Synopsys DesignWare APB UART is seen on the StarFive JH7100 SoC. Its programming interface is compatible with the existing 8250 UART driver. Simply add its compatible string to the driver makes it work with the StarFive JH7100 SoC on a BeagleV board. With this patch, the generic platform firmware can be used out of the box on the BeagleV board. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Anup Patel <anup.patel@wdc.com>
