Subject: [PATCH netdev] net: stmmac: dwmac-sun8i: Allow all RGMII modes
Date: Mon, 6 Jan 2020 11:09:45 +0800 [thread overview]
Message-ID: <20200106030945.19774-1-wens@kernel.org> (raw)
From: Chen-Yu Tsai <wens@csie.org>
Allow all the RGMII modes to be used. This would allow us to represent
the hardware better in the device tree with RGMII_ID where in most
cases the PHY's internal delay for both RX and TX are used.
Fixes: 9f93ac8d4085 ("net-next: stmmac: Add dwmac-sun8i")
Signed-off-by: Chen-Yu Tsai <wens@csie.org>

Maybe CC stable so future device trees can be used with stable kernels?
