From a94737a6652bd9fe2db4161e2b81dce58505b4cc Mon Sep 17 00:00:00 2001 From: Laura Nao Date: Mon, 15 Sep 2025 17:19:28 +0200 Subject: [PATCH] clk: mediatek: clk-mtk: Add MUX_DIV_GATE macro MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit On MT8196, some clocks use one register for parent selection and gating, and a separate register for frequency division. Since composite clocks can combine a mux, divider, and gate in a single entity, add a macro to simplify registration of such clocks by combining parent selection, frequency scaling, and enable control into one definition.
