drivers: net: xgene: Remove return statement from void function

2017-09-05T21:58:25Z

commit 183db4 ("drivers: net: xgene: Correct probe sequence handling") changed the return type of xgene_enet_check_phy_handle() to void. This patch, removes the return statement from the last line. Signed-off-by: Iyappan Subramanian Signed-off-by: David S. Miller

drivers: net: xgene: Correct probe sequence handling

2017-08-29T23:13:08Z

The phy is connected at early stage of probe but not properly disconnected if error occurs. This patch fixes the issue. Also changing the return type of xgene_enet_check_phy_handle(), since this function always returns success. Signed-off-by: Quan Nguyen Signed-off-by: Iyappan Subramanian Signed-off-by: David S.

xgene: Always get clk source, but ignore if it's missing for SGMII ports

2017-08-04T18:30:37Z

Even the driver doesn't do anything with the clk source for SGMII ports it needs to be enabled by doing a devm_clk_get(), if there is a clk source in DT.

xgene: Don't fail probe, if there is no clk resource for SGMII interfaces

2017-07-13T16:21:15Z

This change fixes following problem [ 1.827940] xgene-enet: probe of 1f210030.ethernet failed with error -2 which leads to a missing ethernet interface (reproducable at least on Gigabyte MP30-AR0 and APM Mustang systems). The check for a valid clk resource fails, because DT doesn't provide a clock for sgenet1. But the driver doesn't use this clk, if the ethernet port is connected via SGMII. Therefore this patch avoids probing for clk on SGMII interfaces. Fixes: 9aea7779b764 ("drivers: net: xgene: Fix crash on DT systems") Signed-off-by: Thomas Bogendoerfer Signed-off-by: David S.

drivers: net: xgene: Fix redundant prefetch buffer cleanup

2017-05-16T15:41:11Z

Prefetch buffer cleanup code was called twice, causing EDAC to report errors during reboot.
