From 4835efca7a004fab62853f3e6bbd2854d1df503b Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 29 Nov 2024 01:35:43 +0100 Subject: [PATCH] ARM: dts: imx: Enable PCIe and NVMe on Data Modul i.MX8M Mini eDM SBC Enable PCIe/NVMe support on Data Modul i.MX8M Mini eDM SBC. Except for the configuration options which are enabled, add slight adjustment to board u-boot.dtsi, which is necessary as there is currently no driver for the I2C PCIe clock generator. Since the generator is strapped to be always on, it is possible to supplant the generator functionality by fixed-clock.
