From 037ee58e0ae5bc48e770c2256dc06d6a82ade428 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 25 Jun 2024 14:11:09 +0200 Subject: arm64: dts: imx8mp: Do not reconfigure Audio PLL2 on DH i.MX8M Plus DHCOM SoM The DH i.MX8M Plus DHCOM SoM uses Audio PLL2 to supply clock to CLKOUT2 output. Those clock are used to supply on-SoM TC9595 DSI-to-(e)DP bridge with RefClk and must not be reconfigured, otherwise the bridge cannot work correctly. Stop reconfiguring Audio PLL2 on this SoM.
