From: Sergei Shtylyov <redacted> With the phylib now being aware of the "reset-gpios" PHY node property, there should be no need to frob the PHY reset in this driver anymore... Signed-off-by: Sergei Shtylyov <redacted> Acked-by: Nicolas Ferre <redacted> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- v4: - Add Reviewed-by, v3: - Resolve rejects due to the file being renamed, refresh the patch, - Add code to reset PHY on probe error, - Edit patch description, - Take over from Sergei, - Add Acked-by, v2: - No changes. --- drivers/net/ethernet/cadence/macb.h | 1 - drivers/net/ethernet/cadence/macb_main.c | 21 --------------------- 2 files changed, 22 deletions(-)
