2016-03-16watchdog: Introduce WDOG_HW_RUNNING flagGuenter Roeck1-13/+39
The WDOG_HW_RUNNING flag is expected to be set by watchdog drivers if the hardware watchdog is running. If the flag is set, the watchdog subsystem will ping the watchdog even if the watchdog device is closed. The watchdog driver stop function is now optional and may be omitted if the watchdog can not be stopped. If stopping the watchdog is not possible but the driver implements a stop function, it is responsible to set the WDOG_HW_RUNNING flag in its stop function.

2016-03-16watchdog: Introduce hardware maximum heartbeat in watchdog coreGuenter Roeck1-8/+121
Introduce an optional hardware maximum heartbeat in the watchdog core. The hardware maximum heartbeat can be lower than the maximum timeout. Drivers can set the maximum hardware heartbeat value in the watchdog data structure. If the configured timeout exceeds the maximum hardware heartbeat, the watchdog core enables a timer function to assist sending keepalive requests to the watchdog driver.

2016-03-16watchdog: Make set_timeout function optionalGuenter Roeck1-2/+9
For some watchdogs, the watchdog driver handles timeout changes without explicitly setting any registers. In this situation, the watchdog driver might only set the 'timeout' variable but do nothing else. This can as well be handled by the infrastructure, so make the set_timeout callback optional. If WDIOF_SETTIMEOUT is configured but the .set_timeout callback is not available, update the timeout variable in the infrastructure code.

2016-03-16watchdog: s3c2410_wdt: Add max and min timeout valuesJavier Martinez Canillas1-0/+16
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 <[email protected]> Signed-off-by: Javier Martinez Canillas <[email protected]> Reviewed-by: Krzysztof Kozlowski <[email protected]> Signed-off-by: Guenter Roeck <[email protected]> Signed-off-by: Wim Van Sebroeck <[email protected]>
2016-03-16Watchdog: introduce ARM SBSA watchdog driverFu Wei3-0/+429
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.

2016-03-16mfd: ipaq-micro: Use __maybe_unused to hide pm functionsArnd Bergmann1-1/+1
The ipaq-micro driver uses SET_SYSTEM_SLEEP_PM_OPS() to remove the reference to its resume function, but does not use an #ifdef around the definition, so we get a build warning: drivers/mfd/ipaq-micro.c:379:12: error: 'micro_resume' defined but not used [-Werror=unused-function] This adds a __maybe_unused annotation so the compiler knows it can silently drop it instead of warning.

2016-03-16mfd: max77686: Add max77802 to I2C device ID tableJavier Martinez Canillas1-0/+1
The max77686 MFD driver supports both the Maxim 77686 and Maxim 77802 PMICs but only the OF device table contains entries for both devices. The max77802 entry is missing in the I2C device ID table which isn't a problem currently since the driver only supports DT but it will be needed if the driver is changed to be built as a module since the I2C core always reports a I2C modalias uevent so auto-load will not work.

2016-03-16mfd: max77686: Export OF module alias informationJavier Martinez Canillas1-0/+1
When the device is registered via OF, the OF table is used to match the driver instead of the I2C device ID table but the entries in the latter are used as aliasses to load the module if the driver was not built-in. This is because the I2C core always reports an I2C module alias instead of an OF one but that could change so it is better to always export it.

2016-03-16mfd: max77686: Allow driver to be built as a moduleJavier Martinez Canillas1-2/+2
The driver's Kconfig symbol is a boolean but nothing prevents the driver to be built as a module instead of built-in. It is true that most system integrators will choose the latter but the config should not restrict it.

2016-03-16mfd: stmpe: Add the proper PWM resourcesLinus Walleij1-0/+35
This adds the PWM resources to the STMPE MFD driver, so that it can properly grab and use them. Signed-off-by: Linus Walleij <[email protected]> Signed-off-by: Lee Jones <[email protected]>
2016-03-16mfd: tps65090: Set regmap config reg counts properlyMaciej S. Szmigiero1-3/+2
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). tps65090 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.
