[PATCH v2 0/2] Add ST-Ericsson AB8500 HWMON driver

by Hongbo Zhang

Guenter, Please check this v2 patches, thanks. Anton Vorontsov and David Woodhouse, Please have a look at this [2/2] patch, thanks. v1 -> v2 changes: - Add Documentation/hwmon/abx500 and Documentation/hwmon/abx500 - Make devices which cannot report milli-Celsius invisible - Add temp5_crit interface - Re-work the old find_active_thresholds() to threshold_updated() - Reset updated_min_alarm and updated_max_alarm at the end of each loop - Update the hyst mechamisn to make it works as real hyst - Remove non-stand attributes - Re-order the operations sequence inside probe and remove functions - Update all the lock usages to eliminate race conditions - Make attibutes index starts from 0 also changes: - Since the old [1/2] "ARM: ux500: rename ab8500 to abx500 for hwmon driver" has been merged by Samuel, so won't send it again. - Add another new patch "ab8500_btemp: export two symblols" as [2/2] of this patch set.

Test Result Summary of Calendar Week 6, 2013 for Linux Linaro ubuntu Quantal.

by Botao Sun

Calendar Week 6, 2013: Here is test result summary for Linux Linaro ubuntu Quantal image on following boards: 1) ARM Versatile Express A9; 2) Samsung Arndale; 3) TI Panda 4430; 4) TI Panda 4460; 5) ST Ericsson Snowball. Synopsis: ARM DS-5 works well on all boards except STE Snowball; Power Management test passed on both TI Panda 4430 & 4460; No display on Samsung Arndale & STE Snowball. 1. ARM Versatile Express A9 + Linux Linaro Quantal (Column J): https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AroPySpr4FnEdFNmV… It keeps exactly same status as last test result: only "Halt" & "Device Tree" test failed, all other features work well. 2. Samsung Arndale + Linux Linaro Quantal (Column D): https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AgB-fT5LL31CdGZJS… "Boot" & "Reboot" work well, HDMI display is unavailable, Power Management test is not pre-installed in image, but it's as expected, other features work well. 3. TI Panda 4430 + Linux Linaro Quantal (Column J): https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AroPySpr4FnEdEwwZ… ARM DS-5 backs to work, only "Device Tree" feature is unavailable, all others work well. Power Management test also passed on this image. 4. TI Panda 4460 + Linux Linaro Quantal (Column J): https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AroPySpr4FnEdEwwZ… Only "Device Tree" test failed, all others work well. 5. ST Ericsson Snowball + Linux Linaro Quantal (Column J): https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AroPySpr4FnEdFJ4X… "Halt" works, but many other features are unavailable, for example: HDMI, reboot, Ethernet, Device Tree and Power Management. For the previous week test summary (Linaro 13.01 Release), please refer to attachment. Thank you. Best Regards Botao Sun

[PATCH 1/3] pm-qa: collecting seperated test switches into one central file.

It is inconvenient for user to edit these seperated switches, so move them into one central file.

Hi Nathan/Rafael, Even i liked the basic idea behind the patchset, but didn't like the way it is divided into patches. For me, it is highly discouraged to undo something that you added in the same patchset. And you did exactly the same thing. Patch 2 is revert of 1 + rcu stuff. So, i would expect a single patch, i.e. merge of both patches + rebased on latest stuff. -- viresh
