From 4c2808fd06c3f75df302af6a1354f3ec12278980 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Richard=20R=C3=B6jfors?= Date: Wed, 14 Nov 2018 14:13:53 +0100 Subject: [PATCH] rockchip: video: mipi: Fix phy frequency setting MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit There was an incorrect check when looping and finding the first fast enough frequency in the freq_rang table. The code did actually return the first that was either exactly correct or too slow.
