drm/arc: Use drm_fbdev_generic_setup()

2018-11-01T14:23:21Z

The CMA helper is already using the drm_fb_helper_generic_probe part of the generic fbdev emulation. This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). The drm_fbdev_generic_setup() call is put after drm_dev_register() in the driver. This is done to highlight the fact that fbdev emulation is an internal client that makes use of the driver, it is not part of the driver as such. If fbdev setup fails, an error is printed, but the driver succeeds probing.

drm/arcpgu: Use drm_atomic_helper_shutdown

2018-10-05T16:04:09Z

drm_plane_helper_disable is a non-atomic drivers only function, and will blow up (since no one passes the locking context it needs). Atomic drivers which want to quiescent their hw on unload should use drm_atomic_helper_shutdown() instead.

drm/arcpgu: Drop transitional hooks

drm: drop _mode_ from drm_mode_connector_attach_encoder

drm: add missing ctx argument to plane transitional helpers

2018-07-03T07:30:19Z

In commits: 34a2ab5e0689 ("drm: Add acquire ctx parameter to ->update_plane") 1931529448bc ("drm: Add acquire ctx parameter to ->plane_disable") a pointer to a drm_modeset_acquire_ctx structure was added as an argument to the method prototypes. The transitional helpers are supposed to be directly plugged in as implementations of these methods, but doing so generates a warning. Add the missing argument. A number of buggy users were added for drm_plane_helper_disable() which need to be fixed up for this change, which we do by passing a NULL ctx argument.

drm/arc: Stop consulting plane->fb

2018-05-25T17:08:27Z

We want to stop using plane->fb with atomic driver, so stop looking at it. I have no idea what this code is trying to achieve. There is no corresponding check in the enable path. Also since arc_pgu_set_pxl_fmt() will anyway oops if there is no fb I'm going to assuming that I can just remove the check entirely. There seems to be a general shortage of .atomic_check() in this driver...

drm/arcpgu: remove drm_encoder_slave

2018-01-30T17:05:25Z

drm_encoder_slave is the old way to write bridge drivers, for i2c bridges only. It's deprecated, and definitely should not be used in new drivers. This has absolutely nothing to do with the new bridge driver infrastructure implemented by drm_bridge. What's even strange is that arcpgu doesn't even use any of this, it really only wants a plain normal drm_encoder. Nuke all the surplus real estate. v2: Actually git add after compile testing ... v3: Clarify commit message and stop including drm_encoder_slave.h.
