2023-12-05drm/msm/mdss: Handle the reg bus ICC pathDmitry Baryshkov
Apart from the already handled data bus (MAS_MDP_Pn<->DDR), there's another path that needs to be handled to ensure MDSS functions properly, namely the "reg bus", a.k.a the CPU-MDSS interconnect. Gating that path may have a variety of effects, from none to otherwise inexplicable DSI timeouts. Provide a way for MDSS driver to vote on this bus. A note regarding vote values. Newer platforms have corresponding bandwidth values in the vendor DT files. For the older platforms there was a static vote in the mdss_mdp and rotator drivers. I choose to be conservative here and choose this value as a default.

2023-12-04Revert "drm/atomic: Loosen FB atomic checks"Dmitry Baryshkov
This reverts commit f1e75da5364e780905d9cd6043f9c74cdcf84073. 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.

2023-12-04drm/i915/dsi: Use devm_gpiod_get() for all GPIOsHans de Goede
soc_gpio_set_value() already uses devm_gpiod_get(), lets be consistent and use devm_gpiod_get() for all GPIOs. This allows removing the intel_dsi_vbt_gpio_cleanup() function, which only function was to put the GPIO-descriptors.

2023-12-04drm/bridge: migrate bridge_chains to per-encoder fileDmitry Baryshkov
Instead of having a single file with all bridge chains, list bridges under a corresponding per-encoder debugfs directory. While we are at it, also slightly improve the formatting of the bridge data: split a single line entry into multiple lines, include the symbol name of the bridge funcs and add the textual representation of the bridge ops. Example of the listing: $ cat /sys/kernel/debug/dri/0/encoder-0/bridges bridge[0]: dsi_mgr_bridge_funcs type: [0] Unknown ops: [0] bridge[1]: lt9611uxc_bridge_funcs type: [11] HDMI-A OF: /soc@0/geniqup@9c0000/i2c@994000/hdmi-bridge@2b:lontium,lt9611uxc ops: [7] detect edid hpd Reviewed-by: Neil Armstrong <neil.armstrong@linaro.org> Reviewed-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com> Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/20231203115315.1306124-3-dmitry.baryshkov@linaro.org

2023-12-04drm/bridge: add transparent bridge helperDmitry Baryshkov
Define a helper for creating simple transparent bridges which serve the only purpose of linking devices into the bridge chain up to the last bridge representing the connector. This is especially useful for DP/USB-C bridge chains, which can span across several devices, but do not require any additional functionality from the intermediate bridges.

2023-12-04drm/bridge: nxp-ptn3460: fix i2c_master_send() error checkingDan Carpenter
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.
