Aux hardware calibration sequence requires resetting the aux controller in order for the new setting to take effect. However resetting the AUX controller will also clear HPD interrupt status which may accidentally cause pending unplug interrupt to get lost. Therefore reset aux controller only when link is in connection state when dp_aux_cmd_fifo_tx() fail. This fixes Link Layer CTS cases 4.2.1.1 and 4.2.1.2. Signed-off-by:

Reduce link rate and re start link training if link training 1 failed due to loss of clock recovery done to fix Link Layer CTS case 4.3.1.7. Also only update voltage and pre-emphasis swing level after link training started to fix Link Layer CTS case 4.3.1.6. Changes in V2: -- replaced cr_status with link_status[DP_LINK_STATUS_SIZE] -- replaced dp_ctrl_any_lane_cr_done() with dp_ctrl_colco_recovery_any_ok() -- replaced dp_ctrl_any_ane_cr_lose() with !drm_dp_clock_recovery_ok() Changes in V3: -- return failed if lane_count <= 1 Signed-off-by:

DP cable should always connect to DPU during the entire PHY compliance testing run. Since DP PHY compliance test is executed at irq_hpd event context, dp_ctrl_off_link_stream() should be used instead of dp_ctrl_off(). dp_ctrl_off() is used for unplug event which is triggered when DP cable is dis connected. Changes in V2: -- add fixes statement Fixes: f21c8a27 ("drm/msm/dp: handle irq_hpd with sink_count = 0 correctly") Signed-off-by:

'of_find_device_by_node()' takes a reference that must be released when not needed anymore. This is expected to be done in 'dsi_destroy()'. However, there are 2 issues in 'dsi_get_phy()'. First, if 'of_find_device_by_node()' succeeds but 'platform_get_drvdata()' returns NULL, 'msm_dsi->phy_dev' will still be NULL, and the reference won't be released in 'dsi_destroy()'. Secondly, as 'of_find_device_by_node()' already takes a reference, there is no need for an additional 'get_device()'. Move the assignment to 'msm_dsi->phy_dev' a few lines above and remove the unneeded 'get_device()' to solve both issues.

Currently at dp_pm_resume() is_connected state is decided base on hpd connection status only. This will put is_connected in wrongly "true" state at the scenario that dongle attached to DUT but without hmdi cable connecting to it. Fix this problem by adding read sink count from dongle and decided is_connected state base on both sink count and hpd connection status. Changes in v2: -- remove dp_get_sink_count() cand call drm_dp_read_sink_count() Changes in v3: -- delete status local variable from dp_pm_resume() Changes in v4: -- delete un necessary comment at dp_pm_resume() Fixes: d9aa6571 ("drm/msm/dp: check sink_count before update is_connected status") Signed-off-by:

Add safe lut configuration for all the targets in dpu driver as per QOS recommendation. Issue reported on SC7280: With wait-for-safe feature in smmu enabled, RT client buffer levels are checked to be safe before smmu invalidation. Since display was always set to unsafe it was delaying the invalidaiton process thus impacting the performance on NRT clients such as eMMC and NVMe. Validated this change on SC7280, With this change eMMC performance has improved significantly. Changes in v2: - Add fixes tag (Sai) - CC stable kernel (Dimtry) Changes in v3: - Correct fixes tag with appropriate hash (stephen) - Resend patch adding reviewed by tag - Resend patch adding correct format for pushing into stable tree (Greg) Fixes: 591e34a0 ("drm/msm/disp/dpu1: add support for display for SC7280 target") Cc: stable@vger.kernel.org Signed-off-by:

Move setting up encoders from set_encoder_mode to _dpu_kms_initialize_dsi() / _dpu_kms_initialize_displayport(). This allows us to support not only "single DSI" and "bonded DSI" but also "two independent DSI" configurations. In future this would also help adding support for multiple DP connectors.

We are preparing to support two independent DSI hosts in the DSI/DPU code. To remove possible confusion (as both configurations can be referenced as dual DSI) let's rename old "dual DSI" (two DSI hosts driving single device, with clocks being locked) to "bonded DSI". Signed-off-by:

During board bringups its useful to have a DSI test pattern generator to isolate a DPU vs a DSI issue and focus on the relevant hardware block. To facilitate this, add an API which triggers the DSI controller test pattern. The expected output is a rectangular checkered pattern. This has been validated on a single DSI video mode panel by calling it right after drm_panel_enable() which is also the ideal location to use this as the DSI host and the panel have been initialized by then. Further validation on dual DSI and command mode panel is pending. If there are any fix ups needed for those, it shall be applied on top of this change. Changes in v2: - generate the new dsi.xml.h and update the bitfield names Signed-off-by:
