Subject: [PATCH 2/6] rtc: m41t80: Rename FEATURE_WD to FEATURE_WDR for clarity
Date: Wed,  1 Apr 2026 19:52:41 +0300	[thread overview]
Message-ID: <20260401165245.936428-2-eagle.alexander923@gmail.com> (raw)
In-Reply-To: <20260401165245.936428-1-eagle.alexander923@gmail.com>

The FEATURE_WD flag indicates extra watchdog resolution support.
Rename it to FEATURE_WDR to better reflect its purpose
(WatchDog Resolution). No functional change.
