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

From: André Draszik <[email-masked]>
Date: Mon, 26 Aug 2019 16:37:50 +0100

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
