2024-06-12drm/bridge-connector: implement glue code for HDMI connectorDmitry Baryshkov3-3/+174
In order to let bridge chains implement HDMI connector infrastructure, add necessary glue code to the drm_bridge_connector. In case there is a bridge that sets DRM_BRIDGE_OP_HDMI, drm_bridge_connector will register itself as a HDMI connector and provide proxy drm_connector_hdmi_funcs implementation. Note, to simplify implementation, there can be only one bridge in a chain that sets DRM_BRIDGE_OP_HDMI. Setting more than one is considered an error. This limitation can be lifted later, if the need arises.

2024-06-12drm/bridge-connector: switch to using drmm allocationsDmitry Baryshkov1-18/+5
Turn drm_bridge_connector to using drmm_kzalloc() and drmm_connector_init() and drop the custom destroy function. The drm_connector_unregister() and fwnode_handle_put() are already handled by the drm_connector_cleanup() and so are safe to be dropped.

2024-06-12drm/connector: hdmi: allow disabling Audio InfoframeDmitry Baryshkov2-0/+37
Add drm_atomic_helper_connector_hdmi_disable_audio_infoframe(), an API to allow the driver disable sending the Audio Infoframe. This is to be used by the drivers if setup of the infoframes is not tightly coupled with the audio functionality and just disabling the audio playback doesn't stop the HDMI hardware from sending the Infoframe.

2024-06-11drm/panel: raydium-rm67191: Don't call unprepare+disable at shutdownDouglas Anderson1-9/+0
It's the responsibility of a correctly written DRM modeset driver to call drm_atomic_helper_shutdown() at shutdown time and that should be disabling / unpreparing the panel if needed. Panel drivers shouldn't be calling these functions themselves. A recent effort was made to fix as many DRM modeset drivers as possible [1] [2] [3] and most drivers are fixed now. A grep through mainline for compatible strings used by this driver indicates that it is used by IMX boards. The IMX driver appears to be correctly calling drm_atomic_helper_shutdown() so we can remove the calls.

2024-06-11drm/panel: raydium-rm67191: Stop tracking enabledDouglas Anderson1-19/+2
As talked about in commit d2aacaf07395 ("drm/panel: Check for already prepared/enabled in drm_panel"), we want to remove needless code from panel drivers that was storing and double-checking the prepared/enabled state. Even if someone was relying on the double-check before, that double-check is now in the core and not needed in individual drivers. The conversion of the rm67191 panel driver follows many of the other panel drivers but has a few differences that need to be called out. Like in commit 1e0465eb16a4 ("drm/panel: otm8009a: Don't double check prepared/enabled"), this panel also uses the "prepared" flag to prevent the backlight functions from running when the panel is powered off. This is probably not the safest thing to do but the old behavior was preserved. See the discussion in the otm8009a patch. Because of this, I've left the driver tracking "prepared" but removed its tracking of "enabled". NOTE: as part of this, transition the panel's direct calls to its disable/unprepare functions in shutdown to call through DRM panel.

The VFP, HBP, and HSA are divided between the available lanes if there is more than one lane. For certain timings and lane configurations, the HFP may not be evenly divisible. If the HFP is rounded down, it ends up being too small which can cause some monitors to not sync properly. In these instances, adjust htotal and hsync to round the HFP up, and recalculate the htotal. This allows 720P-60 to operation on an i.MX8MP with a four-lane configuration.

The P divider should be set based on the min and max values of the fin pll which may vary between different platforms. These ranges are defined per platform, but hard-coded values were used instead which resulted in a smaller range available on the i.MX8M[MNP] than what was possible. As noted by Frieder, there are descripencies between the reference manuals of the Mini, Nano and Plus, so I reached out to my NXP rep and got the following response regarding the varing notes in the documentation. "Yes it is definitely wrong, the one that is part of the NOTE in MIPI_DPHY_M_PLLPMS register table against PMS_P, PMS_M and PMS_S is not correct. I will report this to Doc team, the one customer should be take into account is the Table 13-40 DPHY PLL Parameters and the Note above."

The mode_valid implementation had a call to drm_bridge_chain_mode_fixup() which would be wrong as the mode_valid is not allowed to change anything - only to validate the mode. As the next bridge is often/always a connector the call had no effect anyway. So drop it. From the git history I could see this call was included in the original version of the driver so there was no help there to find out why it was added in the first place.

2024-06-10drm/sun4i: Fix layer zpos change/atomic modesettingOndrej Jirman4-143/+71
Identical configurations of planes can lead to different (and wrong) layer -> pipe routing at HW level, depending on the order of atomic plane changes. For example: - Layer 1 is configured to zpos 0 and thus uses pipe 0. No other layer is enabled. This is a typical situation at boot. - When a compositor takes over and layer 3 is enabled, sun8i_ui_layer_enable() will get called with old_zpos=0 zpos=1, which will lead to incorrect disabling of pipe 0 and enabling of pipe 1. What happens is that sun8i_ui_layer_enable() function may disable blender pipes even if it is no longer assigned to its layer. To correct this, move the routing setup out of individual plane's atomic_update into crtc's atomic_update, where it can be calculated and updated all at once. Remove the atomic_disable callback because it is no longer needed.
