Subject: [RFC PATCH v4 0/2] drm: Add generic colorkey plane properties

Changes in v4:

1) In response to Ville's Syrjälä review comments:

	- Added new "colorkey.plane_mask" property that specifies which
	  planes shall participate in color key matching operation.

	- Added short glossary-comment to drm_plane_create_colorkey_properties()
	  that clarifies 'destination' / 'source' plane terms.

	- Returned "colorkey.mask" property that was dropped from v3, looks
	  like masking is quite common among different HW and hence makes more
	  sense to have that property by default instead of having additional
	  color keying modes.

	- Changed the color keying mode name to "transparent".

2) In response to Maarten's Lankhorst review comments:

	- Added a drm_colorkey_extract_component() helper which is supposed to
	  commonize color key component value extraction code among DRM drivers.

3) In response to Russell's King review comments:

	- The doc-comment to drm_plane_create_colorkey_properties() now
	  explicitly states that "The converted value shall be *rounded up* to
	  the nearest value". Hence userspace now knows what to expect when
	  plane has a 1bpp format.

Please review, thanks.
