2016-09-22drm/sun4i: Fix the high buffer address maskMaxime Ripard1-2/+2
The highest 3bits of the 4 layers buffers are all part of the same register. However, our mask computation was wrong, leading to all the lowest register bits being removed when we use regmap_update_bits, which will lead to the buffers being set to some random part of the RAM. Fix our mask. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
2016-09-08drm/sun4i: backend: Handle the SATMaxime Ripard1-0/+3
The A33 has an block called SAT that is part of the backend that needs to be clocked and out of reset to be able for the backend to operate properly. Extend the binding to have the SAT resources listed, and claim them when the backend probes. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Acked-by: Chen-Yu Tsai <wens@csie.org>
2016-04-28drm: Add Allwinner A10 Display Engine supportMaxime Ripard1-0/+165
The Allwinner A10 and subsequent SoCs share the same display pipeline, with variations in the number of controllers (1 or 2), or the presence or not of some output (HDMI, TV, VGA) or not. Add a driver with a limited set of features for now, and we will hopefully support all of them eventually Reviewed-by: Boris Brezillon <boris.brezillon@free-electrons.com> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
