Subject: [PATCH AUTOSEL 5.5 354/542] MIPS: ralink: dts: gardena_smart_gateway_mt7688: Limit UART1
Date: Fri, 14 Feb 2020 10:45:46 -0500
Message-ID: <20200214154854.6746-354-sashal@kernel.org> (raw)
In-Reply-To: <20200214154854.6746-1-sashal@kernel.org>

From: Reto Schneider <reto.schneider@husqvarnagroup.com>

[ Upstream commit e8c192011c920517e5578d51c7aff0ecadd25de3 ]

The radio module asserts CTS when its RX buffer has 10 bytes left.
Putting just 8 instead of 16 bytes into the UART1 TX buffer on the Linux
side ensures to not overflow the RX buffer on the radio module side.
