From f447671b9e4fa4b0c9faf39455269d62d94218ae Mon Sep 17 00:00:00 2001 From: David Wu Date: Wed, 16 Mar 2016 02:45:26 +0800 Subject: PM / AVS: rockchip-io: add io selectors and supplies for rk3399 This adds the necessary data for handling io voltage domains on the rk3399. As interesting tidbit, the rk3399 contains two separate iodomain areas. One in the regular General Register Files (GRF) and one in PMUGRF in the pmu power domain.
