Subject: [PATCH] tty: serial: fsl_lpuart: increase maximum uart_nr to 12
Date: Fri, 3 Jan 2025 15:11:54 +0800 [thread overview]
Message-ID: <20250103071154.3070924-1-sherry.sun@nxp.com> (raw)
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.
