_handle() -- remove if (!dp->dp_display.is_edp) condition checkout at unplug_handle() -- add IRQF_NO_AUTOEN to devm_request_irq() -- add enable_irq() and disable_irq() to pm_runtime_resume()/suspend() -- del dp->hpd_state = ST_DISCONNECTED from dp_bridge_hpd_disable() Changes in v5: -- remove pm_runtime_put_autosuspend feature, use pm_runtime_put_sync() -- squash add pm_runtime_force_suspend()/resume() patch into this patch Changes in v4: -- reworded commit text to explain why pm_framework is required for edp panel -- reworded commit text to explain autosuspend is choiced -- delete EV_POWER_PM_GET and PM_EV_POWER_PUT from changes #3 -- delete dp_display_pm_get() and dp_display_pm_Put() from changes #3 -- return value from pm_runtime_resume_and_get() directly -- check return value of devm_pm_runtime_enable() -- delete pm_runtime_xxx from dp_display_remove() -- drop dp_display_host_init() from EV_HPD_INIT_SETUP -- drop both dp_pm_prepare() and dp_pm_compete() from this change -- delete ST_SUSPENDED state -- rewording commit text to add more details regrading the purpose of this change Changes in v3: -- incorporate removing pm_runtime_xx() from dp_pwer.c to this patch -- use pm_runtime_resume_and_get() instead of pm_runtime_get() -- error checking pm_runtime_resume_and_get() return value -- add EV_POWER_PM_GET and PM_EV_POWER_PUT to handle HPD_GPIO case -- replace dp_pm_suspend() with pm_runtime_force_suspend() -- replace dp_pm_resume() with pm_runtime_force_resume() Signed-off-by: Kuogee Hsieh <quic_khsieh@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Patchwork: https://patchwork.freedesktop.org/patch/570073/ Link: https://lore.kernel.org/r/1701472789-25951-6-git-send-email-quic_khsieh@quicinc.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
