From 320a3ecef7e85b8d2cdf549a292045d520a2171a Mon Sep 17 00:00:00 2001 From: Caleb Connolly Date: Wed, 3 Apr 2024 14:07:44 +0200 Subject: [PATCH] serial: msm-geni: support livetree When using OF_LIVE, the debug UART driver won't be probed if it's a subnode of the geni-se-qup controller. Add a NOP driver for the controller to correctly discover its child nodes.
