[PATCH v1] arm64: dts: imx943-evk: Remove 'supports-clkreq' from PCIe1

From: <hidden>
Date: 2026-07-14 04:01:57
Also in: imx, linux-devicetree, lkml
Subsystem: arm/freescale imx / mxc arm architecture, the rest · Maintainers: Frank Li, Sascha Hauer, Linus Torvalds

From: Richard Zhu <hongxing.zhu@nxp.com>

Remove the 'supports-clkreq' property from PCIe1 as the standard PCIe
slot on i.MX943 EVK may not have CLKREQ# signal wired, causing
compatibility issues with some PCIe cards.

Fixes: 9a8f11f6f786 ("arm64: dts: imx943-evk: Add pcie[0,1] and pcie-ep[0,1] support")
