[PATCH 02/12] ARM: dts: imx7d: cl-som-imx7: add phy-reset-gpios

From: Andrà Draszik
Date: Mon Aug 26 2019 - 11:38:52 EST


According to the design team:
* reset input PHY0 is directly connected to the
corresponding pin GPIO1_4 in the i.MX7
* reset for PHY1 is done using the gpio expander bit 4

While touching this area, also add a 'compatible'
to the phy to make it more clear what this is and
which driver handles this - an Ethernet phy attached
to mdio, handled by of_mdio.c
