watchdog: renesas_wwdt: Convert to common field_{get, prep}() helpers

2026-07-08T19:29:18Z

Drop the driver-specific field_get() and field_prep() macros, in favor of the globally available variants from . Signed-off-by: Mikhail Kshevetskiy Reviewed-by: Simon Glass

watchdog: renesas_wwdt: #undef field_{get, prep}() before definition

2026-07-08T19:29:17Z

Prepare for the advent of globally available common field_get() and field_prep() macros by undefining the symbols before defining local variants. This prevents redefinition warnings from the C preprocessor when introducing the common macros later. Signed-off-by: Mikhail Kshevetskiy

drivers: watchdog: Fix dev_read_addr error check

2026-06-09T09:51:19Z

dev_read_addr does not return a void* but fdt_addr_t. Replace invalid usage of dev_read_addr by dev_read_addr_ptr. v2: - Replace dev_read_addr by dev_read_addr_ptr - Change error to EINVAL Signed-off-by: Francois Berder Reviewed-by: Stefan Roese Reviewed-by: Hal Feng

watchdog: mpc8xxx_wdt: Use dev_remap_addr()

2026-06-09T09:51:19Z

Use dev_remap_addr() to replace devfdt_remap_addr which supports both live device tree and flat DT backends, avoiding direct dependency on devfdt_* helpers. No functional changes. Signed-off-by: Peng Fan Reviewed-by: Stefan Roese

watchdog: rti: Use dev_read_addr_ptr()

2026-06-09T09:51:19Z

devfdt_get_addr() returns FDT_ADDR_T_NONE(-1UL) when fail, using "!priv->regs" to check return value is wrong. Replace devfdt_read_addr() with dev_read_addr_ptr() when retrieving the register base address. dev_read_addr_ptr() supports both live device tree and flat DT backends, avoiding direct dependency on devfdt_* helpers. Also use "void __iomem *" to replace "phys_addr_t" to avoid type casting. No functional changes. Signed-off-by: Peng Fan Reviewed-by: Stefan Roese

watchdog: octeontx_wdt: fix DT matches to Marvell compatibles

2026-06-09T09:51:19Z

The OcteonTX watchdog driver currently matches arm,sbsa-gwdt. On systems with multiple watchdog devices this can be ambiguous since arm,sbsa-gwdt is a generic SBSA binding. Replace the SBSA match with SoC-specific Marvell compatibles marvell,cn10624-wdt and marvell,cn9670-wdt. These compatibles align with the upstream Linux device tree binding: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/watchdog/marvell,cn10624-wdt.yaml Reviewed-by: Aaro Koskinen Signed-off-by: Juuso Rinta Reviewed-by: Stefan Roese

watchdog: sbsa_gwdt: clamp WOR value to hw max

2026-06-09T09:51:19Z

The WOR register is 32 bits, so any tick count exceeding U32_MAX is truncated by writel(). A large requested timeout can wrap to a small value causing the watchdog to fire sooner than requested. Clamp the calculated value to U32_MAX prior to writing the register so over-large requests will be set to the maximum timeout value. Found by code review.

watchdog: designware: Fix probe when clk_enable return ENOSYS

2026-06-09T09:51:19Z

Rockchip SoCs typically reset with all (or most) clocks ungated. Because of this, U-Boot clock drivers for Rockchip typically do not implement the optional clk-uclass enable/disable ops. Normal driver model behavior is to return -ENOSYS when an uclass ops is not implemented. Ignore -ENOSYS to allow the designware watchdog driver to be probed on platforms that do not implement the clk-uclass enable/disable ops, e.g. Rockchip RK3308. Signed-off-by: Jonas Karlman
