+Subject: [PATCH] pmbus: add 'fault' and 'beep' attributes
+
+This commit adds two more attirbutes to reflect MFR_SPECIFIC bit in
+the STATUS_WORD and 'Unit Off For Insufficient Input Voltage' bit in
+the STATUS_INPUT into 'fault' and 'beep' attributes respectively.
+
+The attributes will be enumerated as 'inX_fault' and 'inX_beep' in
+a 'vin' group.
