Subject: [PATCH 1/3] ARM: imx7d: add enet2 clk sel
Date: Thu, 28 May 2020 11:31:13 +0200 [thread overview]
Message-ID: <20200528093115.28268-1-s.trumtrar@pengutronix.de> (raw)
Add clock source init for the second ethernet port.
This changes the clock direction and clock selection in a way that the
ethernet phy reference clock is routed as an output.
Signed-off-by: Steffen Trumtrar <s.trumtrar@pengutronix.de>

I know, that this is not a "good solution", but I don't know how we can
handle this in a better way. Open for suggestions.
