From b75e9e3fce8d8fa2ca45e12032fae57240821f65 Mon Sep 17 00:00:00 2001 From: Pascal Linder Date: Tue, 9 Jul 2019 09:30:26 +0200 Subject: [PATCH] km/uart: port UART interface of KM Kirkwood boards to driver model Activate the driver model for the serial interface in the KM Kirkwood Kconfig file. The associated preprocessor definitions could be removed from the header file. However, the clock of 200 MHz needs to be declared in the device tree.
