From 7424e95a693d01a93e3e037553a31e42cb422323 Mon Sep 17 00:00:00 2001 From: Rick Chen Date: Tue, 13 Nov 2018 15:13:34 +0800 Subject: [PATCH] riscv: dts: Sync to Linux Kernel ae350 dts. Use same dts to boot U-Boot and Kernel. Following are the change notes : 1 Remove early printk bootargs. 2 Timer frequency are changed to 60MHz. 3 Add dma, snd, lcd, virtio nodes which are used in kernel drivers. They does not been used by U-Boot. 4 Change spi irq from 3 to 4.
