From c26964ead57f0aa1dff4926aae2982b174798e7b Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 1 Oct 2009 15:41:06 +0100 Subject: wm831x: Factor out WM831x backup battery charger The backup battery on WM831x is a separate IP block to the main PMU and is largely unrelated to the main supply functionality. Factor it out into a separate driver in order to reflect this and better support future hardware versions.
