From 6905ab83b7b429bfe856536982ae00c1f594ba1f Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Thu, 28 Sep 2023 11:58:42 -0300 Subject: [PATCH] serial: amba-pl011: Do not complain when DMA is absent Many SoCs do not integrate DMA for the amba pl011 UART, causing the following message on boot: uart-pl011 80074000.serial: no DMA platform data The UART still works in PIO, so better not to print such message that may confuse people by causing them to think that there is something wrong with the UART. Change the message to debug level.
