Hi,
This serie aims at enhancing the support for plane-wide alpha in the
drivers that are implementing it at the moment, by turning it into a
generic property and converting the drivers (rcar-du and atmel-hclcdc). It
also introduces support for it in the sun4i driver.
Let me know what you think,
Maxime
Changes from v5:
- Added back a comment about the pixel values not being pre-multiplied as
suggested by Laurent
Changes from v4:
- Removed the premultiplied alpha mention
- Added Eric Reviewed-by
Changes from v3:
- Rebased on current drm-misc-next
- Made the alpha property a 16 bits property, and have the drivers
drop the lowest 8 bits
- Removed the csv documentation, and documented it in the doc instead
Changes from v2:
- Rebased on current drm-misc-next
- Removed the patches already applied
- Split the patch implementing the automatic pipe assignment in two
Changes from v1:
- Document the behaviour on concurrent usage of the alpha property and an
alpha component in the format
- Allowed for higher alpha values
- Moved the alpha value from a helper to the struct drm_format_info
- Collected tags
- Rebased on current drm-misc-next
Maxime Ripard (5):
drm/blend: Add a generic alpha property
drm/atmel-hclcdc: Convert to the new generic alpha property
drm/rcar-du: Convert to the new generic alpha property
drm/sun4i: Add support for plane alpha
drm/docs: Remove the rcar alpha from the csv file
