From: Marek Vasut Date: Thu, 25 Sep 2025 20:51:55 +0000 (+0200) Subject: arm64: dts: freescale: add initial support for i.MX 95 Verdin Evaluation Kit (EVK) X-Git-Tag: v6.19-rc1~100^2~20^2~104 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2a119550822d1c2bd14ef245a57bfeabc90eca0d;p=thirdparty%2Fkernel%2Flinux.git arm64: dts: freescale: add initial support for i.MX 95 Verdin Evaluation Kit (EVK) Add initial support for i.MX 95 Verdin Evaluation Kit (EVK), which used to be the Titan EVK. Currently supported is lpuart1 as console, SDHC1/2/3 as storage, WM8904 Audio, USB3.0 and ENETC ethernet RGMII Gigabit port. Note that the SoM used in this EVK is a derivative SoM from Verdin line of SoMs, an actual i.MX95 Verdin SoM is under development.
