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 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

base-commit: d31b5c91a27b768ee221fe677eb0b18b4cfb9df8
Some drivers duplicate the logic to create a property to store a per-plane alpha.
This is especially useful if we ever want to support extra protocols for Wayland like: https://lists.freedesktop.org/archives/wayland-devel/2017-August/034741.html
Let's create a helper in order to move that to the core.
