From 7db3cde5123e2acdd65ff7458628a9835c804b27 Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Fri, 4 Jun 2021 19:08:44 +0200 Subject: [PATCH] ARM: dts: meson: Set the fifo-size of uart_A to 128 bytes The first UART controller in the "Everything-Else" power domain is called uart_A. Unlike all other UARTs (which use a 64 byte fifo-size in hardware) uart_A has a fifo-size of 128 bytes. This UART controller is typically used for Bluetooth HCI. The fifo-size of 128 bytes is valid from all SoCs from Meson6 (or possibly even earlier) all the way up to the latest 64-bit ones.
