drm/omap: dsi: Fix excessive stack usage

2023-03-11T15:39:52+00:00

[ Upstream commit cfca78971b9233aef0891507a98fba62046d4542 ] dsi_dump_dsi_irqs(), a function used for debugfs prints, has a large struct in its frame, which can result in: drivers/gpu/drm/omapdrm/dss/dsi.c:1126:1: warning: the frame size of 1060 bytes is larger than 1024 bytes [-Wframe-larger-than=] As the performance of the function is of no concern, let's allocate the struct with kmalloc instead. Compile-tested only.

drm/omap: dss: Fix refcount leak bugs

[ Upstream commit 8b42057e62120813ebe9274f508fa785b7cab33a ] In dss_init_ports() and __dss_uninit_ports(), we should call of_node_put() for the reference returned by of_graph_get_port_by_id() in fail path or when it is not used anymore.

drm/omap: sdi: fix bridge enable/disable

2020-11-30T09:27:57+00:00

When the SDI output was converted to DRM bridge, the atomic versions of enable and disable funcs were used. This was not intended, as that would require implementing other atomic funcs too. This leads to: WARNING: CPU: 0 PID: 18 at drivers/gpu/drm/drm_bridge.c:708 drm_atomic_helper_commit_modeset_enables+0x134/0x268 and display not working. Fix this by using the legacy enable/disable funcs.

drm/omap: force runtime PM suspend on system suspend

2020-08-04T08:10:31+00:00

Use SET_LATE_SYSTEM_SLEEP_PM_OPS in DSS submodules to force runtime PM suspend and resume. We use suspend late version so that omapdrm's system suspend callback is called first, as that will disable all the display outputs after which it's safe to force DSS into suspend.
