Hi! What is status of OLPC-1.75 in v5.3? IIRC most of the patches went in, but I don't see suitable dts file in the tree. I tried porting one from working (4.19 or so) kernel, but it was not quite trivial. Is there time for dts to be merged?
Short answer is that it's not absolutely necessary. With a new enough OpenFirmware, the firmware will just construct a correct FDT. To upgrade your machine to the new firmware, just copy http://dev.laptop.org/~quozl/q4e00ja.rom to a FAT partition on a USB flash stick and run "flash u:\q4e00ja.rom" from the "ok" prompt. Then you'll be able to run stock mainline kernels happily. That said, it might still be useful to have a DTS file in tree (for reference, testing, machines with older firmware, etc.). I've now re- sent the MMP2 devicetree update patch set with the DTS file included and copied you on that one. As usual, I'm thankful for testing, reviews and acks. Take care! Lubo
