-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.
