2015-03-23ARM: cpuidle: Remove duplicate header inclusionDaniel Lezcano
The cpu_do_idle() function is always used by the cpuidle drivers. That led to have each driver including cpuidle.h and proc-fns.h, they are always paired. That makes a lot of duplicate headers inclusion. Instead of including both in each .c file, move the proc-fns.h header inclusion in the cpuidle.h header file directly, so we can save some line of code.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core update from Greg KH: "Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes.

2014-11-12cpuidle: Invert CPUIDLE_FLAG_TIME_VALID logicDaniel Lezcano
The only place where the time is invalid is when the ACPI_CSTATE_FFH entry method is not set. Otherwise for all the drivers, the time can be correctly measured. Instead of duplicating the CPUIDLE_FLAG_TIME_VALID flag in all the drivers for all the states, just invert the logic by replacing it by the flag CPUIDLE_FLAG_TIME_INVALID, hence we can set this flag only for the acpi idle driver, remove the former flag from all the drivers and invert the logic with this flag in the different governor.

2013-08-14cpuidle-kirkwood.c: simplify use of devm_ioremap_resource()Julia Lawall
Remove unneeded error handling on the result of a call to platform_get_resource when the value is passed to devm_ioremap_resource(). A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression pdev,res,n,e,e1; expression ret != 0; identifier l; @@ - res = platform_get_resource(pdev, IORESOURCE_MEM, n); ... when != res - if (res == NULL) { ... \(goto l;\|return ret;\) } ... when != res + res = platform_get_resource(pdev, IORESOURCE_MEM, n); e = devm_ioremap_resource(e1, res); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Rafael J.

2013-04-26cpuidle: add maintainer entryDaniel Lezcano
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.
