2016-03-16watchdog: atlas7_wdt: test clock rate to avoid division by 0Wolfram Sang
The clk API may return 0 on clk_get_rate, so we should check the result before using it as a divisor. Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
2016-03-16watchdog: s3c2410_wdt: Add max and min timeout valuesJavier Martinez Canillas
The watchdog maximum timeout value is determined by the number of bits for the interval timer counter, its source clock frequency, the number of bits of the prescaler and maximum divider value. This can be calculated with the following equation: max_timeout = counter / (freq / (max_prescale + 1) / max_divider) Setting a maximum timeout value will allow the watchdog core to refuse user-space calls to the WDIOC_SETTIMEOUT ioctl that sets not supported timeout values. For example, systemd tries to set a timeout of 10 minutes on reboot to ensure that the machine will be rebooted even if a reboot failed. This leads to the following error message on an Exynos5422 Odroid XU4 board: [ 147.986045] s3c2410-wdt 101d0000.watchdog: timeout 600 too big Reported-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Reviewed-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
2016-03-16Watchdog: introduce ARM SBSA watchdog driverFu Wei
According to Server Base System Architecture (SBSA) specification, the SBSA Generic Watchdog has two stage timeouts: the first signal (WS0) is for alerting the system by interrupt, the second one (WS1) is a real hardware reset. More details about the hardware specification of this device: ARM DEN0029B - Server Base System Architecture (SBSA) This driver can operate ARM SBSA Generic Watchdog as a single stage watchdog or a two stages watchdog, it's set up by the module parameter "action". In the single stage mode, when the timeout is reached, your system will be reset by WS1. The first signal (WS0) is ignored. In the two stages mode, when the timeout is reached, the first signal (WS0) will trigger panic. If the system is getting into trouble and cannot be reset by panic or restart properly by the kdump kernel(if supported), then the second stage (as long as the first stage) will be reached, system will be reset by WS1. This function can help administrator to backup the system context info by panic console output or kdump. This driver bases on linux kernel watchdog framework, so it can get timeout from module parameter and FDT at the driver init stage.

2016-03-16NVMe: Expose ns wwid through single sysfs entryKeith Busch
The method to uniquely identify a namespace depends on the controller's specification revision level and implemented capabilities. This patch has the driver figure this out and exports the unique string through a single 'wwid' attribute so the user doesn't have this burden. The longest namespace unique identifier is used if available. If not available, the driver will concat the controller's vendor, serial, and model with the namespace ID. The specification provides this as a unique indentifier.

2016-03-16mfd: as3711: Set regmap config reg counts properlyMaciej S. Szmigiero
Regmap config max_register field should contain number of device last register, however num_reg_defaults_raw field should be set to register count instead (usually one register more than max_register). as3711 driver had both of these fields set to the same value, fix this by introducing separate defines for max register number and total count of registers.

Add support for the TPS65086 PMIC GPOs. TPS65086 has four configurable GPOs that can be used for several purposes. These are output only. Signed-off-by: Andrew F. Davis <afd@ti.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2016-03-16mfd: mt6397: Add platform device ID tableJavier Martinez Canillas
The platform bus_type .match callback attempts to match the platform device name with an entry on the .id_table if provided and fallbacks to match with the driver's name if a table is not provided. Using a platform device ID to match is more explicit, allows the driver to support more than one device and also the MODULE_DEVICE_TABLE macro can be used to export the module aliases information instead of the MODULE_ALIAS.

2016-03-16mfd: da9063: Fix missing volatile registers in the core regmap_range ↵Steve Twiss
volatile lists Add an updated set of registers listed in the core regmap_range volatile ranges defined for the DA9063. These new registers contain bits that cannot be considered under the full control of software. Under various conditions the hardware will set and/or automatically clear bit(s) contained in these registers. When using a cached version of regmap, the volatility of these registers must be identified otherwise the regmap operations may not ensure the registers are explicitly altered. As well as updating the list of volatile registers, this change will fix a corner case discovered in the DA9063 ONKEY which is used by the DA9063 core. In the ONKEY case, the CONTROL_B register is now listed as volatile in the regmap_range because it contains the bit field NONKEY_LOCK. This bit can be altered by hardware, in which case regmap must be notified of its ability to be manpiulated outside of software control.
