From: Josua Mayer <jo...@solid-run.com> With a modular kernel as configured by Debian a hang was observed with the Armada 8040 SoC in the Clearfog GT and Macchiatobin boards.
The 8040 SoC actually requires four clocks to be enabled for the mdio interface to function. All 4 clocks are already specified in armada-cp110.dtsi. It has however been missed that the orion-mdio driver only supports enabling up to three clocks. This patch-set allows the orion-mdio driver to handle four clocks and adds a warning when more clocks are specified to prevent this particular oversight in the future. Josua Mayer (4): dt-bindings: allow up to four clocks for orion-mdio net: mvmdio: allow up to four clocks to be specified for orion-mdio net: mvmdio: print warning when orion-mdio has too many clocks net: mvmdio: defer probe of orion-mdio if a clock is not ready Documentation/devicetree/bindings/net/marvell-orion-mdio.txt | 2 +- drivers/net/ethernet/marvell/mvmdio.c | 11 ++++++++++- 2 files changed, 11 insertions(+), 2 deletions(-) -- 2.16.4
