From 149468699e8f631f69d55b5c86b430824fc32d69 Mon Sep 17 00:00:00 2001 From: Horatiu Vultur Date: Thu, 23 May 2019 21:45:33 +0200 Subject: [PATCH] net: mscc: serval: Remove delay when serdes is configured When serdes configuration was written in hardware there was a delay of 100ms to be sure that configuration was written. But the delay is not needed because already the function serdes_write it is checking that the operation finished. Therefore remove the mdelay. This improves the speed of configuring the network driver.
