Subject: [PATCH v3 3/3] clk: nuvoton: Use clk_parent_data instead of string for parent clock
Date:   Thu, 22 Jun 2023 14:13:43 +0000

From: Jacky Huang <ychuang3@nuvoton.com>

For the declaration of parent clocks, use struct clk_parent_data instead
of a string. Due to the change in the passed arguments, replace the usage
of devm_clk_hw_register_mux() with clk_hw_register_mux_parent_data() for
all cases.
