From fba725f41002e5035e601a7cfa9429b0c8184211 Mon Sep 17 00:00:00 2001 From: Janine Hagemann Date: Tue, 28 Aug 2018 08:25:37 +0200 Subject: net: phy: ti: Add lane swapping support in the DP83867 TI's PHY driver This patch adds support for enabling or disabling the lane swapping (called "port mirroring" in PHY's CFG4 register) feature of the DP83867 TI's PHY device. One use case is when bootstrap configuration enables this feature (because of e.g. LED_0 wrong wiring) so then one needs to disable it in software (at u-boot/Linux). Based on commit fc6d39c39581 ("net: phy: dp83867: Add lane swapping support in the DP83867 TI's PHY driver") of mainline linux kernel.
