Subject: [PATCH AUTOSEL 5.4 08/26] riscv: Fix sifive serial driver
Date: Tue, 19 Jan 2021 20:26:45 -0500 [thread overview]
Message-ID: <20210120012704.770095-8-sashal@kernel.org> (raw)
In-Reply-To: <20210120012704.770095-1-sashal@kernel.org>
From: Damien Le Moal <damien.lemoal@wdc.com>
[ Upstream commit 1f1496a923b6ba16679074fe77100e1b53cdb880 ]
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
