From 4983a1517e7ddbc6f53fc07607e4ebeb51412843 Mon Sep 17 00:00:00 2001 From: Sam Shih Date: Tue, 28 Feb 2023 19:59:22 +0800 Subject: [PATCH 21/21] cpufreq: mediatek: Add support for MT7988 This add cpufreq support for mediatek MT7988 SoC. The platform data of MT7988 is different from previous MediaTek SoCs, so we add a new compatible and platform data for it.
