2015-03-30mfd: core: Fix platform-device name collisionsJohan Hovold-1/+1
Since commit 6e3f62f0793e ("mfd: core: Fix platform-device id generation") we honour PLATFORM_DEVID_AUTO and PLATFORM_DEVID_NONE when registering mfd-devices. Unfortunately, some mfd-drivers rely on the old behaviour of generating platform-device ids by adding the cell id also to the special value of PLATFORM_DEVID_NONE. The resulting platform ids are not only used to generate device-unique names, but are also used instead of the cell id to identify cells when probing subdevices. These drivers should be updated to use PLATFORM_DEVID_AUTO, which would also allow more than one device to be registered without resorting to hacks (see for example wm831x), but lets fix the regression first by partially reverting the above mentioned commit with respect to PLATFORM_DEVID_NONE.

Rk808 has a under voltage detect function, when the voltage of buck is under 85% the target voltage, the buck output will reset. But if the power load is too heavy, this function maybe err, when current over 4.2A, although the voltage is normal, but RK808 mistakenly think it is under 85%, and reset the buck.

In one shot mode, sequencer automatically disables all enabled steps at the end of each cycle. (both ADC steps and TSC steps) Hence these steps need not be saved in reg_se_cache for clearing these steps at a later stage. Also, when ADC wakes up Sequencer should not be busy executing any of the config steps except for the charge step. Previously charge step was 1 ADC clock cycle and hence it was ignored. TSC steps are always disabled at the end of each conversion cycle, hence there is no need to explicitly disable TSC steps by writing 0 to REG_SE.

First, one commit that broke the ACPI LPSS (Low-Power Subsystem) driver on a Dell box is reverted and there are two stable-candidate fixes for that driver. Another fix cleans up two recently added ACPI EC messages that look odd and the printk level of a noisy debug message in the core ACPI resources handling code is reduced. In addition to that we have two stable-candidate fixes for the s3c cpufreq driver, two cpuidle powernv driver updates related to Device Trees and a PNP subsystem cleanup that will allow us to get rid of some old ugliness going forward. Also there is a new blacklist entry for the ACPI backlight code. Specifics: - Revert a recent ACPI LPSS driver commit that prevented the touchpad driver from loading on Dell XPS13 (Jarkko Nikula). - Make the ACPI LPSS driver disable the I2C controllers and deassert SPI host controllers resets at startup on Intel BayTrail and Braswell SoCs in case they have been left in wrong states by the platform firmware which then may casuse fatal controller driver failures during resume from hibernation (Mika Westerberg). - Make two recently added ACPI EC messages look better (Scot Doyle). - Reduce the printk level of a recently added debug message related to ACPI resources that may become noisy in some cases (Rafael J Wysocki). - Add a new ACPI backlight blacklist entry for Samsung Series 9 (900X3C/900X3D/900X3E/900X4C/900X4D) laptops where the native backlight interface doesn't work while the ACPI based one does (Jens Reyer). - Make the PNP sybsystem's core code use __request_region() followed by __release_region() instead of __check_region() which then will allow us to get rid of the latter as it has no more users (Jakub Sitnicki). - Fix a build breakage and an issue with two __init functions that may be called after initialization in the s3c cpufreq driver (Arnd Bergmann). - Make the powernv cpuidle driver read target_residency values for idle states from a Device Tree (as we have the suitable DT bindings for that now) and improve the parsing of the powermgmt DT node in that driver (Preeti U Murthy)" * tag 'pm+acpi-3.20-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: cpuidle: powernv: Avoid endianness conversions while parsing DT cpufreq: s3c: remove last use of resume_clocks callback cpufreq: s3c: remove incorrect __init annotations ACPI / LPSS: Deassert resets for SPI host controllers on Braswell ACPI / LPSS: Always disable I2C host controllers ACPI / resources: Change pr_info() to pr_debug() for debug information ACPI / video: Disable native backlight on Samsung Series 9 laptops cpuidle: powernv: Read target_residency value of idle states from DT if available Revert "ACPI / LPSS: Remove non-existing clock control from Intel Lynxpoint I2C" ACPI / EC: Remove non-standard log emphasis PNP: Switch from __check_region() to __request_region()

Pull followup block layer updates from Jens Axboe: "Two things in this pull request: - A block throttle oops fix (marked for stable) from Thadeu. - The NVMe fixes/features queued up for 3.20, but merged later in the process. From Keith. We should have gotten this merged earlier, we're ironing out the kinks in the process. Will be ready for the initial pull next series" * 'for-linus' of git://git.kernel.dk/linux-block: blk-throttle: check stats_cpu before reading it from sysfs NVMe: Fix potential corruption on sync commands NVMe: Remove unused variables NVMe: Fix scsi mode select llbaa setting NVMe: Fix potential corruption during shutdown NVMe: Asynchronous controller probe NVMe: Register management handle under nvme class NVMe: Update SCSI Inquiry VPD 83h translation NVMe: Metadata format support
