When the starfive watchdog driver uses 'pm_runtime_put_sync()' as probe return value at last and 'early_enable' is disabled, it could return the error '-ENOSYS' if the CONFIG_PM is disabled, but the driver should works normally. Drop the 'return' and keep the 'pm_runtime_put_sync()', but do not use it as the return value. Fixes: db728ea9 ("drivers: watchdog: Add StarFive Watchdog driver") Signed-off-by:

When setting the timeout for the menz069_wdt watchdog driver, we erroneously read from the 'watchdog value register' (WVR) instead of the 'watchdog timer register' (WTR) and then write the value back into WTR. This can potentially lead to wrong timeouts and wrong enable bit settings. Signed-off-by:

Doing a 'cat /dev/watchdog0' with menz069_wdt as watchdog0 will result in a NULL pointer dereference. This happens because we're passing the wrong pointer to watchdog_register_device(). Fix this by getting rid of the static watchdog_device structure and use the one embedded into the driver's per-instance private data. Signed-off-by:

Two conversions to DT schema of GPIO watchdog binding happened and came through different trees. Merge them into one: 1. Combine maintainers, 2. Use more descriptive property descriptions and constraints from gpio-wdt.yaml, 3. Switch to unevaluatedProperties:false, to allow generic watchdog properties. Signed-off-by:

If potentially no valid element is found, 'p' would contain an invalid pointer past the iterator loop. To ensure 'p' is valid under any circumstances, the kfree() should be within the loop body. Additionally, Linus proposed to avoid any use of the list iterator variable after the loop, in the attempt to move the list iterator variable declaration into the macro to avoid any potential misuse after the loop [1].

The watchdog countdown is supposed to begin when the device file is opened. Instead, it would begin countdown upon the first write to or close of the device file. Now, the ping operation is called within the start operation which ensures the countdown begins. From experimenation, it does not appear possible to do this with a single write including both the start bit and the trigger bit. So, it is done as two distinct writes. Signed-off-by:

Ralink RT2880 Watchdog bindings used text format, so migrate them to YAML. There are some additions to the binding that were not in the original txt file. This binding is used in RT2880, RT3050, RT3352, RT3883, RT5350, and MT7620 SoCs. To properly align binding with driver code we need to add to the schema 'clocks' and 'resets' properties.

Make use of dev_err_probe() also for error paths that don't have to handle -EPROBE_DEFER. While the code handing -EPROBE_DEFER isn't used for these error paths, it still simpler as it cares for pretty printing the error code and usually needs one code line less as it combines message emitting and error returning. This also unifies the format of the error messages. Signed-off-by:

This is a preparation for making more use of dev_err_probe(). The idea is that s3c2410_get_wdt_drv_data() (as it's called only by .probe()) can make effective use of dev_err_probe() only if it returns an int. For that the assignment to wdt->drv_data has to happen in the function. The caller can then just pass on the return value in the error case. This seems to be nicer for the compiler: bloatometer reports for an ARCH=arm s3c6400_defconfig build: add/remove: 1/1 grow/shrink: 0/1 up/down: 4/-64 (-60) Function old new delta __initcall__kmod_s3c2410_wdt__209_821_s3c2410wdt_driver_init6 - 4 +4 __initcall__kmod_s3c2410_wdt__209_819_s3c2410wdt_driver_init6 4 - -4 s3c2410wdt_probe 1332 1272 -60 There is no semantical change. (Just one minor difference: Before this patch wdt->drv_data was always assigned, now that only happens in the non-error case. That doesn't matter however as *wdt is freed in the error case.)

If the sbsa_gwdt is enabled by BIOS, the kernel set WDOG_HW_RUNNING bit and keep it alive before anyone else would open it. When system suspend, the sbsa_gwdt would not be disabled because WDOG_ACTIVE is not set. Then the sbsa_gwdt would reach timeout since no one touch it during system suspend. To solve this, just test WDOG_HW_RUNNING bit in suspend and disable the sbsa_gwdt if the bit is set, then reopen it accordingly in resume process. Signed-off-by:

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:
