Add support for configurable impedance control for TI dp83867 phy via devicetree. More documentation in . CPSW second ethernet is not working, fix it by enabling impedance configuration on the phy.
Verified the patch on DRA72 Rev C evm, logs at . Also pushed a branch  for others to test. Changes from v3: * Fixup change log text and no code changes. Changes from v2: * Fixed a typo in dts and driver. Changes from initial version: * As per Sekhar's comment, instead of passing impedance values, change to max and min impedance from DT * Adopted phy_read_mmd_indirect() to cunnrent implementation. * Corrected the phy delay timings to the optimal value.  - http://www.ti.com/lit/ds/symlink/dp83867ir.pdf  - http://pastebin.ubuntu.com/23343139/  - git://git.ti.com/~mugunthanvnm/ti-linux-kernel/linux.git dp83867-v4 Mugunthan V N (4): net: phy: dp83867: Add documentation for optional impedance control net: phy: dp83867: add support for MAC impedance configuration ARM: dts: dra72-evm-revc: add phy impedance settings ARM: dts: dra72-evm-revc: fix correct phy delay .../devicetree/bindings/net/ti,dp83867.txt | 12 ++++++++++ arch/arm/boot/dts/dra72-evm-revc.dts | 10 ++++---- drivers/net/phy/dp83867.c | 28 ++++++++++++++++++++++ 3 files changed, 46 insertions(+), 4 deletions(-) -- 184.108.40.2065.g3cdd5d1
