Subject: [PATCH v2 1/3] dt-bindings: serial: amlogic,meson-uart: add fifo-size property
Date: Thu, 25 Mar 2021 16:24:08 +0100	[thread overview]
Message-ID: <20210325152410.1795557-2-narmstrong@baylibre.com> (raw)
In-Reply-To: <20210325152410.1795557-1-narmstrong@baylibre.com>

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).
