The STM32MP15xx IWDG adds registers which permit this IP to generate
pretimeout interrupt. This interrupt can also be used to wake the CPU
from suspend. Implement support for generating this interrupt and let
userspace configure the pretimeout. In case the pretimeout is not
configured by user, set pretimeout to 3/4 of the WDT timeout cycle.

V2: - Subtract the pretimeout value from timeout value before writing it
       into the IWDG pretimeout register, because the watchdog counter
       register is counting down, and the pretimeout interrupt triggers
       when watchdog counter register matches the pretimeout register
       content.
     - Set default pretimeout to 3/4 of timeout .
V3: - Use dev instead of pdev->dev
     - Swap order of ret/return 0
     - Split this from the DT changes, which are orthogonal
     - Uh, this patch got stuck in upstreaming queue, sorry
V4: - Update commit message to match V2 default pretimeout to 3/4
     - Add RB/TB from Clément

Hi,

Are there still any open topics with this patch ?

Anything ?

Can this be pulled via the stm32 SoC tree ?
