But just to state it in terms of what happened on the local testbed here when I tried it: - CM-T3517 booting will break since there's no .dts file for it. Are there other boards that will be affected here too? - 2430SDP NFS root will hang during boot, presumably due to the lack of the smc91x patch that is mentioned below - Dynamic idle PM tests will fail, due to the lack of the first two patches that Tony mentioned. (This is also a problem now for 37xxevm in v3.13-rc.) - The N800 isn't booting here with a concatenated uImage+dtb - but maybe I'm doing something wrong with this one. Best if the pull request were to explicitly state the known regressions with this series, in terms of specific boards and configurations. That way, people will know what to expect. > ---------------------------------------------------------------- > We can now finally make mach-omap2 to boot with device tree only and get > rid of over 20k lines of platform init code that way. > > Most basic devices already work using device tree based initialization > and the remaining devices can be initialized using platform data > with pdata-quirks.c. > > So for most missing boards it's just a question of adding a .dts file > that should be fairly similar to one of the existing .dts files as > we've tried to cover all basic omap3 board types. > > For people getting started updating their board files to for device > tree, there are some basic instructions in commit 8dc8b3ddf5d7 > (ARM: OMAP2+: Remove legacy omap3 board-*.c files and make mach-omap2 > DT only for booting). > > Please also note that there are also some related fixes making their way > into the mainline kernel that are needed for some use cases: > > PM off-idle for omap3 and wake-up events need the following two patches: > > [PATCH] of/platform: Fix no irq domain found errors when populating interrupts > http://lkml.org/lkml/2013/11/22/520 > > [PATCH] ARM: dts: Fix omap serial wake-up when booted with device tree > http://www.spinics.net/lists/devicetree/msg13374.html > > EMAC Ethernet on am3517 boards needs: > > [PATCH] net: davinci_emac: Fix platform data handling and make usable for am3517 > http://patchwork.ozlabs.org/patch/296351/ > > Ethernet for boards using smc91x needs: > > [PATCH v2] net: smc91x: Fix device tree based configuration so it's usable > http://www.spinics.net/lists/netdev/msg258913.html > (snip) - Paul -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
