2015-02-04sh: intc: Confine SH_INTC to platforms that need itGeert Uytterhoeven2-3/+6
Currently the sh-intc driver is compiled on all SuperH and non-multiplatform SH-Mobile platforms, while it's only used on a limited number of platforms: - SuperH: SH2(A), SH3(A), SH4(A)(L) (all but SH5) - ARM: sh7372, sh73a0 Drop the "default y" on SH_INTC, make all CPU platforms that use it select it, and protect all sub-options by "if SH_INTC" to fix this.

2015-02-04drivers: sh: pm_runtime implementation needs to suspend and resume devicesBen Dooks1-2/+35
If we override the platform bus calls for pm_runtime then we end up with the calls to the devices' suspend and resume methods ignored in favour of the bus ones. Change to calling the pm_runtime calls to suspend and resume the devices specifically in the drivers/sh/pm_runtime.c implementation to allow any device that may want to run power management to do so. Note, all the current sh driver implementations do not use their own power management code so this is not a major implementation issues. This also brings the implementation into line with the versions used by the Davinci and Keystone PM domain code, so once fully tested these implementations could be merged together.

2015-02-04drivers: sh: compile drivers/sh/pm_runtime.c if ARCH_SHMOBILE_MULTIGeert Uytterhoeven2-7/+27
If the kernel is built to support multi-ARM configuration with shmobile support built in, then drivers/sh is not built. This contains the PM runtime code in drivers/sh/pm_runtime.c, which implicitly enables the module clocks for all devices, and thus is quite essential. Without this, the state of clocks depends on implicit reset state, or on the bootloader. If ARCH_SHMOBILE_MULTI then build the drivers/sh directory, but ensure that bits that may conflict (drivers/sh/clk if the common clock framework is enabled) or are not used (drivers/sh/intc), are not built. Also, only enable the PM runtime code when actually running on a shmobile SoCs that needs it. ARCH_SHMOBILE_MULTI was added a while ago by commit efacfce5f8a523457e9419a25d52fe39db00b26a ("ARM: shmobile: Introduce ARCH_SHMOBILE_MULTI"), but drivers/sh was compiled for both ARCH_SHMOBILE_LEGACY and ARCH_SHMOBILE_MULTI until commit bf98c1eac1d4a6bcf00532e4fa41d8126cd6c187 ("ARM: Rename ARCH_SHMOBILE to ARCH_SHMOBILE_LEGACY").

2013-06-04cpufreq: rename index as driver_data in cpufreq_frequency_tableViresh Kumar1-2/+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. [rjw: Changelog] Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Acked-by: Simon Horman <horms+renesas@verge.net.au> Signed-off-by: Rafael J.

2013-06-03PM / Runtime: Rework the "runtime idle" helper routineRafael J. Wysocki1-1/+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.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM soc multiplatform enablement from Olof Johansson: "This is a pretty significant branch. It's the introduction of the first multiplatform support on ARM, and with this (and the later branch) merged, it is now possible to build one kernel that contains support for highbank, vexpress, mvebu, socfpga, and picoxcell. 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. Both of the above changes will mean that there are some merge conflicts to come (and some to resolve here). It's a one-time move and once it settles in, we should be good for quite a while. Sorry for the overhead."

2012-09-25sh: pfc: Fix up GPIO mux type reconfig case.Paul Mundt1-0/+2
Some drivers need to switch pin states between GPIO and pin function at runtime, which was inadvertently broken in the pinctrl driver for GPIOs being bound to a specific direction. This fixes up the request path to ensure that previously configured GPIOs don't cause us to inadvertently error out with an unsupported mux on reconfig, which in practice is primarily aimed at trapping pull-up/down users that have yet to be implemented under the new API. Fixes up regressions in the TPU PWM driver, amongst others.

2012-09-18sh: pfc: Release spinlock in sh_pfc_gpio_request_enable() error pathLaurent Pinchart1-1/+2
The sh_pfc_gpio_request_enable() function acquires a spinlock but fails to release it before returning if the requested mux type is not supported. Fix this. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2012-09-14ARM: shmobile: move custom gpio functions to sh-gpio.hRob Herring1-0/+1
Move custom shmobile gpio code to a sh-gpio.h to remove the dependency on mach/gpio.h. shmobile always uses gpiolib, so we can remove __GPIOLIB_COMPLEX define from mach/gpio.h.

2012-08-09sh: intc: Handle domain association for sparseirq pre-allocated vectors.Paul Mundt1-4/+23
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).

2012-08-01sh: pfc: Fix up init ordering mess.Paul Mundt1-17/+15
Commit ca5481c68e9fbcea62bb3c78ae6cccf99ca8fb73 ("sh: pfc: Rudimentary pinctrl-backed GPIO support.") introduced a regression for platforms that were doing early GPIO API calls (from arch_initcall() or earlier), leading to a situation where our two-stage registration logic would trip itself up and we'd -ENODEV out of the pinctrl registration path, resulting in endless -EPROBE_DEFER errors. 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.
