Subject: [PATCH v3 0/4] add support for impedance control for TI dp83867 phy and fix 2nd ethernet on dra72 rev C evm
Date: Thu, 6 Oct 2016 10:43:51 +0530 [thread overview]
Message-ID: <20161006051355.15947-1-mugunthanvnm@ti.com> (raw)
Add support for configurable impedance control for TI dp83867
phy via devicetree. More documentation in [1].
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 [2]. Also pushed
a branch [3] for others to test.
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.
