From 4a5d301328eb7cfb88f8164ddfd90c018b70ddc4 Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Fri, 21 Mar 2014 10:21:36 +0000 Subject: regulator: Add new driver for ST's PWM controlled voltage regulators On some STMicroelectronics hardware reside regulators consisting partly of a PWM input connected to the feedback loop. As the PWM duty-cycle is varied the output voltage adapts. This driver allows us to vary the output voltage by adapting the PWM input duty-cycle.
