We have a new channel on FreeNode for LAVA specific discussions: #linaro-lava This channel allows participants who are working with Linaro to join and just follow progress on LAVA. We should be using the same guidelines for deciding whether something belongs on #linaro or not as channels like #linaro-android currently do.

[PATCH 0/5] more clk-next fixes

by Mike Turquette

Hi all, These five patches are hopefully the final set of core framework changes for 3.5. There is the obligatory MAINTAINERS file change, three new fixes and the fixed-factor clock patch. That last patch is being reposted since three bugs were found in it (one on the list, two in my testing). If no one complains about these then I'll commit them to clk-next and (finally) send my pull request to Arnd. Note that the Orion patches aren't here, but I figure that Andrew L. probably wants to check those against the final clk-next before I pull them. Regards, Mike Mike Turquette (4): MAINTAINERS: add entry for common clk framework clk: prevent spurious parent rate propagation clk: remove COMMON_CLK_DISABLE_UNUSED clk: mux: assign init data Sascha Hauer (1): clk: add a fixed factor clock MAINTAINERS | 10 ++++ drivers/clk/Kconfig | 11 ----- drivers/clk/Makefile | 2 +- drivers/clk/clk-fixed-factor.c | 95 ++++++++++++++++++++++++++++++++++++++++ drivers/clk/clk-mux.c | 1 + drivers/clk/clk.c | 9 +++- include/linux/clk-private.h | 20 ++++++++ include/linux/clk-provider.h | 23 ++++++++++ 8 files changed, 156 insertions(+), 15 deletions(-) create mode 100644 drivers/clk/clk-fixed-factor.c -- 1.7.5.4

PM-QA update

by Hongbo Zhang

Hi all, PM-QA is updated: 1. Removed obsolete test cases under pm-qa/tastcases 2. Thermal test scripts has been merged into, but is temporarily disabled form the top 'make check', while ‘make -C thermal check’ still works for this sub-test. 3. Temporarily disabled suspend function form top 'make check', this will be enabled after fully test on LEBs later, also 'make -C suspend check' is available. Any problems you found please let me know, thanks.

Installing the armel libc on armhf

by Michael Hope

Hi there. Hopefully an easy question but I'm stumped. How do I install the armel softfp libc6 on a new Precise armhf install? I set APT::Architectures to { "armel" } and then tried a apt-get install libc6:armel but I get errors about the package not matching the host architecture. -- Michael

[PATCH] ARM: imx: Modify IMX_IO_P2V macro

by Robert Lee

A change is needed in the IMX_IO_P2V macro to allow all imx5 platforms to use common definitions when accessing registers of peripherals on the AIPS2 bus. This change was tested for mapping conflicts using the iop2v script found at git://git.pengutronix.de/git/ukl/imx-iop2v.git and by performing a bootup of a default build using imx_v6_v7_defconfig on a imx51 babbage board and imx53 loco board.

[PATCH v3 0/3] Add imx cpuidle

by Robert Lee

Add common imx cpuidle initialization functionality and add a i.MX5 and i.MX6Q platform cpuidle implementation. Based on v3.4-rc6 plus recently submitted device tree late_initcall patch: http://www.spinics.net/lists/arm-kernel/msg171620.html v3 changes: * removed file introduced in v1 no longer needed after v2 [per Shawn Guo] * re-ordered added #includes in alphabetical order [per Shawn Guo] * Remove if(!drv) check to allow handling by stack trace [per Sascha Hauer] * Added missing return value in error meesage [per Shawn Guo] * fixed (void *) casting problem pointed out Sasha Hauer. Used a different type of casting to properly give warning on improper casting: arm_pm_idle = (void (*)(void))imx5_idle; Used this casting instead of adding a dummy caller function because adding the dummy function appears to unnecessarily introduce the following additional operations: static void imx5_pm_idle(void) { a0: e1a0c00d mov ip, sp a4: e92dd800 push {fp, ip, lr, pc} a8: e24cb004 sub fp, ip, #4 imx5_idle(); ac: ebffffd3 bl 0 <imx5_idle> } b0: e89da800 ldm sp, {fp, sp, pc} v2 changes: * Removed some unnecessary spaces [per Jess Juhl] * Added return value for an error message [per Sascha Hauer] * Reworked init scheme to use device tree late_initcall [per Sascha and Shawn] * Moved imx6q and imx5 cpuidle functionality to existing files. https://lkml.org/lkml/2012/5/1/363 v1 initial submission: https://lkml.org/lkml/2012/4/16/644 Robert Lee (3): ARM: imx: Add common imx cpuidle init functionality.

[ANN] Disk upgrade on ci.linaro.org today

by Paul Sokolovsky

Hello, The Infrastructure team works on improving disk layout on Jenkins build systems to avoid common cases of errors which lead to unexpected downtime. We recently migrated android-build.linaro.org to new partition setup, and would like to proceed with ci.linaro.org. This is potentially multi-step process, so we want to start it ASAP to not risk it protruding into release rush time. So, we'd like to schedule a downtime at 14:00 UTC today, expected duration is 1 hr. Please let me know if you have any issues with that time. Thanks, Paul Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog
