Subject: [PATCH 1/2] ARM: dts: meson: Add the Ethernet "timing-adjustment" clock
Date: Tue, 12 May 2020 23:51:47 +0200 [thread overview]
Message-ID: <20200512215148.540322-2-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20200512215148.540322-1-martin.blumenstingl@googlemail.com>
Add the "timing-adjusment" clock now that we now that this is connected
to the PRG_ETHERNET registers. It is used internally to generate the
RGMII RX delay no the MAC side (if needed).
