[PATCH v2 0/6] add full platform dt clock support for mx51 babbage

by Shawn Guo

This patch set is to add full platform dt clock support for mx51 babbage, based on Grant's devicetree/test tree. All mx51 non-dt clocks in clock-mx51-mx53.c are translated to dt ones. Regards, Shawn Changes since v1: * unify the references to clocks that could be created statically and dynamically, so that we do not have to duplicate functions * use for_each_matching_node suggested by Grant to match clock creating functions * reserve 'data' of device_node structure and use new one 'clk' * change macro ALLOC_CLK_LOOKUP and ADD_CLK_LOOKUP to functions * fix codes that will break existing board support * use clock provider 'src-clock' and 'dep-clock' * fix up aips and spba node name to remove address info (suggestion given by Grant on Jason's patch) Shawn Guo (6): arm/dts: babbage: add all available clock nodes arm/mxc: add clk member 'rate' to ease dt fixed-clock support dt: add new member 'clk' into device_node arm/dt: mx51: dynamically add clocks per dt nodes arm/dt: mx5: change timer init function to dt clock way of/clock: eliminate function __of_clk_get_from_provider arch/arm/boot/dts/babbage.dts | 501 +++++++++++- arch/arm/mach-mx5/Makefile | 2 +- arch/arm/mach-mx5/board-dt.c | 9 +- arch/arm/mach-mx5/clock-dt.c | 52 -- arch/arm/mach-mx5/clock-mx51-mx53.c | 1433 +++++++++++++++++++++++++++++++- arch/arm/plat-mxc/include/mach/clock.h | 4 + drivers/of/clock.c | 23 +- include/linux/of.h | 1 + 8 files changed, 1913 insertions(+), 112 deletions(-)

help: Overo Problem with CONFIG_SMP=y and mpurate

by Andy Doan

I have an Overo Tide that is capable of running at 720Mhz. It defaults to 600Mhz, but the mpurate kernel command line argument allows it to overridden. The problem is that Linaro kernels (with the Linaro .config) always show 499.92 BogoMIPS in /proc/cpuinfo regardless of what I pass as the mpurate. I've discovered that by disabling CONFIG_SMP (Linaro defaults this to 'y') the problem goes away. I'm not sure how to go about fixing this, but its been noticed by the Gumstix mailing list that Linaro builds for Overo seem sluggish. Does anyone have any ideas what might cause this, or any ideas where I might start looking? FYI - the LP bug is: 739582 thanks, -andy

Call for testing: Linaro 11.05 Beta Candidate

by Jamie Bennett

Hi, In preparation for the release of Linaro 11.05 Beta images on Thursday a suitable candidate has been selected for testing. If you have supported hardware, as found on: http://releases.linaro.org/platform/linaro-n/hwpacks/beta/ please help our initiative by testing the official Linaro Evaluation Build (LEB): Ubuntu Desktop: http://releases.linaro.org/platform/linaro-n/ubuntu-desktop/beta/ and our Developer images: Nano: http://releases.linaro.org/platform/linaro-n/nano/beta/ ALIP: http://releases.linaro.org/platform/linaro-n/alip/beta/ Developer Tools: http://releases.linaro.org/platform/linaro-n/developer/beta/ As a side note, hwpacks that have an -lt- in their name are outputs from the Linaro Landing teams, using some of their components. Make your way to: http://wiki.linaro.org/Releases/MilestoneBuilds for an explanation on how to test and submit your results to the QA tracker at: http://qatracker.linaro.org For an explanation of how to use the qatracker please see: https://wiki.linaro.org/QA/QATracker Regards, Jamie. -- Linaro Release Manager | Platform Project Manager

[NOTES] Minutes & Actions: Kernel Working Group meetings of March 28, 2011

by Mounir Bsaibes

Enclosed you'll find a link to the agenda, minutes, actions and IRC logs from the Linaro kernel working group weekly meetings of March 28, 2011. https://wiki.linaro.org/WorkingGroups/KernelConsolidation/Meetings/2011-03-… == Summary == * Nico will rebase linaro-2.6.38 the current linaro tree is based on 2.6.38-rc5 * Device Tree * Grant has sent a set of patches to John Rigby & the u-boot list which fixes up some things and enables dt support on most of the platforms we care about. Once those fixes are picked up d t should be enabled by default in the u-boot images produced by Linaro. Have to wait until it hits Nico's tree to complete the testing. Grant is pushing out a tree with the panda/beagle/samsung patches tonight will ask npitre to pull. * Bugs * From the bugs without assignee, the remaining bug without patch is 712175. * The Panda power off is fixed * The imprecise abort on Panda with display is fixed * Arnd posted the fix from Uli for 615974 "Interrupted system call handling" * Actions * 11.11 cycle: Everyone to take a look at the high-level requirements on the kernel from the TSC meeting: https://wiki.linaro.org/TSC/2011-03-16/Kernel, Paul will need to come back to TSC with a response.
