[U-Boot] [PATCH v2 1/3] phy: atheros: Use ar8035_config for AR8031

[U-Boot] [PATCH v2 1/3] phy: atheros: Use ar8035_config for AR8031

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@nxp.com>

Commit 08ad9b068afb88 (" ar8031: modify the config func of ar8031 to
ar8021_config") selected 'ar8021_config' as the configuration function
for AR8031.

The correct would be to use 'ar8035_config' instead as AR8031/AR8035
have the same programming model and even share the same phy driver
in the linux kernel: drivers/net/phy/at803x.c.

Tested on a mx6qsabresd and wandboard, which now can work without
any PHY setup code in the board files.

[U-Boot] [PATCH v2 2/3] mx6sabresd: Simplify the Ethernet PHY configuration

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@nxp.com>

As per the AR8031 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 also add a 100us delay after deasserting the
reset line to guarantee that the PHY ID can be read correctly and the
Atheros 8031 PHY driver can be loaded automatically.

This results in a simpler code.

[U-Boot] [PATCH v2 3/3] wandboard: Simplify the Ethernet PHY configuration

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@nxp.com>

As per the AR8031 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 also add a 100us delay after deasserting the
reset line to guarantee that the PHY ID can be read correctly and the
Atheros 8031 PHY driver can be loaded automatically.

This results in a simpler code.
