Subject: [PATCH v2 00/26] drm: Add Allwinner A10 display engine support
Hi everyone,
The Allwinner SoCs (except for the very latest ones) all share the
same set of controllers, loosely coupled together to form the display
pipeline.
Depending on the SoC, the number of instances of the controller will
change (2 instances of each in the A10, only one in the A13, for
example), and the output availables will change too (HDMI, composite,
VGA on the A20, none of them on the A13).
On most featured SoCs, it looks like that:
+--------------------------------------------+
| RAM |
+--------------------------------------------+
| | | |
v | | v
+----------------+ | | +----------------+
| Frontend | | | | Frontend |
+----------------+ | | +----------------+
| | | |
v | | v
+----------------+ | | +----------------+
| Backend |<+ +>| Backend |
+----------------+ +----------------+
| |
v v
+----------------+ +----------------+---> LVDS
| TCON | | TCON |---> RGB
+----------------+ +----------------+
| +---+ +---+ |
| | | |
v v v v
+------------+ +------------+ +------------+---> VGA
| TV Encoder | | HDMI | | TV Encoder |---> Composite
+------------+ +------------+ +------------+
The current code only assumes that there is a single instance of all
the controllers. It also supports only the RGB and Composite
interfaces.
Let me know what you think,
Maxime
Changes from v1:
- Rebased on top of 4.4
- Merged the clock drivers for the display and TCON channel 0 clocks
- Replaced the container_of calls in the display reset clocks to an
inline function
- Checked the return code of of_clk_parent_fill in the clocks
drivers
- Checked the return code of of_clk_add_provider in the tcon-ch1 and
PLL3 clocks
- Added missing clocks headers
- Created a composite clock unregister function
- Moved the binding documentation to
Documentation/devicetree/bindings/display
- Added the clocks binding documentation
- Added the Olimex vendor to the list of DT vendors
- Moved to the OF graph representation and the component framework
- Moved the reset cells count check into the reset framework to
avoid duplicating the code in every xlate implementation.
- Made the reset_ops const
- Reworked the DRM cmdline mode parsing code to allow named mode
- Fixed the TV mode lookup when the mode name is not present (for
example because it was given by the userspace)
- Made the driver outputs optional (to avoid crashing when a board
doesn't have either a panel or a composite output enabled)
- Added multiple plane support with transparency
- Moved the backend registers writes commit in the CRTC atomic_flush
callback
- Removed the load / unload functions
- Removed the enabled booleans in my private structure and removed
the implicit call to disable_unused_functions in the DRM core to
push it in the drivers.
- Fixed a few bitmasks on some bitfields definition
- Fixed the RGB connector mode validation that was not testing the
right values
