From c6182ac96096f35c7216e4e6a3c64c7374dadeb7 Mon Sep 17 00:00:00 2001 From: George McCollister Date: Thu, 9 Mar 2017 08:14:43 -0600 Subject: regulator: pfuze100-regulator: add coin support Add support for PF0200 coin cell/super capacitor charger which works as a current limited voltage source via the LICELL pin. When VIN goes below a certain threshold LICELL is used to provide power for VSNVS which is usually used to hold up secure non-volatile storage and the real-time clock on the SoC.
