This reverts commit ff57c6513820efe945b61863cf4a51b79f18b592. With the commit ff57c6513820 ("drm: kirin: Fix for hikey620 display offset problem") we added support for handling LDI overflows by resetting the hardware. However, its been observed that when we do hit the LDI overflow condition, the irq seems to be screaming, and we do nothing but stream: [drm:ade_irq_handler [kirin_drm]] *ERROR* LDI underflow! over and over to the screen I've tried a few appraoches to avoid this, but none has yet been successful and the cure here is worse then the original disease, so revert this for now.

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 Restructured Text 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.
