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.
|
|
|
|
Fixes: 69226896ad63 ("mdio_bus: Issue GPIO RESET to PHYs.")
