From e8c192011c920517e5578d51c7aff0ecadd25de3 Mon Sep 17 00:00:00 2001 From: Reto Schneider Date: Tue, 14 Jan 2020 09:48:06 +0100 Subject: [PATCH] MIPS: ralink: dts: gardena_smart_gateway_mt7688: Limit UART1 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.
