+
+This commit introduces support for NETGEAR ReadyNAS Duo v2.
+This device use bit 4 of LED[2:0] Polarity Control Register to indicate
+AC Power loss.
+
+For more details about AC loss detection in NETGEAR ReadyNAS Duo v2,
+please look at the file:
+RND_5.3.13_WW.src/u-boot/board/mv_feroceon/mv_hal/usibootup/usibootup.c
+from Netgear GPL sources.

+Subject: [PATCH 2/2] power: reset: linkstation-poweroff: add new device
+
+This commit introduces support for NETGEAR ReadyNAS Duo v2.
+This device use bit 4 of LED[2:0] Polarity Control Register to indicate
+AC Power loss.
+
+For more details about AC loss detection in NETGEAR ReadyNAS Duo v2,
+please look at the file:
+RND_5.3.13_WW.src/u-boot/board/mv_feroceon/mv_hal/usibootup/usibootup.c
+from Netgear GPL sources.
