Subject: [PATCH v8 02/22] riscv: Fix sifive serial driver
Date: Thu, 10 Dec 2020 23:02:53 +0900	[thread overview]
Message-ID: <20201210140313.258739-3-damien.lemoal@wdc.com> (raw)
In-Reply-To: <20201210140313.258739-1-damien.lemoal@wdc.com>

Setup the port uartclk in sifive_serial_probe() so that the base baud
rate is correctly printed during device probe instead of always showing
"0".  I.e. the probe message is changed from

38000000.serial: ttySIF0 at MMIO 0x38000000 (irq = 1,
base_baud = 0) is a SiFive UART v0

to the correct:

38000000.serial: ttySIF0 at MMIO 0x38000000 (irq = 1,
base_baud = 115200) is a SiFive UART v0
