Original cover letter: So I managed to discovered how to fix inband AN for 2500base-x mode on 88E6393x (Amethyst) family. This series fixes application of erratum 4.8, adds fix for erratum 5.2, adds support for completely disablign SerDes receiver / transmitter, fixes inband AN for 2500base-x mode by using 1000base-x mode and simply changing frequeny to 3.125 GHz, all this for 88E6393X. The last commit fixes linking when link partner has AN disabled and the device invokes the AN bypass feature. Currently we fail to link in this case. Changes since v1: - fixed wrong operator in patch 3 (thanks Russell) - added more comments about why BMCR_ANENABLE is used in patch 6 (thanks Russell) - updated some return statements from if (something) return func(); return 0; to if (something) err = func(); return err; (err is set to 0 before the condition) Marek Marek Behún (6): net: dsa: mv88e6xxx: Fix application of erratum 4.8 for 88E6393X net: dsa: mv88e6xxx: Drop unnecessary check in mv88e6393x_serdes_erratum_4_6() net: dsa: mv88e6xxx: Save power by disabling SerDes trasmitter and receiver net: dsa: mv88e6xxx: Add fix for erratum 5.2 of 88E6393X family net: dsa: mv88e6xxx: Fix inband AN for 2500base-x on 88E6393X family net: dsa: mv88e6xxx: Link in pcs_get_state() if AN is bypassed drivers/net/dsa/mv88e6xxx/serdes.c | 252 +++++++++++++++++++++++++---- drivers/net/dsa/mv88e6xxx/serdes.h | 4 + 2 files changed, 224 insertions(+), 32 deletions(-)
