| * watchdog: omap_wdt: early_enable module parameterLars Poeschel2015-07-011-0/+8
| | | | | | | | | | | | | | | | | | | | | | Add a early_enable module parameter to the omap_wdt that starts the watchdog on module insertion. The default value is 0 which does not start the watchdog - which also does not change the behavior if the parameter is not given.

| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, watchdog subsystem require the misc subsystem to register a watchdog. This may not be the case in case of an early registration of a watchdog, which can be required when the watchdog cannot be disabled.

| | | | | | | | | | | | | | | | | | | | | | | | This patch removes the static watchdog device for a new max63xx_wdt data structure, and constifies the max63xx_timeout data. The new structure contains pointers to pin access routines, which abstracts mmap-specific code. This will ease future accesses like GPIO.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you've got code that does this in a tight loop 1. Open watchdog 2. Send 'expect close' 3. Close watchdog ...you'll eventually trigger a watchdog reset. You can reproduce this by using daisydog (1) and running: while true; do daisydog -c > /dev/null; done The problem is that each time you write to the watchdog for 'expect close' it moves the timer .5 seconds out. The timer thus never fires and never pats the watchdog for you. 1: http://git.chromium.org/gitweb/?p=chromiumos/third_party/daisydog.git Signed-off-by: Doug Anderson <dianders@chromium.org> Tested-by: Jisheng Zhang <jszhang@marvell.com> Reviewed-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now the dw_wdt uses a spinlock to protect dw_wdt_open(). The problem is that while holding the spinlock we call: -> dw_wdt_set_top() -> dw_wdt_top_in_seconds() -> clk_get_rate() -> clk_prepare_lock() -> mutex_lock() Locking a mutex while holding a spinlock is not allowed and leads to warnings like "BUG: spinlock wrong CPU on CPU#1", among other problems. There's no reason to use a spinlock. Only dw_wdt_open() was protected and the test_and_set_bit() at the start of that function protects us anyway.

| * watchdog: omap: assert the counter being stopped before reprogrammingUwe Kleine-König2015-06-221-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The omap watchdog has the annoying behaviour that writes to most registers don't have any effect when the watchdog is already running. Quoting the AM335x reference manual: To modify the timer counter value (the WDT_WCRR register), prescaler ratio (the WDT_WCLR[4:2] PTV bit field), delay configuration value (the WDT_WDLY[31:0] DLY_VALUE bit field), or the load value (the WDT_WLDR[31:0] TIMER_LOAD bit field), the watchdog timer must be disabled by using the start/stop sequence (the WDT_WSPR register). Currently the timer is stopped in the .probe callback but still there are possibilities that yield to a situation where omap_wdt_start is entered with the timer running (e.g. when /dev/watchdog is closed without stopping and then reopened). In such a case programming the timeout silently fails! To circumvent this stop the timer before reprogramming. Assuming one of the first things the watchdog user does is setting the timeout explicitly nothing too bad should happen because this explicit setting works fine.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit add a driver for the watchdog functionality of the Conexant CX92755 SoC, from the Digicolor series of SoCs. Of 8 system timers provided by the CX92755, the first one, timer A, can reset the chip when its counter reaches zero. This driver uses this capability to provide userspace with a standard watchdog, using the watchdog timer driver core framework. This driver also implements a reboot handler for the reboot(2) system call. The watchdog driver shares the timer registers with the CX92755 timer driver (drivers/clocksource/timer-digicolor.c). The timer driver, however, uses only timers other than A, so both drivers should coexist.
