From aa0a79f3373cccee70923f252111b404d66dfa1a Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 24 Apr 2024 01:15:18 +0200 Subject: [PATCH] ARM: dts: imx: Enable PCIe and NVMe on DH i.MX8M Plus DHCOM PDK3 Enable PCIe/NVMe support on DH i.MX8M Plus DHCOM PDK3. 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.
