From 1dc3871ce7ec819030c22297f8960c61cc42a990 Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Wed, 30 Sep 2026 19:24:51 +0200 Subject: [PATCH] clk: nuvoton: ma35d1: Add missing WDT/WWDT parent clocks The WDT and WWDT muxes list PCLK3/4096 and PCLK4/4096 among their possible parents, but the driver never registers the corresponding clocks, so these parents could never be used. Add pclk3_div4096 and pclk4_div4096 as fixed factor children of pclk3 and pclk4 and expose them through the clock provider.
