The ARM Versatile and RealView platforms have enough support merged for v4.17/next that we can fully switch them all over to using the DRM PL111 driver instead of the old fbdev driver. Integrator and Versatile Express will follow. The device trees are augmented with the proper VGA bridges instead of "panels" that were never correct, the maximum memory bandwidth is augmented and these platforms can now in many cases support 1024x768 in 16bpp instead of only 640x480 with 32bpp. If the board has the IB1 or IB2 daughterboard mounted, the daughterboard display will take precedence over the VGA connector. The IB1 daughterboard which connects a number of various displays does not need any separate device tree: it will be autodetected. For the Versatile CP with the IB2 daughterboard we need to add a new device tree, as it has a system controller we need to access and a few other features we may want to make use of in the future. (It already has proper device tree bindings in place.) This has been tested on: - RealView PM11MPCore - RealView PB1176 - Versatile AB with and without the IB2 daughterboard - All applicable QEMU models: RealView EB, RealView PBA8, RealView PBX-A9 and Versatile AB. I'm planning to send this as two pull requests: one for the DTS changes and one for the defconfig changes.
