From fad486ce51b7ae96f5004e50249c675d5ac20136 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 7 Feb 2015 11:51:47 -0700 Subject: [PATCH] powerpc: Add serial driver for driver model This uses the ns16550 driver but sets up the clock at run-time. It does not seem to be available in the device tree.
