From 1b91d97c66ef32a80dc3098df2f5fe3392342625 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 5 Mar 2020 15:08:22 +0200 Subject: [PATCH] serial: 8250_lpss: Add ->setup() for Elkhart Lake ports The ->setup() callback is mandatory for the devices. Provide it for Elkhart Lake UART ports. Note, for time being it's empty, but in the future it might require an additional configuration such as DMA.
