Subject: [PATCH 07/16] ARM: dts: at91: sama5d2: Specify the FIFO size for the Flexcom UART
Date: Thu, 14 May 2020 05:03:11 +0000	[thread overview]
Message-ID: <20200514050301.147442-8-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20200514050301.147442-1-tudor.ambarus@microchip.com>

From: Tudor Ambarus <tudor.ambarus@microchip.com>

The UART submodule in Flexcom has 32-byte Transmit and Receive FIFOs.
Tested uart7 on sama5d2-icp, which has both DMA and FIFO enabled.

Signed-off-by: Tudor Ambarus <tudor.ambarus@microchip.com>
