2020-09-10disp: msm: dp: fix dp-mst stream double disabled issueXiaowen Wu
There is a corner case when dp-mst stream is disabled twice: 1. stream 1 is enabled 2. cable plugged out, stream 1 is disabled by kernel 3. cable plugged in, enable stream 0 first 4. disable stream 1 Stream 1 is double disabled and will cause hw crash. This change will add the check and skip stream_off if already disabled.

2020-09-09disp: msm: read mdp intf line count and trigger dma accordinglyHarigovindan P
This change reads the video line count from MDP_INTF_LINE_COUNT register and checks whether DMA trigger happens close to the schedule line. If it is not close to the schedule line, then DMA command transfer is triggered. Without this change there is a chance that when 2 DSI's with broadcast, schedule enabled, the DMA command gets triggered close to the schedule line which could cause DMA timeout.

2020-08-11Revert "disp: msm: dsi: update args for mipi_dsi_dcs_set_display_brightness"Rajeev Nandan
This reverts commit a54fdd7a6bad990471ace7126e7c5301654f204f which was added because of upstream android-kernel API change 8a744ca6639c. In latest android-kernel revision, the commit 8a744ca6639c ("ANDROID: drm/dsi: Fix byte order of DCS set/get brightness") got reverted, which was modifying the upstream API and was making hard to reconcile it to android-4.19 without breaking APIs for GKI. Android kernel has rolled back the upstream API change and suggested to implemnet it in downstream side. The MIPI brightness byte ordering issue is already been taken care in current dsi driver using bl_inverted_dbv panel config flag.

2020-08-07disp: msm: clear dma done interrupt status for slave controllerHarigovindan P
When Broadcast is enabled, DMA_DONE bit gets set for slave controller on command transfer completion but it is not getting cleared. Due to this, DMA transfer failures on slave controller are not getting caught. This patch add supports for clearing DMA_DONE for slave controller on every successful transfer. This also prints error if transfer fails on slave controller. Change-Id: I61ce7b2d8be323adc70d888b5a2416afd9ae9fac Signed-off-by: Harigovindan P <harigovi@codeaurora.org>

2020-07-28disp: msm: dsi: update args for mipi_dsi_dcs_set_display_brightnessRajeev Nandan
The upstream MIPI DSC set/get brightness api has been changed, and now it requires one extra argument which is number of parameters (bytes) to encode brightness value in. The MIPI specification states that one parameter shall be sent for devices that support 8-bit brightness levels. For devices that support brightness levels wider than 8-bit, two parameters shall be sent. Change-Id: I08aabf70207d5b7ab79966a1f12fe18b83c34721 Signed-off-by: Rajeev Nandan <rajeevny@codeaurora.org>

Add changes to modify in_clone_mode setting post CWB detection logic and after commit failure cases. This change handles two error cases. 1) When there is a WB commit during CWB session, we fail the WB commit as part of atomic_check but in_clone_mode setting in wb phys_enc is not restored to its original value. The previous CWB session is not disabled yet in HW and leads to HW timeouts. 2) If there is an CWB done IRQ scheduled and there is a atomic_check for CWB encoder happening, the CWB done irq triggers an incorrect fence event where the release fence of primary crtc gets signalled early.

2020-07-14disp: msm: sde: serialize rm reserve for check only commitPrabhanjan Kandula
During back to back mode set, current driver logic fails atomic check during resource allocation with test only if previous commit also with modeset, has tagged resources for allocation but did not commit the resources yet. Since client invoking atomic check before previous mode set commit complete is an expected scenario now, instead of failing atomic check, this change allows resource allocation for next commit also go through by polling till the first mode set is complete.

Sometimes the link clock is not getting locked when dp display is resumed from PM suspend. This is causing NOC error when registers in link clock domain are accessed without proper checks. The set_colorspace, config_hdr and update_pps connector ops are accessing the registers in link clock domain without checking if the necessary clocks are enabled. These changes will ensure the DP stream clocks are not enabled when link clock enable fails and prevents the connector ops from accessing the registers whose clocks are not enabled.
