The MDSS device is created before the MSM driver attempts to bind the sub components. If any of the components return -EPROBE_DEFER the MDSS device is destroyed and tried again later. If this happens the dpu_mdss_isr interrupt created from the DPU MDSS is not freed when the MDSS device is destroyed and has a risk of triggering later and hitting a fault by accessing a mmio region that no longer exists. Even if the interrupt isn't triggered by accident when the device attempts to reprobe it would error out when it tries to re-register the interrupt so unconditionally removing it in the destroy is the right move. Switch the device managed dpu_mdss_isr to be unmanaged and add a free_irq() in the mdss destroy function. Reviewed-by:

The atomic_check is a bit too aggressive with respect to planes which leave the active area. This caused a bunch of log spew when the cursor got to the edge of the screen and stopped it from going all the way. This patch removes the conservative bounds checks from atomic and clips the dst rect such that we properly display planes which go off the screen. Changes in v2: - Apply the clip to src as well (taking into account scaling) Changes in v3: - Use drm_atomic_helper_check_plane_state() to clip src/dst Cc: Sravanthi Kollukuduru <skolluku@codeaurora.org> Cc: Jeykumar Sankaran <jsanka@codeaurora.org> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

That corresponds to the integer 16. That is then indexed into drm_encoder_enum_list in drm_encoder_init() to look up the name of the encoder. If you're still following along, that's an encoder not a connector! We really want to use DRM_MODE_ENCODER_DSI (integer 6) instead of DRM_MODE_CONNECTOR_DSI here, or we'll go out of bounds of the encoder array. Pass the right thing and everything is fine.

Sean Paul authored
Currently msm_dsi->id is initialized to 0 during kzalloc. If bind fails for a secondary dsi device before its id can be properly set (such as during dt parsing), the id will point to the primary dsi device, causing its reference to be removed from dsi_manager's global (msm_dsim_glb) array. This patch initializes the id to -1 and checks for negative in the manager cleanup. Cc: Doug Anderson <dianders@chromium.org> Reviewed-by:

To make that clear to Clang without explicitly casting these values, change id's type to uint8_t in pp_atomfwctrl_get_clk_information_by_clkid so no conversion happens.

This reverts commit 3510e7a7. During the 4.19 merge window for drm-misc, two patches critical to supporting the display pipeline on the Allwinner R40 SoC were missed. They were applied later but missed the merge window deadline. As a result 4.19-rc1 kernel would crash on the R40 when it couldn't parse the new device tree structure. We ended up removing support for the R40 display pipeline for 4.19. Since the missing patches are already merged for 4.20, we can now revert the commit that removed support. Signed-off-by:
