| * PM / Runtime: Rework the "runtime idle" helper routineRafael J. Wysocki2013-06-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <mika.westerberg@linux.intel.com> Tested-by: Kevin Hilman <khilman@linaro.org> Signed-off-by: Rafael J.

* | cpufreq: rename index as driver_data in cpufreq_frequency_tableViresh Kumar2013-06-041-2/+2
|/ | | | | | | | | | | | | | | | | 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.

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 ...

More platforms will be convered over in the next few releases. Two critical last things had to be done for this to be practical and possible: * Today each platform has its own include directory under mach-<mach>/include/mach/*, and traditionally that is where a lot of driver/platform shared definitions have gone, such as platform data structures. They now need to move out to a common location instead, and this branch moves a large number of those out to include/linux/platform_data. * Each platform used to list the device trees to compile for its boards in mach-<mach>/Makefile.boot.

| | | | | | | | | | | | | | | | | | Presently it's assumed that the irqdomain code handles the irq_desc allocation for us, but this isn't necessarily the case when we've pre-allocated IRQs via sparseirq. Previously we had a -EEXIST check in the code that attempted to trap these cases and simply update them in-place, but this behaviour was inadvertently lost in the transition to irqdomains. This simply restores the previous behaviour, first attempting to let the irqdomain core fetch the allocation for us, and falling back to an in-place domain association in the extant IRQ case. Fixes up regressions on platforms that pre-allocate legacy IRQs (specifically ARM-based SH-Mobile platforms, as SH stopped pre-allocating vectors some time ago).

Further lack of checking any sort of errors from gpio_request() resulted in boot time warnings, tripping on the FLAG_REQUESTED test-and-set in gpio_ensure_requested(). As it turns out there's no particular need to bother with the two-stage registration, as the platform bus is already available at the point that we have to start caring. As such, it's easiest to simply fold these together in to a single init path, the ordering of which is ensured through the platform's mux registration, as usual. Reported-by: Rafael J.

| | | | | | | | | | | | | | | | This follows the function support by simply doing 1 pin per group encapsulation in order to keep with legacy behaviour. This will be built on incrementally as SoCs define their own pin groups. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * sh: pfc: pinctrl legacy function support.Paul Mundt2012-07-111-33/+132
| | | | | | | | | | | | | | | | | | This maps out all of the function types to pinctrl function groups. Presently this is restricted to one pin per function to maintain compatability with legacy behaviour. This will be extended as groups are introduced and exiting users migrated.

| * sh: pfc: Rudimentary pinctrl-backed GPIO support.Paul Mundt2012-07-105-131/+437
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This begins the migration of the PFC core to the pinctrl subsystem. Initial support is very basic, with the bulk of the implementation simply being nopped out in such a way to allow registration with the pinctrl core to succeed. The gpio chip driver is stripped down considerably now relying purely on pinctrl API calls to manage the bulk of its operations. This provides a basis for further PFC refactoring, including decoupling pin functions from the GPIO API, establishing pin groups, and so forth. These will all be dealt with incrementally so as to introduce as few growing and migratory pains to tree-wide PFC pinmux users today. When the interfaces have been well established and in-tree users have been migrated off of the legacy interfaces it will be possible to strip down the core considerably, leading to eventual drivers/pinctrl rehoming.

| * sh: pfc: Shuffle PFC support core.Paul Mundt2012-07-106-17/+19
| | | | | | | | | | | | | | | | This follows the intc/clk changes and shuffles the PFC support code under its own directory. This will facilitate better code sharing, and allow us to trim down the exported interface by quite a margin. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * sh: pfc: Verify pin type encoding size at build time.Paul Mundt2012-06-201-0/+5
| | | | | | | | | | | | | | | | | | | | The encoding is tightly packed, and future changes (such as pinconf-generic support) can easily lead to a situation where we violate the encoding constraints and trample data bit/reg bits. This plugs in some sanity checks by way of a BUILD_BUG_ON() to blow up if we fail to fit. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
