Subject: [PATCH 1/3] dt-bindings: serial: amlogic, meson-uart: add fifo-size property
Date: Tue, 18 May 2021 09:58:31 +0200 [thread overview]
Message-ID: <20210518075833.3736038-2-narmstrong@baylibre.com> (raw)
In-Reply-To: <20210518075833.3736038-1-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).
