This patch support old and new pmic pca9451a. The new pmic trimed BUCK1. The default value of Toff_Deb is used to distinguish the old and new pmic. Signed-off-by: Joy Zou --- Changes in v2: 1. remove the old part support because the old part only is used for sample and is diffcult to distinguish old and new part. so drop old part. 2. remove the
