[PATCH] drm/msm/dsi: dsi_phy_14nm: Take ready-bit into account in poll_for_ready
by Marijn Suijten 01 Oct '21

01 Oct '21

The downstream driver models this PLL lock check as an if-elseif-else. The only way to reach the else case where pll_locked=true [1] is by succeeding both readl_poll_timeout_atomic calls (which return zero on success) in the if _and_ elseif condition. Hence both the "lock" and "ready" bit need to be tested in the SM_READY_STATUS register before considering the PLL locked and ready to go. Tested on the Sony Xperia XA2 Ultra (nile-discovery, sdm630).

[PATCH] drm/msm/dsi: Fix some reference counted resource leaks
by Christophe JAILLET 01 Oct '21

01 Oct '21

'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 autoloading for SPI devices does not use the DT ID table, it uses SPI modalises. Supporting OF modalises is going to be difficult if not impractical, an attempt was made but has been reverted, so ensure that module autoloading works for this driver by adding a SPI device ID table.

[PATCH v2 0/5] drm/msm/dp: Support multiple DP instances and add sc8180x
by Bjorn Andersson 01 Oct '21

01 Oct '21

The current implementation supports a single DP instance and the DPU code will only match it against INTF_DP instance 0. These patches extends this to allow multiple DP instances and support for matching against DP instances beyond 0. This is based on v4 of Dmitry's work on multiple DSI interfaces: https://lore.kernel.org/linux-arm-msm/20210717124016.316020-1-dmitry.barysh… With that in place add SC8180x DP and eDP controllers. Bjorn Andersson (5): drm/msm/dp: Remove global g_dp_display variable drm/msm/dp: Modify prototype of encoder based API drm/msm/dp: Support up to 3 DP controllers dt-bindings: msm/dp: Add SC8180x compatibles drm/msm/dp: Add sc8180x DP controllers .../bindings/display/msm/dp-controller.yaml | 2 + drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c | 23 +-- drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c | 60 ++++---- .../gpu/drm/msm/disp/msm_disp_snapshot_util.c | 8 +- drivers/gpu/drm/msm/dp/dp_display.c | 138 ++++++++++-------- drivers/gpu/drm/msm/msm_drv.h | 2 +- 6 files changed, 132 insertions(+), 101 deletions(-) -- 2.29.2
