From 543853de356b8ce95d6d99757501d9d5c916ca09 Mon Sep 17 00:00:00 2001 From: Matthias Kaehlcke Date: Tue, 16 May 2017 11:43:42 -0700 Subject: [PATCH] regulator: DT: Add properties for asymmetric settling times Some regulators have different settling times for voltage increases and decreases. Add DT properties to define separate settling times for up- and downward voltage changes.
