Add functions drm_fb_cma_fbdev_init(), drm_fb_cma_fbdev_fini() and drm_fb_cma_fbdev_init_with_funcs(). These functions relies on the fact that the drm_fb_helper struct is stored in dev->drm_fb_helper_private so drivers don't need to store it.

fb_helper is being dereferenced before it is null checked, hence there is a potential null pointer dereference. Fix this by moving the pointer dereference after fb_helper has been null checked.

Now that we have all required bits, add support for YUV formats. DRM subsystem doesn't know YUV411 semi-planar format, so leave that out for now. Signed-off-by:
-
Jernej Skrabec authored
Basic principle of operation when using YUV framebuffer is that chroma planes have to be upscaled to same size as luma. Because of that, expand DE2 scaler library to support that. BSP driver uses another set of FIR filter coefficients for YUV planes. Signed-off-by:

DE2 have many CSC units - channel input CSC, channel output CSC and mixer output CSC and maybe more. Fortunately, they have all same register layout, only base offsets differs. Add support only for channel output CSC for now. Signed-off-by:
-
Jernej Skrabec authored
Base addresses of channel output CSC (CCSC) depends whether mixer in question is first or second and if it is second, if supports VEP or not. This new property will tell which set of base addresses to take. Signed-off-by:

No all SoCs support scaling on all channels. For example, V3s support scaling only on VI channels. Because of that, add additional configuration bitmask which tells which channel support scaler. Signed-off-by:

This commit adds basic support for VI planes. They are meant for video overlay and because of that they support YUV formats too. However, using YUV format is not straightforward, so only RGB formats are supported for now. Signed-off-by:
-
Jernej Skrabec authored
Till now, DE2 driver supported only UI planes. Before we add support for VI planes, lets split out UI layer specific code from common parts. This commit does the following: - renames sun8i_layer.c to sun8i_ui_layer.c - moves UI channel specific code to sun8i_ui_layer.c - moves common code from sun8i_layer.c to sun8i_mixer.c - renames function and structure names so it is apparent where they belong to No functional change is made.

Currently only a few RGB formats are supported by the DE2 driver. Add support for all formats supported by the HW. Signed-off-by:

Support for multiple UI planes can now be easily enabled just by adding more planes with different index. For now, add immutable zpos property. Signed-off-by:

There is no point having code which sets interlace mode of mixer in channel related function. Interlace mode will only change when CRTC state will change, so let's move it to the block which is executed only when primary plane state is changed. Signed-off-by:
-
Jernej Skrabec authored
Channel size should be set every time plane is changed, not only when primary plane changes. Current code works only because only one (primary) plane is supported at the moment. Signed-off-by:

Line width is a property of a framebuffer and it belongs to sun8i_mixer_update_layer_buffer(). This will became even more obvious when support for multi-plane formats will be added. Signed-off-by:

Now that we have properly clipped coordinates in plane state structure, use them. This also fixes bug where source x and y were adjusted for negative value, but width and height weren't. It wasn't discovered because primary plane usually doesn't have negative coordinates. Signed-off-by:
-
Jernej Skrabec authored
Since current DE2 driver doesn't know how to scale yet, add atomic check function which checks that. Nice side effect of that function is that populates clipped coordinates and checks visibility of the plane. That data will be used in the future. Signed-off-by:
-
Jernej Skrabec authored
Till now, plane selection was hardcoded to first overlay in first UI channel and layer parameter is unused. Rename and add parameters to layer functions so they would represent HW more accurately and start using then. It turns out that overlays don't fit well in current DRM design, because they can't be blended together or scaled independetly when they are set to same channel. Because of that, always use only first overlay in each channel. Signed-off-by:
-
Jernej Skrabec authored
If we want to support multiple planes in the future, code which enables pipe has to be moved to appropriate place and it must depend on channel id instead of being hardcoded. Side effect of that rework is definition of default Z position. For now, put first channel at the bottom, second above it and so on. Signed-off-by:

Now that some knowledge of DE2 is gained, rename or add some macros to make code more readable. Max channel macro is removed, since it is not used and it is not clear if it has right value. Structures in BSP driver shows possibility of 5 channels maximum although there is no SoC with such configuration. Signed-off-by:

Jernej Skrabec authored
BSP driver always sets blend mode for all channels, no matter if they are really used or not. Do the same here. The exact meaning of the value is not exactly known, but BSP driver mentions "SRC OVER" and by digging through code some more info can be found. Signed-off-by:
