Fabio Estevam 4b421d4ea1 mx6cuboxi: Fix the reset delay for the AR8035 PHY ... Since commit 59370f3fcd ("net: phy: delay only if reset handler is registered") Ethernet is no longer functional: Booting from net ... FEC Waiting for PHY auto negotiation to complete......... TIMEOUT ! BOOTP broadcast 1 BOOTP broadcast 2 BOOTP broadcast 3 BOOTP broadcast 4 This commit does not have an issue in itself, but it revelead a problem with the Ethernet initialization. As per the AR8035 datasheet: "For a reliable power on reset, suggest to keep asserting the reset low long enough (10ms) to ensure the clock is stable and clock-to-reset 1ms requirement is satisfied." So do as suggested and keep the reset low for 10ms. Also add a 100us delay after deasserting the reset line to guarantee that the PHY ID can be read correctly and the Atheros PHY can be loaded as per Troy Kisky's suggestion.
