Subject: [PATCH AUTOSEL 5.1 28/70] net: stmmac: dwmac-mediatek: modify csr_clk value to fix mdio read/write fail
Date: Sat,  8 Jun 2019 07:39:07 -0400	[thread overview]
Message-ID: <20190608113950.8033-28-sashal@kernel.org> (raw)
In-Reply-To: <20190608113950.8033-1-sashal@kernel.org>

From: Biao Huang <biao.huang@mediatek.com>

[ Upstream commit f4ca7a9260dfe700f2a16f0881825de625067515 ]

1. the frequency of csr clock is 66.5MHz, so the csr_clk value should
be 0 other than 5.
2. the csr_clk can be got from device tree, so remove initialization here.

Fixes: 9992f37e346b ("stmmac: dwmac-mediatek: add support for mt2712")
