From 0f9520931eff906dab9c75a665fa0d4e59238166 Mon Sep 17 00:00:00 2001 From: Vince Hsu Date: Mon, 27 Apr 2015 11:48:02 +0800 Subject: [PATCH] drm/nouveau/volt/gk20a: share reusable members & functions The CVB calculation and voltage setting functions can be reused for the future chips. So move the declaration to gk20a.h.
