From ff578db7b69374fb632ed76e8fd5406f9466c5bd Mon Sep 17 00:00:00 2001 From: kartik Date: Thu, 20 Jan 2022 15:41:51 +0530 Subject: [PATCH] arm64: tegra: Enable UART instance on 40-pin header On P3737 board, UART-A is available on 40-pin header. Enable UART-A for P3737 and change the compatible string to "nvidia,tegra194-hsuart". This allows supporting HW flow control and is the preferred choice for higher baud rates.
