drm: Move simple_display_pipe prepare_fb helper into gem fb helpers

There's nothing tinydrm specific to this, and there's a few more copies of the same in various other drivers.

drm/simple-kms-helper: Plumb plane state to the enable hook

drm: simple_kms_helper: Fix .mode_valid() documentation

This fixes up the .mode_valid() vtable entry documentation by copyediting the documentation from the .mode_valid() documentation in the drm_modeset_helper_vtables.h file.

drm/simple_kms_helper: Add {enable|disable}_vblank callback support

2018-02-22T16:58:59Z

If simple_kms_helper based driver needs to work with vblanks, then it has to provide drm_driver.{enable|disable}_vblank callbacks, because drm_simple_kms_helper.drm_crtc_funcs does not provide any. At the same time drm_driver.{enable|disable}_vblank callbacks are marked as deprecated and shouldn't be used by new drivers. Fix this by extending drm_simple_kms_helper.drm_crtc_funcs to provide the missing callbacks.

drm: simple_kms_helper: Add mode_valid() callback support

2018-02-20T07:42:17Z

The PL111 needs to filter valid modes based on memory bandwidth. I guess it is a pretty simple operation, so we can still claim the DRM KMS helper pipeline is simple after adding this (optional) vtable callback.

drm: Plumb modifiers through plane init

2017-08-01T16:50:06Z

This is the plumbing for supporting fb modifiers on planes. Modifiers have already been introduced to some extent, but this series will extend this to allow querying modifiers per plane. Based on this, the client to enable optimal modifications for framebuffers. This patch simply allows the DRM drivers to initialize their list of supported modifiers upon initializing the plane. v2: A minor addition from Daniel v3: * Updated commit message * s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu) * Remove some excess newlines (Liviu) * Update comment for > 64 modifiers (Liviu) v4: Minor comment adjustments (Liviu) v5: Some new platforms added due to rebase v6: Add some missed plane inits (or maybe they're new - who knows at this point) (Daniel) Signed-off-by: Ben Widawsky Reviewed-by: Daniel Stone (v2) Reviewed-by: Liviu Dudau Signed-off-by: Daniel Stone

drm: Clarify the role of plane_state argument to drm_simple update().

2017-03-30T19:02:00Z

Like the atomic update hook it's wrapping, the plane_state is the old one, and the new one is in plane->state. Both msxfb and tinydrm use it correctly, but I mistook it for the new state in pl111 due to its naming.

drm/kms-helpers: Use recommened kerneldoc for struct member refs

2017-01-25T15:18:57Z

I just learned that &struct_name.member_name works and looks pretty even. It doesn't (yet) link to the member directly though, which would be really good for big structures or vfunc tables (where the per-member kerneldoc tends to be long). Also some minor drive-by polish where it makes sense, I read a lot of docs ... v2: Comments from Gustavo.
