Planning topcs for inclusion in linux-linaro

Hi Andrey Now I'm providing a single LT topic based off linux-linaro-core-tracking (llct), and you said that you need everyone to base off the same version of llct, don't we need some kind of notification system where you announce a plan to rebuild linux-linaro and give us a version of llct to bas

Hi Viresh, Pawel's on holiday this week. I'm no expert in this area, but I ran your question past one of our platform guys. Does the following help? A "reboot" causes the motherboard micro to reset and do all its stuff like reprogramming the FPGA and then reset the core which then runs boot mon

[PATCH v4 2/3] devfreq: Add suspend and resume apis

2012-10-04 Thread Rajagopal Venkat
Add devfreq suspend/resume apis for devfreq users. This patch supports suspend and resume of devfreq load monitoring, required for devices which can idle. Signed-off-by: Rajagopal Venkat Acked-by: MyungJoo Ham --- drivers/devfreq/devfreq.c | 28 driv

[PATCH v4 3/3] devfreq: Add current freq callback in device profile

2012-10-04 Thread Rajagopal Venkat
Devfreq returns governor predicted frequency as current frequency via sysfs interface. But device may not support all frequencies that governor predicts. So add a callback in device profile to get current freq from driver. Also add a new sysfs node to expose governor predicted next target frequency

[PATCH v4 0/3] devfreq: Add support for devices which can idle

2012-10-04 Thread Rajagopal Venkat
This patchset updates devfreq core to add support for devices which can idle. When device idleness is detected perhaps through runtime-pm, need some mechanism to suspend devfreq load monitoring and resume when device is back online. patch 1 introduce core design changes - per device work, decouple

[PATCH v4 1/3] devfreq: Core updates to support devices which can idle

2012-10-04 Thread Rajagopal Venkat
Prepare devfreq core framework to support devices which can idle. When device idleness is detected perhaps through runtime-pm, need some mechanism to suspend devfreq load monitoring and resume back when device is online. Present code continues monitoring unless device is removed from devfreq core.

No problem, I'm just playing piggy-in-the-middle :) Does the Red button work when the core is just running Boot Monitor? If not then it may be a hardware problem and I'll ping the platform folks again. Otherwise it's more likely to be something going on in Linux-land and we'll need to wait for
