* ARM: convert all "mov.* pc, reg" to "bx reg" for ARMv6+Russell King2014-07-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARMv6 and greater introduced a new instruction ("bx") which can be used to return from function calls. Recent CPUs perform better when the "bx lr" instruction is used rather than the "mov pc, lr" instruction, and this sequence is strongly recommended to be used by the ARM architecture manual (section A.4.1.1). We provide a new macro "ret" with all its variants for the condition code which will resolve to the appropriate instruction. Rather than doing this piecemeal, and miss some instances, change all the "mov pc" instances to use the new macro, with the exception of the "movs" instruction and the kprobes code. This allows us to detect the "mov pc, lr" case and fix it up - and also gives us the possibility of deploying this for other registers depending on the CPU selection.

* ARM: Remove ARCH_HAS_CPUFREQ config optionStephen Boyd2014-06-171-1/+0
| | | | | | | | | | | | | This config exists entirely to hide the cpufreq menu from the kernel configuration unless a platform has selected it. Nothing is actually built if this config is 'Y' and it just leads to more patches that add a select under a platform Kconfig so that some other CPUfreq option can be chosen. Let's remove the option so that we can always enable CPUfreq drivers on ARM platforms.

We have no major new features this time, but there are a few significant changes of how things work. The most visible one will probably be that we are now going to create platform devices rather than PNP devices by default for ACPI device objects with _HID. That was long overdue and will be really necessary to be able to use the same drivers for the same hardware blocks on ACPI and DT-based systems going forward. We're not expecting fallout from this one (as usual), but it's something to watch nevertheless. The second change having a chance to be visible is that ACPI video will now default to using native backlight rather than the ACPI backlight interface which should generally help systems with broken Win8 BIOSes. We're hoping that all problems with the native backlight handling that we had previously have been addressed and we are in a good enough shape to flip the default, but this change should be easy enough to revert if need be. In addition to that, the system suspend core has a new mechanism to allow runtime-suspended devices to stay suspended throughout system suspend/resume transitions if some extra conditions are met (generally, they are related to coordination within device hierarchy). However, enabling this feature requires cooperation from the bus type layer and for now it has only been implemented for the ACPI PM domain (used by ACPI-enumerated platform devices mostly today). Also, the acpidump utility that was previously shipped as a separate tool will now be provided by the upstream ACPICA along with the rest of ACPICA code, which will allow it to be more up to date and better supported, and we have one new cpuidle driver (ARM clps711x). The rest is improvements related to certain specific use cases, cleanups and fixes all over the place. Specifics: - ACPICA update to upstream version 20140424. That includes a number of fixes and improvements related to things like GPE handling, table loading, headers, memory mapping and unmapping, DSDT/SSDT overriding, and the Unload() operator. The acpidump utility from upstream ACPICA is included too. From Bob Moore, Lv Zheng, David Box, David Binderman, and Colin Ian King. - Fixes and cleanups related to ACPI video and backlight interfaces from Hans de Goede. That includes blacklist entries for some new machines and using native backlight by default. - ACPI device enumeration changes to create platform devices rather than PNP devices for ACPI device objects with _HID by default. PNP devices will still be created for the ACPI device object with device IDs corresponding to real PNP devices, so that change should not break things left and right, and we're expecting to see more and more ACPI-enumerated platform devices in the future. From Zhang Rui and Rafael J Wysocki. - Updates for the ACPI LPSS (Low-Power Subsystem) driver allowing it to handle system suspend/resume on Asus T100 correctly. From Heikki Krogerus and Rafael J Wysocki. - PM core update introducing a mechanism to allow runtime-suspended devices to stay suspended over system suspend/resume transitions if certain additional conditions related to coordination within device hierarchy are met. Related PM documentation update and ACPI PM domain support for the new feature. From Rafael J Wysocki. - Fixes and improvements related to the "freeze" sleep state. They affect several places including cpuidle, PM core, ACPI core, and the ACPI battery driver. From Rafael J Wysocki and Zhang Rui. - Miscellaneous fixes and updates of the ACPI core from Aaron Lu, Bjørn Mork, Hanjun Guo, Lan Tianyu, and Rafael J Wysocki. - Fixes and cleanups for the ACPI processor and ACPI PAD (Processor Aggregator Device) drivers from Baoquan He, Manuel Schölling, Tony Camuso, and Toshi Kani. - System suspend/resume optimization in the ACPI battery driver from Lan Tianyu. - OPP (Operating Performance Points) subsystem updates from Chander Kashyap, Mark Brown, and Nishanth Menon. - cpufreq core fixes, updates and cleanups from Srivatsa S Bhat, Stratos Karafotis, and Viresh Kumar. - Updates, fixes and cleanups for the Tegra, powernow-k8, imx6q, s5pv210, nforce2, and powernv cpufreq drivers from Brian Norris, Jingoo Han, Paul Bolle, Philipp Zabel, Stratos Karafotis, and Viresh Kumar. - intel_pstate driver fixes and cleanups from Dirk Brandewie, Doug Smythies, and Stratos Karafotis. - Enabling the big.LITTLE cpufreq driver on arm64 from Mark Brown. - Fix for the cpuidle menu governor from Chander Kashyap. - New ARM clps711x cpuidle driver from Alexander Shiyan. - Hibernate core fixes and cleanups from Chen Gang, Dan Carpenter, Fabian Frederick, Pali Rohár, and Sebastian Capella. - Intel RAPL (Running Average Power Limit) driver updates from Jacob Pan. - PNP subsystem updates from Bjorn Helgaas and Fabian Frederick. - devfreq core updates from Chanwoo Choi and Paul Bolle. - devfreq updates for exynos4 and exynos5 from Chanwoo Choi and Bartlomiej Zolnierkiewicz. - turbostat tool fix from Jean Delvare. - cpupower tool updates from Prarit Bhargava, Ramkumar Ramachandra and Thomas Renninger. - New ACPI ec_access.c tool for poking at the EC in a safe way from Thomas Renninger" * tag 'pm+acpi-3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (187 commits) ACPICA: Namespace: Remove _PRP method support. intel_pstate: Improve initial busy calculation intel_pstate: add sample time scaling intel_pstate: Correct rounding in busy calculation intel_pstate: Remove C0 tracking PM / hibernate: fixed typo in comment ACPI: Fix x86 regression related to early mapping size limitation ACPICA: Tables: Add mechanism to control early table checksum verification.

This contains a largeish cleanup series of the omap_l3_noc bus driver, cpuidle rework for Exynos, some reset driver conversions and a long branch of TI EDMA fixes and cleanups, with more to come next release. The TI EDMA cleanups is a shared branch with the dmaengine tree, with a handful of Davinci-specific fixes on top. After discussion at last year's KS (and some more on the mailing lists), we are here adding a drivers/soc directory. The purpose of this is to keep per-vendor shared code that's needed by different drivers but that doesn't fit into the MFD (nor drivers/platform) model.

As GPIO_PCA953X actually requires I2C, that can lead to build failures when I2C is disabled. This patch removes the duplicate symbol definitions and instead enables them from the davinci_all_defconfig file. A different question whether we actually want to automatically enable them at all or rather put them into defconfig, but that should be a separate patch.

This makes it easier to use the gpio driver on other platforms as it breaks dependency on mach-davinci. Latencies for gpio_get/set APIs will increase. On measurement, latency was found to have increased by 18 microsecond with gpiolib API as compared to inline APIs. Measurement was done on DA850 EVM for gpio_get_value() API by taking the printk timing across the call with interrupts disabled. inline gpio API with interrupt disabled [ 29.734337] before gpio_get [ 29.736847] after gpio_get Time difference 0.00251 gpio library with interrupt disabled [ 272.876763] before gpio_get [ 272.879291] after gpio_get Time difference 0.002528 Latency increased by (0.002528 - 0.00251) = 18 microsecond. While at it, remove GPIO_TYPE_DAVINCI enum definition as gpio-davinci.c is converted to Linux device driver model.

The driver does not have platform driver structure or a probe. Instead, it has pure_initcall function for initialization. The platform specific informaiton is obtained using the DaVinci specific davinci_soc_info structure. This is a problem for Device Tree (DT) implementation. As a first stage of DT conversion, we implement a probe. Additional notes: - The driver registration happens as postcore_initcall. This is required since machine init functions like da850_lcd_hw_init() make use of GPIO. - Start using devres APIs for simpler error handling.
