Hi, in preparation for the next hardware version (expected to be with TILER and without ssd2858), I have updated the device tree file names a little.
Did you test that TILER will work fine enough?
Matthijs is still testing and fixing things. He has it working on the HDMI output but has no't tested on the LCD port.
Is there some issue with ssd2858?
Yes, we are still stuck with converting the panel-mipi-debug based driver into a really working driver. There is no difference in the DSS, DSI, ssd2858 registers, but we get a black picture and slightly different timing with oscilloscope. So it must be some initialization sequence issue we have not understood yet.
If the TILER works well enough, we won't need the ssd2858 any more.
There's also errata i878 - "MPU Lockup With Concurrent DMM and EMIF Accesses" which you could hit there.
Hm. I have no errata document for that on OMAP5. The highest number I can find is ca. i820.
