Subject: [PATCH V2 2/2] tty: serial: meson: Added S4 SOC compatibility
Date: Mon, 18 Apr 2022 13:32:02 +0800 [thread overview]
Message-ID: <20220418053202.24528-3-yu.tu@amlogic.com> (raw)
In-Reply-To: <20220418053202.24528-1-yu.tu@amlogic.com>
Make UART driver compatible with S4 SOC UART. Meanwhile, the S4 SOC
UART uses 12MHz as the clock source for baud rate calculations.
