From 04ab229fdcdd675c23e21ab2dbada8d221c7dcde Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Fri, 28 Jun 2024 19:40:53 +0200 Subject: [PATCH] clk: mediatek: provide common clk init function for infrasys Provide common clk init function for infrasys that defaults to topckgen driver if clock-parent is not defined. This is the case for upstream DTSI that doesn't provide this entry. This is needed for infracfg driver that will make use of the unified gates + muxes implementation.
