Subject: [PATCH v1] arm64: dts: verdin-imx8mp: add pcie support
Date: Wed, 14 Dec 2022 07:13:54 +0100 [thread overview]
Message-ID: <20221214061354.174072-1-marcel@ziswiler.com> (raw)
From: Marcel Ziswiler <marcel.ziswiler@toradex.com>
Add PCIe support on the Verdin iMX8M Plus.
Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>

This has successfully been tested with Lucas' imx8mp-hsio-blk-ctrl high
performance PLL clock exposure patch set [1] a later version thereof
hopefully may land together with my humble patch. Thanks!
