From 257a34a028aef463357441504a882f9be7f7e0e9 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Beno=C3=AEt=20Monin?= Date: Mon, 20 Oct 2025 15:28:56 +0200 Subject: clk: fixed-factor: Export __clk_hw_register_fixed_factor() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Make the base registration function for fixed-factor clocks public and re-implement the various registration functions that are a direct call to __clk_hw_register_fixed_factor() as macros. This is similar to how the registration functions of divider, mux and other clocks are implemented. Add a new macro clk_hw_register_fixed_factor_pdata() to register a fixed-factor clock with its parent clock passed as a struct clk_parent_data.
