Re: [PATCH v2 0/2] watchdog: sama5d4_wdt: Fix WDDIS handling for SAM9X60 and SAMA7G5

Hi Wim,

Gentle ping — both patches have been reviewed. Could this be queued for 
the next cycle?

Thanks,
Balakrishnan

The sama5d4_wdt driver hardcodes AT91_WDT_WDDIS (bit 15) for WDDIS
detection, which is incorrect for SAM9X60 and SAMA7G5 that use bit 12
(AT91_SAM9X60_WDDIS). This series fixes the detection by introducing
a per-device wddis_mask and documents the bit position difference in
the header.

Changes in v2:
- Reorder patches: fix first, documentation second
- Drop patch 3/3, not needed with wddis_mask approach
- Keep AT91_SAM9X60_* register names, drop _LEGACY/_MODERN naming
- Limit header changes to WDDIS comments and datasheet references
