Subject: [PATCH 1/2] arm64: dts: imx8mp: Initialize audio PLLs from audiomix subsystem
Date: Thu, 9 May 2024 13:14:57 +0800 [thread overview]
Message-ID: <1715231698-451-2-git-send-email-shengjiu.wang@nxp.com> (raw)
In-Reply-To: <1715231698-451-1-git-send-email-shengjiu.wang@nxp.com>
Initialize audio PLL1 as the parent clock for 8kHz series rates,
audio PLL2 as the parent clock for 11kHz series rates. that PLL1
and PLL2 can together support full range of audio sample rates.
