From 4fa949d36bfe645515b1d2d05f61ebad65a3070a Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Wed, 30 Sep 2015 21:00:16 +0200 Subject: [PATCH 3/5] ARM: dts: rockchip: add rk3288-popmetal iodomains Add the iodomains node and reference the correct regulator for each domain. This also includes adding the currently unused dvp regulators and fixing up two regulators to follow the naming in the schematics.
