| 2012-04-27 | davinci_mdio: Fix MDIO timeout check | Christian Riesch | |
| commit 5b76d0600b2b08eef77f8e9226938b7b6bde3099 upstream. Under heavy load (flood ping) it is possible for the MDIO timeout to expire before the loop checks the GO bit again. This patch adds an additional check whether the operation was done before actually returning -ETIMEDOUT. To reproduce this bug, flood ping the device, e.g., ping -f -l 1000 After some time, a "timed out waiting for user access" warning may appear. And even worse, link may go down since the PHY reported a timeout. Signed-off-by: Christian Riesch <christian.riesch@omicron.at> Cc: Cyril Chemparathy <cyril@ti.com> Signed-off-by: David S.

| 2010-09-24 | net: davinci_emac: separate out davinci mdio | Cyril Chemparathy | |
| Davinci's MDIO controller is present on other TI devices, without an accompanying EMAC. For example, on tnetv107x, the same MDIO module is used in conjunction with a 3-port switch hardware. By separating the MDIO controller code into its own platform driver, this patch allows common logic to be reused on such platforms.
