drm/msm/dsi: Print dual-DSI-adjusted pclk instead of original mode pclk

2024-06-12T09:39:28+00:00

[ Upstream commit f12e0e12524a34bf145f7b80122e653ffe3d130a ] When dual-DSI (bonded DSI) was added in commit ed9976a09b48 ("drm/msm/dsi: adjust dsi timing for dual dsi mode") some DBG() prints were not updated, leading to print the original mode->clock rather than the adjusted (typically the mode clock divided by two, though more recently also adjusted for DSC compression) msm_host->pixel_clk_rate which is passed to clk_set_rate() just below. Fix that by printing the actual pixel_clk_rate that is being set.

drm/msm/dsi: stop calling set_split_display

2024-02-11T20:38:06+00:00

Since the commit 8b03ad30e314 ("drm/msm/dsi: Use one connector for dual DSI mode"), the second DSI host in the bonded pair will not be associated with the encoder and will not get the bridges, thus making condition in msm_dsi_manager_set_split_display() always false. Technically that change broke bonded DSI support in the MDP5 driver. But since nobody complained in the last 5.5 years, it seems that nobody cares enough. Drop the msm_dsi_manager_set_split_display() completely and stop calling the set_split_display() KMS callback. Also remove the msm_dsi::external_bridge field which was only used by the mentioned function.

drm/msm/dsi: drop msm_dsi_device_connected() function

2024-02-11T20:38:06+00:00

Since the commit 8f59ee9a570c ("drm/msm/dsi: Adjust probe order") the DSI hosts are not bound through the component framework if the DSI driver wasn't attached to the DSI device connected to this host. Afterwards, if there is no bridge (including the panel bridge) created for the DSI device then devm_drm_of_get_bridge() will return an error, also making msm_dsi_manager_ext_bridge_init() and thus DSI modesetting init fail. This way there can be no 'unconnected' MSM DSI bridges. Remove the msm_dsi_device_connected() function.
