From 7d3aa342cef7aa3721bab5157a84bb3d6acce437 Mon Sep 17 00:00:00 2001 From: Radu Pirea Date: Fri, 13 Jul 2018 19:47:33 +0300 Subject: mfd: at91-usart: Add MFD driver for USART This MFD driver is just a wrapper over atmel_serial driver and spi-at91-usart driver. Selection of one of the drivers is based on a property from device tree. If the property is not specified, the default driver is atmel_serial.
