watchdog: wdt-uclass.c: add wdt_stop_all() helper

2021-08-31T10:04:03Z

Since the watchdog_dev member of struct global_data is going away in favor of the wdt-uclass handling all watchdog devices, prepare for that by adding a helper to call wdt_stop() on all known devices. If an error is encountered, still do wdt_stop() on remaining devices, but remember and return the first error seen. Initially, this will only be used in one single place (board/alliedtelesis/x530/x530.c). Signed-off-by: Rasmus Villemoes

wdt: Drop dm.h header file

2020-08-04T02:19:54Z

This header file should not be included in other header files. Remove it and use a forward declaration instead. Also remove the other headers that are not needed, since the inline code was removed in a recent commit: b4d9452c4 ("watchdog: move initr_watchdog() to wdt-uclass.c") Signed-off-by: Simon Glass

common: Drop log.h from common header

watchdog: move initr_watchdog() to wdt-uclass.c

2020-04-15T06:53:55Z

This function is a bit large for an inline function, and for U-Boot proper, it is called via a function pointer anyway (in board_r.c), so cannot be inlined. It will shortly set a global variable to be used by the watchdog_reset() function in wdt-uclass.c, so this also allows making that variable local to wdt-uclass.c. The WATCHDOG_TIMEOUT_SECS define is not used elsewhere. Signed-off-by: Rasmus Villemoes Reviewed-by: Stefan Roese

watchdog: remove stale ifndef CONFIG_WATCHDOG_TIMEOUT_MSECS from wdt.h

2020-04-15T06:53:49Z

Since WATCHDOG_TIMEOUT_MSECS was converted to Kconfig (commit ca51ef7c0c), CONFIG_WATCHDOG_TIMEOUT_MSECS has been guaranteed to be defined. So remove the dead fallback ifdeffery. Signed-off-by: Rasmus Villemoes Reviewed-by: Stefan Roese

watchdog: Use dev_read only if OF_PLATDATA is not enabled

2020-03-16T10:25:12Z

Currently watchdog tries to use dev_read_u32_default to get timeout configuration in case OF_CONTROL is enabled. However, if SPL is built with OF_PLATDATA this has no sense as there is no device tree. This patch fixes this issue by only use dev_read_u32_default if OF_CONTROL is enabled but OF_PLATDATA is not.

watchdog: Split WDT from SPL_WDT

Use CONFIG_IS_ENABLED(WDT) to permit use of WDT in SPL without DM, while the full U-Boot can use rich DM/DT WDT driver. Signed-off-by: Marek Vasut Cc: Peng Fan Cc: Stefano Babic Tested-by: Heiko Schocher Tested-by: Suniel Mahesh

watchdog: Implement generic watchdog_reset() version

2019-04-26T07:16:32Z

This patch tries to implement a generic watchdog_reset() function that can be used by all boards that want to service the watchdog device in U-Boot. This watchdog servicing is enabled via CONFIG_WATCHDOG. Without this approach, new boards or platforms needed to implement a board specific version of this functionality, mostly copy'ing the same code over and over again into their board or platforms code base. With this new generic function, the scattered other functions are now removed to be replaced by the generic one. The new version also enables the configuration of the watchdog timeout via the DT "timeout-sec" property (if enabled via CONFIG_OF_CONTROL). This patch also adds a new flag to the GD flags, to flag that the watchdog is ready to use and adds the pointer to the watchdog device to the GD. This enables us to remove the global "watchdog_dev" variable, which was prone to cause problems because of its potentially very early use in watchdog_reset(), even before the BSS is cleared.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini
