+Subject: [PATCH] mdio_bus: Issue GPIO RESET to PHYs.
+
+Some boards [1] leave the PHYs at an invalid state
+during system power-up or reset thus causing unreliability
+issues with the PHY which manifests as PHY not being detected
+or link not functional. To fix this, these PHYs need to be RESET
+via a GPIO connected to the PHY's RESET pin.
+
+Some boards have a single GPIO controlling the PHY RESET pin of all
+PHYs on the bus whereas some others have separate GPIOs controlling
+individual PHY RESETs.
+
+In both cases, the RESET de-assertion cannot be done in the PHY driver
+as the PHY will not probe till its reset is de-asserted.
+So do the RESET de-assertion in the MDIO bus driver.

++Common MDIO bus properties.
++
++These are generic properties that can apply to any MDIO bus.
++
++Optional properties:
++- reset-gpios: List of one or more GPIOs that control the RESET lines
++ of the PHYs on that MDIO bus.
++- reset-delay-us: RESET pulse width in microseconds as per PHY datasheet.
++
++A list of child nodes, one per device on the bus is expected. These
++should follow the generic phy.txt, or a device specific binding document.

++Example :
++This example shows these optional properties, plus other properties

+Subject: [PATCH] net: phy: Call bus->reset() after releasing PHYs from reset
+
+The API convention makes it that a given MDIO bus reset should be able
+to access PHY devices in its reset() callback and perform additional
+MDIO accesses in order to bring the bus and PHYs in a working state.
+
+Commit 69226896ad63 ("mdio_bus: Issue GPIO RESET to PHYs.") broke that
+contract by first calling bus->reset() and then release all PHYs from
+reset using their shared GPIO line, so restore the expected
+functionality here.
