This set is part of a larger effort attempting to clean-up W=1 kernel builds, which are currently overwhelmingly riddled with niggly little warnings. Lee Jones (15): drm/xlnx/zynqmp_disp: Use correct kerneldoc formatting in zynqmp_disp drm/xlnx/zynqmp_dp: Fix function name zynqmp_dp_link_train() -> zynqmp_dp_train() drm/vkms/vkms_composer: Fix a few different kerneldoc formatting

NVIDIA GPUs include a common scripting language (devinit) that can be interpreted by a number of "engines", e.g. within a kernel-mode software driver, the VGA BIOS or an on-board small microcontroller which provides certain security assertions (the 'PMU'). This system allows a GPU programming sequence to be shared by multiple entities that would not otherwise be able to execute

Following a series of three patches, two of which have been sitting in my tree for a while, the third is the result of some inspection of an NV134 BIOS that seems to use the 0xaf upcode to upload training patterns. Please test! Roy Ps. Sorry they come from yet another e-mail address. My previous provider, eclipso, actively blocks users of git send-email. Inquiries fall on deaf ears, hence I
