From f596b01b9a69a8fd486468a11f6b2dbf07984c5f Mon Sep 17 00:00:00 2001 From: Christine Gharzuzi Date: Wed, 23 May 2018 12:10:36 +0300 Subject: [PATCH] phy: marvell: fix handling of unconnected comphy - the default value of comphy pipe selector is set to PCIe (x4) in case of unconnected comphy the default value remains 0x4 which may lead to several issues with comphy initialization. - this patch adds SMC call that powers off the comphy lane in case of unconnected comphy.
