From 5ba55fa81aee9493928c245f142a0bfe9f32d02f Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 30 Apr 2014 02:31:46 +0200 Subject: [PATCH] ARM: shmobile: koelsch: Enable SCIF0 and SCIF1 serial ports in DT SCIF0 and SCIF1 are used as debug serial ports. Enable them and configure pinmuxing appropriately. We can now remove the clkdev registration hack for SCIF devices from the Koelsch reference board file.
