* power/reset: restart-poweroff: Remove arm dependenciesGuenter Roeck2015-01-252-2/+0
| | | | | | | | | This driver is now arm specific anymore, so there is no need to include an arm specific include file. Also drop unnecessary depencency on ARM from Kconfig. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Sebastian Reichel <sre@kernel.org>
* power/reset: st-poweroff: Fix misleading Kconfig descriptionGuenter Roeck2015-01-251-2/+2
| | | | | | | | | The st-poweroff driver does not really power off the system but resets it, so Kconfig should not claim that the driver would handle power-off. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Sebastian Reichel <sre@kernel.org>

* power/reset: at91-poweroff: Fix error handling and other compiler warningsGuenter Roeck2015-01-211-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | at91_poweroff_get_wakeup_mode can return a negative error code and should therefore not return an enum type. Similar, its result should not be assigned to an enum type. Otherwise, the returned value is never negative, resulting in a compiler warning and a missed error condition, which in turn results in writing bad values into a chip register. Also fix other compiler warnings which can be easily avoided. drivers/power/reset/at91-poweroff.c:74:24: warning: type qualifiers ignored on function return type drivers/power/reset/at91-poweroff.c:74:24: warning: no previous prototype for 'at91_poweroff_get_wakeup_mode' drivers/power/reset/at91-poweroff.c:83:16: warning: comparison between signed and unsigned integer expressions drivers/power/reset/at91-poweroff.c:97:2: warning: comparison of unsigned expression < 0 is always false Cc: Maxime Ripard <maxime.ripard@free-electrons.com> Cc: Nicolas Ferre <nicolas.ferre@atmel.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Sebastian Reichel <sre@kernel.org>
* power: reset: Add reset driver for R-Mobile platformsGeert Uytterhoeven2015-01-213-0/+98
| | | | | | | | | | | | | | | | | Add a reset driver for Renesas R-Mobile and SH-Mobile SoCs. It registers a restart handler to trigger a soft power-on reset through the R-Mobile System Controller. The priority of this restart handler is 192, to allow a watchdog driver to use priority 128. Note that we do not use syscon-reboot, as the HPB (Peripheral Bus Bridge) semaphore should be acquired on systems where both the ARM and SH core are in use. The driver can be extended later to support this, when needed.

* power: reset: ltc2952: make trigger input optionalFrans Klaver2015-01-201-32/+55
| | | | | | | | | | | | | | | | | Currently the ltc2952 supports only one button sequence to initiate powerdown. This is not always desirable, as even prolonged button presses can happen in use. Allow ltc2952 users to pick their own power down sequence, by making the trigger input optional. Since this still means that the ltc2952 may power down the platform if the power button is pressed for about 5 seconds, we still need to make sure to start the watchdog toggle to prolong the system power for as long as we need it. This will still allow the system to control power using the kill signal. Signed-off-by: Frans Klaver <frans.klaver@xsens.com> Signed-off-by: Sebastian Reichel <sre@kernel.org>
* power: reset: ltc2952: check trigger value before starting timerFrans Klaver2015-01-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In ltc2952_poweroff_handler it is theoretically possible that the timer fails to start on first pass (button press), but succeeds in starting on the second (button release). This will cause the button press to be misinterpreted, and will incorrectly shut down the system. Because a picture says more than a thousand words: Expected behavior: tmr: ++++++++++ btn: -----__________----- Faulty behavior: tmr: +++++ btn: -----__________----- Legend: + timer runs _ button pressed - button depressed To prevent this from happening, check the value of the gpio before starting the timer. If the button is active, we should start the timer, else we should stop it. The situation described can now still occur if the polarity of the input pin is set incorrectly, but that at least is predictable behavior and can be detected during the first tests.

| | | | | | | | | | | ltc2952_poweroff_handler uses gotos to return from the function. Since we don't do cleanups exiting this function, just return IRQ_HANDLED on the spot and be done with it.

* power: reset: ltc2952: drop empty suspend/resume functionsFrans Klaver2015-01-201-13/+0
| | | | | | | | | | | | Documentation/SubmittingDrivers suggests these be implemented even when they do nothing. On the other hand, the platform code calls these functions 'legacy'. Suspend and resume operations should go into a pm_ops structure, pointed at by the driver's pm field. This approach would lead to a lot of boiler plate, while achieving nothing. Drop the functions instead. Signed-off-by: Frans Klaver <frans.klaver@xsens.com> Signed-off-by: Sebastian Reichel <sre@kernel.org>
* power: reset: ltc2952: remove global variable poweroff_panicFrans Klaver2015-01-201-35/+22
| | | | | | | | | | | | As per Documentation/CodingStyle ch.4, we should keep global variables to a mininum. Move the panic state into the driver data, regardless of whether panic is a system state or not. This removes the need for the custom _init and _exit functions, so replace them with a call to the module_platform_driver() macro.

Reduce the use of the global instance of ltc2952_poweroff so we may eventually remove it entirely. While at it, rename ltc2952_poweroff_data to ltc2952_poweroff, just to save that little bit of typing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, all restart handler use the priority 128, including watchdogs. Probably most SoC have a watchdog, and some of them register it also as a restart handler. But if a SoC specifies a dedicated reboot capability using this syscon driver, this is usually the preferred reboot method. Hence, raise the priority of this driver to 192.

| * power: reset: corrections for simple syscon reboot driverFeng Kan2014-10-032-17/+13
| | | | | | | | | | | | | | | | | | | | | | This patch is to fix some bugs in reboot driver. Which includes auto selection of the MFD_SYSCON for the driver, use of container to locate restart handler, correction of the count down failure timer and ordering of the header file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change replaces use of arm_pm_restart with recently introduced reset mechanism in Linux kernel called restart_notifier. Choosing priority 128, which is default priority, as according to documentation, this mechanism is sufficient to restart the entire system.
