From 0f02269b76bc25a7c9332ae8630ba407cb62f9ec Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Sat, 6 Jul 2024 18:13:02 +0200 Subject: timer: mtk: skip setting parent with dummy fixed-clock Skip setting parent with dummy fixed-clock. Upstream linux might declare an additional clock for the mtk timer and that additional clock might also be a fixed-clock defined in DT. Setting parent of a dummy fixed-clock resulta in error hence mtk timer fails to probe. Skip setting parent to permit correct probe of the mtk timer.
