Thanks, but I wonder if it's a problem that the commit doesn't build? (i.e. git checkout f9b9cef1329c74607f33a20dce3f26e9a1f4ae96 make efm32_defconfig make fails in - arch/arm/kernel/sigreturn_codes.S with "Error: selected processor does not support ARM opcodes" and a few variations. - drivers/clocksource/time-efm32.o fails to link, because next/soc isn't a decendant of 4ff3774e451f. You can fix the latter by adding "select CLKSRC_MMIO" to ARCH_EFM32 if you want. I don't remember what is the current state of the first problem.) Best regards Uwe

The former problem is fixed in 5091333 (ARM: 7895/1: signal: fix armv7-m build issue in sigreturn_codes.S) which is in v3.13-rc3, but next/soc is based on v3.13-rc1. I suggest to wait until 4ff3774e451f hits Linus T.'s tree and then reapply the patch. Best regards Uwe

You did drop it, but when fetching today from armsoc, commit f9b9cef1329c74607f made it back into next/soc. There is only a single commit on top of it made by khilman (added to Cc:). Hint: There is an open pull request that you can substitute f9b9cef1329c74607f with. Best regards Uwe

There are still some missing parts (e.g. board support, device trees), but with these bits added on top of this patch I can successfully boot a EFM32GG-DK3750 board that uses an EFM32GG990F1024. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> --- Hello, I'd like to get this patch in for 3.14. The latest submission (v4, Message-Id:1383562853-17202-4-git-send-email-u.kleine-koenig@pengutronix.de) had some strict dependencies: - http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=7889/1 to be able to drop Makefile.boot, this is still in Status=Incoming in rmk's patch tracker. - http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=7890/1 to be able to drop the unused <mach/entry-macro.S>. This is already applied by rmk in his for-next branch, so it's not stable yet. - My series to drop <mach/timex.h> for !MULTI_PLATFORM. I'll send a pull request for that soon. - Patch "clocksource: time-efm32: Select CLKSRC_MMIO". This is part of a pull request by Daniel Lezcano that is expected to hit Linus T.'s tree for the next -rc. It currently sits as 4ff3774e451fefb1781638c76230b3cf9a206b92 in Daniel's tree at git://git.linaro.org/people/daniel.lezcano/linux.git clockevents/fixes . To make application a bit easier I added dummy files to drop the dependencies on the first three items of the list above. So it would be great if you could apply this patch when 4ff3774e4 went in. (In case you want to apply it already now, this last dependency could be work arounded, too, by adding a "select CLKSRC_MMIO" to ARCH_EFM32.) Other than that the only change since v4 is that I mention the exact board/processor combo in the changelog now.
