[linux-sunxi] [PATCH] ARM: dts: sun8i: Base Orange Pi Plus dts on the Orange Pi 2 dts

The Orange Pi Plus really is an Orange Pi 2 extended with: 1) A sata <-> usb bridge connected to ehci3 2) An eMMC on mmc2 3) An external gigabit ethernet phy instead of the integrated 100Mbit phy This commit changes the dts to reflect this by making it include the Orange Pi 2 dts and then adding

[linux-sunxi] [PATCH v3 15/19] drm: sun4i: Add composite output

Some Allwinner SoCs have an IP called the TV encoder that is used to output composite and VGA signals. In such a case, we need to use the second TCON channel. Add support for that TV encoder. Signed-off-by: Maxime Ripard --- drivers/gpu/drm/sun4i/Makefile |

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

The TCON, tv-encoder and display engine backends and frontends are combined to create our display pipeline. Add them to the R8 DTSI. It's supposed to be perfectly compatible with the A10s and A13, but since we haven't tested it on them yet, it's safer to just enable it on the R8. Eventually, it
