From 4dcdcfd5abb34d3139669fcd830b756d45678c47 Mon Sep 17 00:00:00 2001 From: Matti Vaittinen Date: Mon, 5 Apr 2021 14:42:51 +0300 Subject: mfd: Support for ROHM BD71815 PMIC core Add core support for ROHM BD71815 Power Management IC. The IC integrates regulators, a battery charger with a coulomb counter, a real-time clock (RTC), clock gate and general-purpose outputs (GPO).
