Subject: [PATCH 3/3] tty: serial: meson: Added S4 SOC compatibility
Date: Thu, 7 Apr 2022 16:13:55 +0800 [thread overview]
Message-ID: <20220407081355.13602-4-yu.tu@amlogic.com> (raw)
In-Reply-To: <20220407081355.13602-1-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.
