Hi Dave,
please consider merging this update for the ipu-v3 mem2mem image conversion code together with a few small cleanups and fixes.

drm/imx: ipuv3-plane: add IDMAC timeout warning (2018-11-05 14:56:04 +0100)
---------------------------------------------------------------- drm/imx: update image-convert with fixes for multi-tiled scaling
Update the ipu-v3 mem2mem image-convert code, with some fixes for race conditions, alignment issues, and visual artifacts due to tile alignment and scaling factor issues when scaling images larger than hardware limitations in multiple tiles. This will allow the V4L2 mem2mem scaler driver to write output images larger than 1024x1024 pixels.
Also switch drm/imx source files to SPDX license identifiers, constify struct clk_ops in imx-tve, and add a timeout warning to the busy wait in ipu_plane_disable().
