From 3e4f74e0ea5a6a6d6d825fd7afd8a10afbd1152c Mon Sep 17 00:00:00 2001 From: Yong Wu Date: Tue, 14 Sep 2021 19:36:58 +0800 Subject: memory: mtk-smi: Add clocks for smi-sub-common SMI sub common only have one output port. thus it has only one gals clocks(gals0). then, smi-sub-common require the three clocks(apb/smi/gals0) in has_gals case.
