drm/of: Make drm_of_find_panel_or_bridge() fail when the device is disabled

2018-07-10T15:59:05Z

There's no point searching for a drm_bridge or drm_panel if the OF node we're pointing has a status property that is not "okay" or "ok". Just return -ENODEV in this case.

drm/panel: Make of_drm_find_panel() return an ERR_PTR() instead of NULL

2018-07-10T15:59:05Z

Right now, the DRM panel logic returns NULL when a panel pointing to the passed OF node is not present in the list of registered panels. Most drivers interpret this NULL value as -EPROBE_DEFER, but we are about to modify the semantic of of_drm_find_panel() and let the framework return -ENODEV when the device node we're pointing to has a status property that is not equal to "okay" or "ok". Let's first patch the of_drm_find_panel() implementation to return ERR_PTR(-EPROBE_DEFER) instead of NULL and patch all callers to replace the '!panel' check by an 'IS_ERR(panel)' one.

Function is useful when drm_of_find_possible_crtcs() can't be used and custom parsing is needed. This can happen for example when there is a node with multiple muxes between crtc and encoder.

drm/drm_of: Move drm_of_panel_bridge_remove_function into header.

2017-10-13T14:59:36Z

Core drm shouldn't depend on anything in drm-kms-helper, or the drm module will fail to load. insmod drm fails with [ 6087.674390] drm: Unknown symbol drm_panel_bridge_remove (err 0) which is defined in drm_kms_helper.ko This call was added by commit c70087e8f16f ("drm/drm_of: add drm_of_panel_bridge_remove function"), and the fix is defining it in the drm_of.h header, to break the circular dependency.

drm/drm_of: add drm_of_panel_bridge_remove function

2017-10-10T09:32:43Z

This function is the pendant of drm_of_find_panel_or_bridge() to remove a previously allocated panel_bridge. Given a specific port and endpoint it remove the panel bridge. Since drm_panel_bridge_remove() will check that bridge parameter is not NULL and is a real drm_panel_bridge and no a simple bridge it is safe to call it directly.

The callers expect "panel" to be initialized, but that isn't true if we return -ENODEV. It causes bugs like: drivers/gpu/drm/tve200/tve200_drv.c:83 tve200_modeset_init() error: uninitialized symbol 'panel'.
