Subject: [PATCH] ARM: dts: Fix Ethernet support
Date: Tue, 14 Sep 2021 11:49:46 -0300	[thread overview]
Message-ID: <20210914144946.2010617-1-festevam@gmail.com> (raw)

Currently, it is no longer possible to retrieve a DHCP address
on the imx6qdl-pico board.

This issue has been exposed by commit f5d9aa79dfdf ("ARM: imx6q:
remove clk-out fixup for the Atheros AR8031 and AR8035 PHYs").

Fix it by describing the qca,clk-out-frequency property as suggested
by the commit above.

Fixes: 98670a0bb0ef14bbb3 ("ARM: dts: imx6qdl: Add imx6qdl-pico support")
