From 32c055ef563c3a4a73a477839f591b1b170bde8e Mon Sep 17 00:00:00 2001 From: Michel Alex Alex.Michel@wiedemann-group.com Date: Mon, 2 Sep 2024 09:05:53 +0000 Subject: [PATCH] clk: imx6ul: fix clock parent for IMX6UL_CLK_ENETx_REF_SEL
Commit 4e197ee880c24ecb63f7fe17449b3653bc64b03c ("clk: imx6ul: add ethernet refclock mux support") sets the internal clock as default ethernet clock.
Since IMX6UL_CLK_ENET_REF cannot be parent for IMX6UL_CLK_ENET1_REF_SEL, the call to clk_set_parent() fails. IMX6UL_CLK_ENET1_REF_125M is the correct parent and shall be used instead. Same applies for IMX6UL_CLK_ENET2_REF_SEL, for which IMX6UL_CLK_ENET2_REF_125M is the correct parent.
