I think you gain much less by splitting up than you realize. Compare this from before the series:

Oh right, I didn't realize that this is just the shim. The bulk of the HDMI driver is in bridge/dw_hdmi.ko.
16K drivers/gpu/drm/imx/imxdrm.ko 16K drivers/gpu/drm/imx/imx-ipuv3-crtc.ko 12K drivers/gpu/drm/imx/imx-ldb.ko 12K drivers/gpu/drm/imx/imx-tve.ko 8.0K drivers/gpu/drm/imx/parallel-display.ko 72K total

with this after the series:
$ du -ch drivers/gpu/drm/imx/*.ko 44K drivers/gpu/drm/imx/imx-drm.ko 44K total

There are other things to consider as well, such as the additional memory overhead caused by merely having multiple modules, or all of the exported functions that unnecessarily clutter up the symbol table, and which end up slowing down every symbol lookup.
Thanks, can't argue with those numbers. I'll queue patches 3 and 4 for imx-drm.
