cpufreq: rename index as driver_data in cpufreq_frequency_table

2013-06-04T12:25:59Z

The "index" field of struct cpufreq_frequency_table was never an index and isn't used at all by the cpufreq core. It only is useful for cpufreq drivers for their internal purposes. Many people nowadays blindly set it in ascending order with the assumption that the core will use it, which is a mistake. Rename it to "driver_data" as that's what its purpose is. All of its users are updated accordingly. [rjw: Changelog] Signed-off-by: Viresh Kumar Acked-by: Simon Horman Signed-off-by: Rafael J. Wysocki

PM / Runtime: Rework the "runtime idle" helper routine

2013-06-03T19:49:52Z

The "runtime idle" helper routine, rpm_idle(), currently ignores return values from .runtime_idle() callbacks executed by it. However, it turns out that many subsystems use pm_generic_runtime_idle() which checks the return value of the driver's callback and executes pm_runtime_suspend() for the device unless that value is not 0. If that logic is moved to rpm_idle() instead, pm_generic_runtime_idle() can be dropped and its users will not need any .runtime_idle() callbacks any more. Moreover, the PCI, SCSI, and SATA subsystems' .runtime_idle() routines, pci_pm_runtime_idle(), scsi_runtime_idle(), and ata_port_runtime_idle(), respectively, as well as a few drivers' ones may be simplified if rpm_idle() calls rpm_suspend() after 0 has been returned by the .runtime_idle() callback executed by it. To reduce overall code bloat, make the changes described above. Tested-by: Mika Westerberg Tested-by: Kevin Hilman Signed-off-by: Rafael J.

Merge branch 'pfc' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/sh-pinmux

2013-01-29T16:56:25Z

From Simon Horman. Based on agreement between me, Paul Mundt, Linus Walleij and Simon, we're mergning this large branch of pinctrl conversion through arm-soc, even though it contains the corresponding conversions for arch/sh. Main reason for this is tight dependencies (that will now mostly be broken) between the arch/sh and mach-shmobile implementations. There will be more of this in 3.10 to do device-tree bindings, but this is the initial conversion. * 'pfc' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas: (80 commits) sh-pfc: Move sh_pfc.h from include/linux/ to driver directory sh-pfc: Remove pinmux_info definition sh: Remove unused sh_pfc_register_info() function sh: shx3: pinmux: Use driver-provided pinmux info sh: sh7786: pinmux: Use driver-provided pinmux info sh: sh7785: pinmux: Use driver-provided pinmux info sh: sh7757: pinmux: Use driver-provided pinmux info sh: sh7734: pinmux: Use driver-provided pinmux info sh: sh7724: pinmux: Use driver-provided pinmux info sh: sh7723: pinmux: Use driver-provided pinmux info sh: sh7722: pinmux: Use driver-provided pinmux info sh: sh7720: pinmux: Use driver-provided pinmux info sh: sh7269: pinmux: Use driver-provided pinmux info sh: sh7264: pinmux: Use driver-provided pinmux info sh: sh7203: pinmux: Use driver-provided pinmux info ARM: shmobile: sh73a0: Use driver-provided pinmux info ARM: shmobile: sh7372: Use driver-provided pinmux info ARM: shmobile: r8a7779: Use driver-provided pinmux info ARM: shmobile: r8a7740: Use driver-provided pinmux info sh-pfc: Add shx3 pinmux support ...

sh-pfc: Remove unused resource and num_resources platform data fields

The fields are now unused, remove them. Signed-off-by: Laurent Pinchart Acked-by: Paul Mundt Acked-by: Linus Walleij Signed-off-by: Simon Horman

sh-pfc: Remove platform device registration

The PFC platform device is now registered by arch code, remove the legacy registration mechanism. Signed-off-by: Laurent Pinchart Acked-by: Paul Mundt Acked-by: Linus Walleij Signed-off-by: Simon Horman

sh-pfc: Support passing resources through platform device

2013-01-25T00:24:22Z

Resources should be passed through the platform device, not through platform data. Default to platform device resources and fall back to platform data resources if not available. Support for platform data resources will be removed when arch code will be converted. Signed-off-by: Laurent Pinchart Acked-by: Paul Mundt Acked-by: Linus Walleij Signed-off-by: Simon Horman

sh-pfc: Split platform device and platform driver registration

2013-01-25T00:24:22Z

Move platform driver registration to a static postcore initcall. This prepares the move of platform device registration to arch code. Signed-off-by: Laurent Pinchart Acked-by: Paul Mundt Acked-by: Linus Walleij Signed-off-by: Simon Horman

sh-pfc: Use sh_pfc_ namespace prefix through the whole driver

2013-01-25T00:24:22Z

Most of the function and structure names are prefixed by sh_pfc_. Fix the ones that are not to avoid namespace clashes (especially for functions that start with gpio_). Not included in this patch are the platform data structures, those will be reworked later. Signed-off-by: Laurent Pinchart Acked-by: Linus Walleij Signed-off-by: Simon Horman
