drm/msm/hdmi_pll_8960: convert from round_rate() to determine_rate()

2025-08-28T22:51:46Z

The round_rate() clk ops is deprecated, so migrate this driver from round_rate() to determine_rate() using the Coccinelle semantic patch on the cover letter of this series.

drm/bridge: Pass down connector to drm bridge detect hook

2025-07-14T15:23:18Z

In some application scenarios, we hope to get the corresponding connector when the bridge's detect hook is invoked. In most cases, we can get the connector by drm_atomic_get_connector_for_encoder if the encoder attached to the bridge is enabled, however there will still be some scenarios where the detect hook of the bridge is called but the corresponding encoder has not been enabled yet. For instance, this occurs when the device is hot plug in for the first time. Since the call to bridge's detect is initiated by the connector, passing down the corresponding connector directly will make things simpler.

drm/msm: move KMS driver data to msm_kms

2025-07-05T14:13:35Z

Data for HDMI, DSI and DP blocks only makes sense for the KMS parts of the driver. Move corresponding data pointers from struct msm_drm_private to struct msm_kms.

drm/msm/hdmi: wire in hpd_enable/hpd_disable bridge ops

2025-05-12T16:18:48Z

The HDMI driver already has msm_hdmi_hpd_enable() and msm_hdmi_hpd_disable() functions. Wire them into the msm_hdmi_bridge_funcs, so that HPD can be enabled and disabled dynamically rather than always having HPD events generation enabled.

drm/msm/hdmi: ensure that HDMI is up if HPD is requested

2025-05-12T16:18:48Z

The HDMI block needs to be enabled to properly generate HPD events. Make sure it is not turned off in the disable paths if HPD delivery is enabled.
