Subject: [PATCH] cpufreq: mediatek: Add support for MT7988A
Message-ID:
<acf4fb446aacfbf6ce7b6e94bf3aad303e0ad4d1.1713545923.git.daniel@makrotopia.org>
Content-Disposition: inline
List-Id: <linux-mediatek.lists.infradead.org>
From: Sam Shih <sam.shih@mediatek.com>
This add cpufreq support for mediatek MT7988A SoC.
The platform data of MT7988A is different from previous MediaTek SoCs,
so we add a new compatible and platform data for it.
