The flags that should be or-ed into the watchdog_info.options by drivers all start with WDIOF_, e.g. WDIOF_SETTIMEOUT, which indicates that the driver's watchdog_ops has a usable set_timeout. WDIOC_SETTIMEOUT was used instead, which expands to 0xc0045706, which equals: WDIOF_FANFAULT | WDIOF_EXTERN1 | WDIOF_PRETIMEOUT | WDIOF_ALARMONLY | WDIOF_MAGICCLOSE | 0xc0045000 These were so far indicated to userspace on WDIOC_GETSUPPORT. As the driver has not yet been migrated to the new watchdog kernel API, the constant can just be dropped without substitute.

The driver supports populating bootstatus with WDIOF_CARDRESET, but so far userspace couldn't portably determine whether absence of this flag meant no watchdog reset or no driver support. Or-in the bit to fix this. Fixes: b97cb21a ("watchdog: f71808e_wdt: Fix WDTMOUT_STS register read") Cc: stable@vger.kernel.org Signed-off-by:

The FIXME comment has been in-tree since the very first git commit. The described behavior has been since relied on by some userspace, e.g. the util-linux wdctl command and has been ignored by some kernelspace, like the f71808e_wdt driver. The functionality is useful to have to be able to differentiate between a driver that doesn't support WDIOF_CARDRESET and one that does, but hasn't had a watchdog reset, thus drop the FIXME to encourage drivers adopting this convention.

DW Watchdog can rise an interrupt in case if IRQ request mode is enabled and timer reaches the zero value. In this case the IRQ lane is left pending until either the next watchdog kick event (watchdog restart) or until the WDT_EOI register is read or the device/system reset. This interface can be used to implement the pre-timeout functionality optionally provided by the Linux kernel watchdog devices. IRQ mode provides a two stages timeout interface. It means the IRQ is raised when the counter reaches zero, while the system reset occurs only after subsequent timeout if the timer restart is not performed. Due to this peculiarity the pre-timeout value is actually set to the achieved hardware timeout, while the real watchdog timeout is considered to be twice as much of it. This applies a significant limitation on the pre-timeout values, so current implementation supports either zero value, which disables the pre-timeout events, or non-zero values, which imply the pre-timeout to be at least half of the current watchdog timeout. Note that we ask the interrupt controller to detect the rising-edge pre-timeout interrupts to prevent the high-level-IRQs flood, since if the pre-timeout happens, the IRQ lane will be left pending until it's cleared by the timer restart.

DW Watchdog IP core can be synthesised with asynchronous timer/APB clocks support (WDT_ASYNC_CLK_MODE_ENABLE == 1). In this case separate clock signals are supposed to be used to feed watchdog timer and APB interface of the device. Currently the driver supports the synchronous mode only. Since there is no way to determine which mode was actually activated for device from its registers, we have to rely on the platform device configuration data. If optional "pclk" clock source is supplied, we consider the device working in asynchronous mode, otherwise the driver falls back to the synchronous configuration. Signed-off-by:

In case if the DW Watchdog IP core is synthesised with WDT_USE_FIX_TOP == false, the TOP interval indexes make the device to load a custom periods to the counter. These periods are hardwired at the IP synthesis stage and can be within [2^8, 2^(WDT_CNT_WIDTH - 1)]. Alas their values can't be detected at runtime and must be somehow supplied to the driver so one could properly determine the watchdog timeout intervals. For this purpose we suggest to have a vendor- specific dts property "snps,watchdog-tops" utilized, which would provide an array of sixteen counter values. At device probe stage they will be used to initialize the watchdog device timeouts determined from the array values and current clocks source rate. In order to have custom TOP values supported the driver must be altered in the following way. First of all the fixed-top values ready-to-use array must be determined for compatibility with currently supported devices, which were synthesised with WDT_USE_FIX_TOP == true. It will be used if either fixed TOP feature is detected being enabled or no custom TOPs are fetched from the device dt node. Secondly at the probe stage we must initialize an array of the watchdog timeouts corresponding to the detected TOPs list and the reference clock rate. For generality the procedure of initialization is designed in a way to support the TOPs array with no limitations on the items order or value. Finally the watchdog period search methods should be altered to support the new timeouts data structure. Signed-off-by:

Modern device tree bindings are supposed to be created as YAML-files in accordance with dt-schema. This commit replaces the DW Watchdog legacy bare text bindings with YAML file. As before the binding states that the corresponding dts node is supposed to have a registers range, a watchdog timer references clock source, optional reset line and pre-timeout interrupt.
