Revert "drm/mgag200: Add vblank support"
This reverts commit 6c9e14ee9f519ee605a3694fbfa4711284781d22. This reverts commit d5070c9b29440c270b534bbacd636b8fa558e82b. This reverts commit 89c6ea2006e2d39b125848fb0195c08fa0b354be. The VLINE interrupt doesn't work correctly on G200SE-A (at least). We have also seen missing interrupts on G200ER. So revert vblank support. Fixes frozen displays and warnings about missed vblanks. [ 33.818362] [CRTC:34:crtc-0] vblank wait timed out From the vblank code, the driver only keeps the register constants and the line that disables all interrupts in mgag200_device_init(). Both is still useful without vblank handling.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the reStructuredText markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
