2015-06-22watchdog: dw_wdt: keepalive the watchdog at write timeDoug Anderson
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>
2015-06-22watchdog: dw_wdt: No need for a spinlockDoug Anderson
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.

2015-06-22watchdog: omap: assert the counter being stopped before reprogrammingUwe Kleine-König
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.

2015-06-22watchdog: digicolor: driver for Conexant Digicolor CX92755 SoCBaruch Siach
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.

If the cpu stays in snooze for more than target residency of the next available idle state, then exit from snooze.

Srinivas Pandruvada reported a problem with system resume from suspend-to-RAM on 32-bit x86 systems where the DS register of the CPU is set to __KERNEL_DS instead of __USER_DS on return to user space which cases a General Protection Fault to occur. The issue is that DS is set to __KERNEL_DS by the ACPI resume code path while the SYSEXIT path never reloads DS/ES. It assumes they are still __USER_DS set at the SYSENTER time (Brian Gerst), so if the return to user space happens to be through SYSEXIT, it will lead to the reported GPF. Fix the problem by setting the DS and ES registers to __USER_DS as expected by the SYSEXIT path.

2015-06-22PM / OPP: Add new bindings to address shortcomings of existing bindingsViresh Kumar
Current OPP (Operating performance point) device tree bindings have been insufficient due to the inflexible nature of the original bindings. Over time, we have realized that Operating Performance Point definitions and usage is varied depending on the SoC and a "single size (just frequency, voltage) fits all" model which the original bindings attempted and failed. The proposed next generation of the bindings addresses by providing a expandable binding for OPPs and introduces the following common shortcomings seen with the original bindings: - Getting clock/voltage/current rails sharing information between CPUs. Shared by all cores vs independent clock per core vs shared clock per cluster. - Support for specifying current levels along with voltages. - Support for multiple regulators. - Support for turbo modes. - Other per OPP settings: transition latencies, disabled status, etc.? - Expandability of OPPs in future. This patch introduces new bindings "operating-points-v2" to get these problems solved. Refer to the bindings for more details. We now have multiple versions of OPP binding and only one of them should be used per device.

This results problems on systems that have multiple PCHs (Platform Controller HUBs) because all of them also include their own copy of LPC device. All the subsequent device creations will fail because there already exists platform device with the same name. Fix this by passing PLATFORM_DEVID_AUTO as platform device id.

2015-06-22mfd: htc-i2cpld: Pass the IRQF_ONESHOT flagFabio Estevam
Since commit 1c6c69525b40eb76de8adf039409722015927dc3 ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request will fail. So pass the IRQF_ONESHOT flag in this case. The semantic patch that makes this change is available in scripts/coccinelle/misc/irqf_oneshot.cocci.
