From adfe3b76608ffe547af5a74415f15499b798f32a Mon Sep 17 00:00:00 2001 From: Enric Balletbo i Serra Date: Thu, 21 Mar 2019 19:14:36 -0400 Subject: PM / devfreq: rockchip-dfi: Move GRF definitions to a common place. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Some rk3399 GRF (Generic Register Files) definitions can be used for different drivers. Move these definitions to a common include so we don't need to duplicate these definitions.
