Subject: [PATCH 0/3] tty: serial: meson: add amlogic,uart-fifosize property
Date: Mon, 15 Mar 2021 09:34:56 +0100 [thread overview]
Message-ID: <20210315083459.359773-1-narmstrong@baylibre.com> (raw)
On most of the Amlogic SoCs, the first UART controller in the "Everything-Else"
power domain has 128bytes of RX & TX FIFO, so add an optional property to describe
a different FIFO size from the other ports (64bytes).
This adds a property in the bindings, reads the property from the driver and updates
the DT with the new property.
Neil Armstrong (3):
dt-bindings: serial: amlogic,meson-uart: add amlogic,uart-fifosize
property
tty: serial: meson: retrieve port FIFO size from DT
arm64: dts: meson: set 128bytes FIFO size on uart A
