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.
V5->V6:
- Replace hard-coded 0x8000 with calculated value.
- Link to v5:
https://lore.kernel.org/linux-watchdog/20250806065514.3688485-1-sw617.shin@xxxxxxxxxxx/
V4->V5:
- Update s3c2410wdt_max_timeout with Sam Protsenko and Guenter Roeck's sugestion.
- Break [v4 3/4] into two [v5 3/5] and [v5 4/5].
- Rename S3C2410_WTCNT_MAXCNT to S3C2410_WTCNT_MAXCNT_16.
- Rename QUIRK_HAS_32BIT_MAXCNT to QUIRK_HAS_32BIT_CNT.
- Minor Typographical Errors and Style Adjustments.
- Link to v4:
https://lore.kernel.org/linux-watchdog/20250724080854.3866566-1-sw617.shin@xxxxxxxxxxx/
V3->V4:
- Merge patches [v3 3/5] and [v3 4/5] into one so that Quirk and its consumer
are part of the same patch.
- Link to v3:
https://lore.kernel.org/linux-watchdog/20250714055440.3138135-1-sw617.shin@xxxxxxxxxxx/
https://lore.kernel.org/linux-watchdog/20250515075350.3368635-1-sw617.shin@xxxxxxxxxxx/
V2->V3:
- Correct the incorrect tag information.
- Link to v2:
https://lore.kernel.org/linux-watchdog/20250514094220.1561378-1-sw617.shin@xxxxxxxxxxx/
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
