No, sorry, that is not what I meant. set_timeout() should set ->timeout either to the requested value if equal to or larger than the maximum timeout supported by the hardware, and to the actually selected timeout otherwise.

From: Ludovic Barre <ludovic.barre@st.com> This patch series updates stm32 watchdog driver on: -use devm_watchdog_register_device -Guenter's recommendation about return value: set_timeout return 0 on succes, -EINVAL for "parameter out of range" and -EIO for "could not write value to the watchdog". Set of reload and prescaler registers are stay in start function, because the stm32 watchdog must be enabled to write these registers. -adds dynamic prescaler support Ludovic Barre (3): watchdog: stm32: update to devm_watchdog_register_device watchdog: stm32: update return values recommended by watchdog kernel api watchdog: stm32: add dynamic prescaler support drivers/watchdog/stm32_iwdg.c | 96 ++++++++++++++++++++++++------------------- 1 file changed, 54 insertions(+), 42 deletions(-)
