Subject: [PATCH 2/3] arm64: dts: imx8qxp-mek: Remove unnecessary PCIe EP vpcie-supply
Date: Sat, 9 May 2026 09:54:10 +0800 [thread overview]
Message-ID: <20260509015411.3218700-3-sherry.sun@nxp.com> (raw)
In-Reply-To: <20260509015411.3218700-1-sherry.sun@nxp.com>
For PCIe endpoint mode, only M.2 power supply needs to be ensured.
On imx8qxp-mek, the M.2 power is always on and cannot be controlled,
while reg_pcieb only controls the M.2 W_DISABLE1# signal. Remove the
unnecessary vpcie-supply property from pcie0_ep node.
Fixes: 1c9b0c6044c2 ("arm64: dts: imx8: use common imx-pcie0-ep.dtso to enable PCI ep function")
