2014-07-23extcon: sm5502: Add support new SM5502 extcon device driverChanwoo Choi
This patch add new SM5502 MUIC(Micro-USB Interface Controller) device by using EXTCON subsystem. The extcon-sm5502 driver is capable of identifying the type of the external power source and attached accessory. An external power sources, such as Deticated Charger or a standard USB port, are able to charge the battery in the smart phone via the connector. Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>
2014-07-23extcon: arizona: Get MICVDD against extcon deviceCharles Keepax
Previously we would do a regulator get against the main Arizona device to obtain the MICVDD regulator. Arizona is an MFD device and normally MICVDD will be supplied by one of its children (the arizona-micsupp regulator). As devres destruction for the MFD device will run after all its children have been destroyed, the regulator will be destroyed before devres calls regulator_put. This causes a warning from both the destruction of the child node, as the regulator is still open, and from the put of the regulator as the regulator device has already been destroyed. A simple fix here is to get the regulator against the extcon device itself such that devres runs when the child is destroyed. This has the additional benefit that if for some reason the extcon driver is unloaded the regulator reference won't hang around until the MFD is unloaded.

Add partial support for `INSN_CONFIG_DIGITAL_TRIG`, but only for edge detection.

2014-07-22staging: comedi: ni_65xx: don't invert outputs by defaultIan Abbott
This driver currently inverts the outputs for the DO (digital output) subdevice for some of the boards it supports, indicated by the `invert_outputs` member in the board-specific data being initialized to 1. It seems this driver shouldn't really be inverting outputs for these boards at all, but has done so since the driver was first written back in October 2006. I've had confirmation that for the PCI-6515 at least, the output voltage levels are opposite to the values set by the user program. The driver by Jon Grierson originally supported only PCI-6514 and PXI-6514 (and was originally called "ni_6514"). The driver was based on "ni_6527", which is where the inversion of outputs appears to have come from. Over a period of a few days, the driver was enhanced by Frank Mori Hess to support other boards. Some of these plainly didn't require inverted outputs and some guesswork was used to decide which boards should have inverted outputs. Some of the boards in question are described in the manual as having "Sink Outputs" and others are described as having "Source Outputs", but this does not correspond in any way with which boards are marked as having inverted outputs, so the criterion that Frank used is a bit of a mystery! Change the driver so it doesn't invert the outputs of these by boards by default, but add a module parameter, "legacy_invert_outputs", that can be set to 'true' to restore the old behaviour. Also rename the `invert_outputs` member of `struct ni_65xx_board` to `legacy_invert`. Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2014-07-22acpi, apei, ghes: Factor out ioremap virtual memory for IRQ and NMI context.Tomasz Nowicki
GHES currently maps two pages with atomic_ioremap. From now on, NMI is architectural depended so there is no need to allocate an NMI page for platforms without NMI support. To make it possible to not use a second page, swap the existing page order so that the IRQ context page is first, and the optional NMI context page is second. Then, use HAVE_ACPI_APEI_NMI to decide how many pages are to be allocated.

2014-07-22acpi, apei, ghes: Make NMI error notification to be GHES architecture extension.Tomasz Nowicki
Currently APEI depends on x86 architecture. It is because of NMI hardware error notification of GHES which is currently supported by x86 only. However, many other APEI features can be still used perfectly by other architectures. This commit adds two symbols: 1. HAVE_ACPI_APEI for those archs which support APEI. 2. HAVE_ACPI_APEI_NMI which is used for NMI code isolation in ghes.c file. NMI related data and functions are grouped so they can be wrapped inside one #ifdef section. Appropriate function stubs are provided for !NMI case. Note there is no functional changes for x86 due to hard selected HAVE_ACPI_APEI and HAVE_ACPI_APEI_NMI symbols.

2014-07-22apei, mce: Factor out APEI architecture specific MCE calls.Tomasz Nowicki
This commit abstracts MCE calls and provides weak corresponding default implementation for those architectures which do not need arch specific actions. Each platform willing to do additional architectural actions should provides desired function definition. It allows us to avoid wrap code into #ifdef in generic code and prevent new platform from introducing dummy stub function too. Initially, there are two APEI arch-specific calls: - arch_apei_enable_cmcff() - arch_apei_report_mem_error() Both interact with MCE driver for X86 architecture.
