Subject: [PATCH 2/2] arm64: dts: imx8mp: Drop i.MX8MP DHCOM rev.100 PHY address workaround from PDK3 DT
Date: Thu, 21 Sep 2023 21:29:33 +0200	[thread overview]
Message-ID: <20230921192933.71639-2-marex@denx.de> (raw)
In-Reply-To: <20230921192933.71639-1-marex@denx.de>

In case the i.MX8MP DHCOM rev.100 has been populated on the PDK3
carrier board, the on-SoM PHY PHYAD1 signal has been pulled high
by the carrier board and changed the PHY MDIO address from 5 to 7.
This has been fixed on production rev.200 SoM by additional buffer
on the SoM PHYAD/LED signals, remove the workaround.
