2013-12-30ARM/cpuidle: remove __init tag from Calxeda cpuidle probe functionAndre Przywara1-1/+1
Commit 60a66e370007e8535b7a561353b07b37deaf35ba changed the Calxeda cpuidle driver to a platform driver, copying the __init tag from the _init() to the newly used _probe() function. However, "probe should not be __init." (Rob said ;-) Remove the __init tag to fix a section mismatch in the Calxeda cpuidle driver.

2013-10-02cpuidle: calxeda: add support to use PSCI callsRob Herring1-33/+6
This updates the Calxeda cpuidle driver to use PSCI calls to powergate cores. This also enables cpuidle for the ECX-2000. This could possibly become a generic PSCI driver, but there are no other PSCI users in the kernel other than mach-virt. Signed-off-by: Rob Herring <rob.herring@calxeda.com> Cc: "Rafael J.

2013-04-27cpuidle: add maintainer entryDaniel Lezcano1-1/+3
Currently cpuidle drivers are spread across different archs. As a result, there are several different paths for cpuidle patch submissions: cpuidle core changes go through linux-pm, ARM driver changes go to the arm-soc or SoC-specific trees, sh changes go through the sh arch tree, pseries changes go through the PowerPC tree and finally intel changes go through the Len's tree while ACPI idle changes go through linux-pm. That makes it difficult to consolidate code and to propagate modifications from the cpuidle core to the different drivers. Hopefully, a movement has started to put the majority of cpuidle drivers under drivers/cpuidle like cpuidle-calxeda.c and cpuidle-kirkwood.c. Add a maintainer entry for cpuidle to MAINTAINERS to clarify the situation and to indicate to new cpuidle driver authors that those drivers should not go into arch-specific directories. The upstreaming process is unchanged: Rafael takes patches for merging into his tree, but with an Acked-by: tag from the driver's maintainer, so indicate in the drivers' headers who maintains them. The arrangement will be the same as for cpufreq.

2013-04-23cpuidle: remove en_core_tk_irqen flagDaniel Lezcano1-1/+0
