Hi Nicolas,
Attached patch set has support for MPU DVFS (cpufreq) on OMAP4 and these are rebased against latest .38 linaro kernel. omap cpufreq driver changes are already posted to lo (https://patchwork.kernel.org/patch/589081/) and OMAP4 DVFS layer changes will be upstreamed once Basic DVFS framework is accepted.
Kindly let me know if you can merge these patches for .38 linaro kernel.
Merged.
BTW, I don't have an intimate knowledge about the things those patches touch. So in the future that would be helpful if you can gather some review acknowledgements in the form of Acked-by or Reviewed-by tags from some other people. Thanks.
Also, I got the following build breakage report:
LD .tmp_vmlinux1 arch/arm/mach-omap2/built-in.o: In function `omap_target': /opt/git/ubuntu/roc/natty/arch/arm/mach-omap2/omap2plus-cpufreq.c:118: undefined reference to `omap_device_scale' arch/arm/plat-omap/built-in.o: In function `omap_device_build_ss': /opt/git/ubuntu/roc/natty/arch/arm/plat-omap/omap_device.c:490: undefined reference to `omap_dvfs_register_device' make[2]: *** [.tmp_vmlinux1] Error 1 make[1]: *** [sub-make] Error 2 make[1]: Leaving directory `/opt/git/ubuntu/roc/natty' make: *** [/opt/git/ubuntu/roc/natty/debian/stamps/stamp-build-omap4] Error 2
I fixed it like this:
diff --git a/arch/arm/mach-omap2/Makefile b/arch/arm/mach-omap2/Makefile index 86a54ca..898fffe 100644 --- a/arch/arm/mach-omap2/Makefile +++ b/arch/arm/mach-omap2/Makefile @@ -65,7 +65,7 @@ obj-$(CONFIG_ARCH_OMAP2) += pm24xx.o obj-$(CONFIG_ARCH_OMAP2) += sleep24xx.o pm_bus.o voltage.o obj-$(CONFIG_ARCH_OMAP3) += pm34xx.o sleep34xx.o voltage.o \ cpuidle34xx.o pm_bus.o dvfs.o -obj-$(CONFIG_ARCH_OMAP4) += pm44xx.o voltage.o pm_bus.o +obj-$(CONFIG_ARCH_OMAP4) += pm44xx.o voltage.o pm_bus.o dvfs.o obj-$(CONFIG_PM_DEBUG) += pm-debug.o obj-$(CONFIG_OMAP_SMARTREFLEX) += sr_device.o smartreflex.o obj-$(CONFIG_OMAP_SMARTREFLEX_CLASS3) += smartreflex-class3.o Please confirm this is OK, or provide an additional patch.
This looks fine to me. Thanks for the fix. btw which defconfig threw up this error? I had built omap2plus_defconfig and it went all fine.
