[Qemu-devel] [PATCH v1 1/1] sifive_u: Set 'clock-frequency' DT property for SiFive UART |
Date: |
Thu, 13 Dec 2018 18:36:17 +0000 |
From: Anup Patel <address@hidden>
The 'clock-frequency' DT property is required by U-Boot to compute
the divider value. This patch sets the 'clock-frequency' DT property
of the SiFive UART device tree node (similar to virt machine).
