watchdog: rti_wdt: Fix an OF node leak in rti_wdt_probe()

2025-02-08T09:02:02+00:00

[ Upstream commit 143981aa63f33d469a55a55fd9fb81cd90109672 ] rti_wdt_probe() does not release the OF node reference obtained by of_parse_phandle(). Add a of_node_put() call. This was found by an experimental verification tool that I am developing. Due to the lack of the actual device, no runtime test was able to be performed.

watchdog: stm32_iwdg: fix error message during driver probe

2024-12-30T14:28:02+00:00

The commit 3ab1663af6c1 ("watchdog: stm32_iwdg: Add pretimeout support") introduces the support for the pre-timeout interrupt. The support for this interrupt is optional but the driver uses the platform_get_irq() which produces an error message during the driver probe if we don't have any `interrupts` property in the DT. Use the platform_get_irq_optional() API to get rid of the error message as this property is optional.

module: Convert symbol namespace to string literal

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

Get rid of 'remove_new' relic from platform driver struct

2024-12-01T23:12:43+00:00

The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds

watchdog: rti: of: honor timeout-sec property

2024-11-17T10:24:22+00:00

Currently "timeout-sec" Device Tree property is being silently ignored: even though watchdog_init_timeout() is being used, the driver always passes "heartbeat" == DEFAULT_HEARTBEAT == 60 as argument. Fix this by setting struct watchdog_device::timeout to DEFAULT_HEARTBEAT and passing real module parameter value to watchdog_init_timeout() (which may now be 0 if not specified).

Adds the compatibles and drvdata for the ExynosAuto V920 SoC. This SoC is almost similar to ExynosAutoV9, but some CPU configurations are quite different, so it should be added. Plus it also support DBGACK like as GS101 SoC.
