From 96f3f1f905e9c4977220fa07477cd8a8ed4af4da Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Mon, 6 Jul 2015 15:10:02 +0300 Subject: [PATCH] drm/i915: Don't pass clock to DDI PLL select functions MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit All the *_ddi_pll_select() functions get passed the port_clock and pipe config as parameters. We only need to pass the pipe config, and the functions can dig up the port_clock themselves.
