[PATCH v2 0/5] Increase max timeout value of s3c2410 watchdog

[Sangwook Shin]

The ExynosAutoV9 and ExynosAutoV920 SoCs have a 32-bit counter register,
but due to code constraints, only 16-bit values could be used.
This series enables these SoCs to use the 32-bit counter.
Additionally, it addresses the issue where the ExynosAutoV9 SoC supports
the DBGACK bit but it was not set.

V1->V2:
  - Modify the max_timeout calculation considering overflow
  - Separate tha max_timeout calculation into a separate patch
  - Add max_cnt in struct s3c2410_wdt
  - Set max_cnt once in probe function
  - Add patch that uses S3C2410_WTCON_PRESCALE_MAX instead of hardcoded one
  - Remove unnecessary inner parentheses
  - Link to v1:
