Subject: ramips: fix up switch settings for Sitecom WL-351 v1 002
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d09f0045ea2f7fb142e23d8f5cdd45e48a3dcc26;p=openwrt%2Fstaging%2Fynezz.git

ramips: fix up switch settings for Sitecom WL-351 v1 002

Pinmux for rgmii needs to be set to rgmii, not gpio.
Hide the ESW switch on boot (using new rgmii esw devicetree attribute).
Also add a Sitecom-specific profile, since the image needs to include
the rtl8366 kernel driver.
