* drm/bridge: ti-sn65dsi86: Check for CONFIG_PWM using IS_REACHABLE()Uwe Kleine-König2025-02-241-3/+3
| | | | | | | | | | | | | | | | | | | | Currently CONFIG_PWM is a bool but I intend to change it to tristate. If CONFIG_PWM=m in the configuration, the cpp symbol CONFIG_PWM isn't defined and so the PWM code paths in the ti-sn65dsi86 driver are not used. The correct way to check for CONFIG_PWM is using IS_REACHABLE which does the right thing for all cases CONFIG_DRM_TI_SN65DSI86 ∈ { y, m } x CONFIG_PWM ∈ { y, m, n }. There is no change until CONFIG_PWM actually becomes tristate.

* drm: bridge: ti-sn65dsi83: Add error recovery mechanismHerve Codina2025-02-131-0/+142
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases observed during ESD tests, the TI SN65DSI83 cannot recover from errors by itself. A full restart of the bridge is needed in those cases to have the bridge output LVDS signals again. Also, during tests, cases were observed where reading the status of the bridge was not even possible. Indeed, in those cases, the bridge stops to acknowledge I2C transactions. Only a full reset of the bridge (power off/on) brings back the bridge to a functional state. The TI SN65DSI83 has some error detection capabilities. Introduce an error recovery mechanism based on this detection. The errors detected are signaled through an interrupt. On system where this interrupt is not available, the driver uses a polling monitoring fallback to check for errors. When an error is present or when reading the bridge status leads to an I2C failure, the recovery process is launched. Restarting the bridge needs to redo the initialization sequence. This initialization sequence has to be done with the DSI data lanes driven in LP11 state. In order to do that, the recovery process resets the whole output path (i.e the path from the encoder to the connector) where the bridge is located.

Otherwise partially updated Audio InfoFrames could be sent out. Two cases where this rule were not followed are fixed: - In adv7511_hdmi_hw_params() make sure AUDIO_UPDATE bit is updated before/after setting ADV7511_REG_AUDIO_INFOFRAME. - In audio_startup() use the correct register for clearing AUDIO_UPDATE bit. The problem with corrupted audio infoframes were discovered by letting a HDMI logic analyser check the output of ADV7535. Note that this patchs replaces writing REG_GC(1) with REG_INFOFRAME_UPDATE. Bit 5 of REG_GC(1) is positioned within field GC_PP[3:0] and that field doesn't control audio infoframe and is read- only. My conclusion therefore was that the author if this code meant to clear bit 5 of REG_INFOFRAME_UPDATE from the very beginning.
