Hi Wim, Gentle ping — both patches have been reviewed. Could this be queued for the next cycle? Thanks, Balakrishnan On 02/03/26 5:03 pm, Balakrishnan Sambath wrote:
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 Balakrishnan Sambath (2): watchdog: sama5d4_wdt: Fix WDDIS detection on SAM9X60 and SAMA7G5 watchdog: at91sam9_wdt.h: Document WDDIS bit position per SoC family drivers/watchdog/at91sam9_wdt.h | 6 +++-- drivers/watchdog/sama5d4_wdt.c | 48 +++++++++++++++------------------ 2 files changed, 25 insertions(+), 29 deletions(-)
