Yes, I sent a patch. Then he sent another patch which breaks things differe= ntly. I have not yet submitted my fix. My fix is to revert his patch, and t= hen modify your updated device trees to automatically set the tbi to someth= ing. On Nov 24, 2011, at 1:51, "Kumar Gala" [off-list ref] wrote:

Fix this by moving the of_mdiobus_register() call earlier. =20 Cc: Andy Fleming <redacted> Signed-off-by: Baruch Siach <baruch@tkos.co.il> --- drivers/net/ethernet/freescale/fsl_pq_mdio.c | 14 +++++++------- 1 files changed, 7 insertions(+), 7 deletions(-) =20diff --git a/drivers/net/ethernet/freescale/fsl_pq_mdio.c b/drivers/net=
