From 79d65fda55cf1a6dac96a69913cd2294a3d8948a Mon Sep 17 00:00:00 2001 From: Sherry Sun Date: Fri, 3 Jan 2025 15:11:54 +0800 Subject: [PATCH] tty: serial: fsl_lpuart: increase maximum uart_nr to 12 Some SoCs like the i.MX943 have aliases for up to 12 UARTs, need to increase UART_NR from 8 to 12 to support lpuart9-12 to avoid initialization failures.
