Hi!
This is a new revision of the Acer Chromebook R13 support series. It does
not offer anything new in terms of functionality, but eliminates three out
of four ugly hacks and adds a few minor cleanups; see below for details.
Thanks to Robin Murphy and CK Hu for their comments and suggestions!
I'm still looking for advice on how to implement the dual-role mmsys device
correctly; see "hack: mediatek: get mmsys to register as both DRM and clock
device" for details on this.
Like the previous revision, you can find this series at
https://github.com/uli/kernel/tree/elm-working, which also contains a config
file and several ancillary bits that are required to build a kernel
partition for the Chromebook. Instructions on how to do so (and various
other things that have to be done to get it running on your device) are
available at
https://www.elinux.org/User:Uli/Acer_Chromebook_R13_GPU_test_system (These
instructions have been written for the vendor kernel, but apply to mainline
as well, except that you won't need any extra patches.)
I appreciate your efforts to get this done. From what I understand you rebased
the patches from the chromium kernel to mainline. So you should keep the
signed-off-by from the original author and just add you signed-off-by below that.
Also it would be nice to CC these persons so that they are aware of your effort.

Changes since RFC v1:
- cmdq: remove obsolete driver; not currently used anyway
Are you sure about this? I remember that Dan (CC'ed) told me that this is one of
the requirements to get upstream working.
Dan, can you clarify please?

Matthias
- dt: remove CD GPIO from mmc1, does not seem to be correct
- mmc: remove mtk-sd.c revert hack (works fine without the CD pin)
- dsi: fix port number for drm_of_find_panel_or_bridge(), remove hack
- fbdev: add missing Signed-off-bys
- iommu: remove io-pgtable sanity check hack, has been properly fixed
- minor style fixes
