From 025822884a4fd2d0af51dcf77ddc494e60c5ff63 Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Wed, 6 Jan 2021 14:42:48 +0100 Subject: [PATCH] net: stmmac: dwmac-meson8b: fix enabling the timing-adjustment clock The timing-adjustment clock only has to be enabled when a) there is a 2ns RX delay configured using device-tree and b) the phy-mode indicates that the RX delay should be enabled. Only enable the RX delay if both are true, instead of (by accident) also enabling it when there's the 2ns RX delay configured but the phy-mode incicates that the RX delay is not used.
