Date: Sun, 29 Jun 2014 20:35:21 -0500 From: Vince Bridgers <vbridgers2013@...il.com> To: f.fainelli@...il.com, rdunlap@...radead.org, davem@...emloft.net, netdev@...r.kernel.org Cc: vbridgers2013@...il.com, vbridger@...era.com Subject: [PATCH net v4 0/3] net: libphy: Add phy specific functions to access This set of patches addresses a problem found with the Micrel ksz9021 phy and libphy, where the ksz9021 phy does not support mmd extended register access per the IEEE specification as assumed by libphy. The first patch adds a framework for phy specific support to specify their own function to access extended phy registers, return a failure code if not supported, or to default to libphy's IEEE defined method for accessing the mmd extended phy registers. This issue was found by using the Synopsys EMAC and a Micrel ksz9021 phy on the Altera Cyclone 5 SOC development kit. This patch was tested on the same system in both positive and negative test cases. --- V4: Correct error when formatting V3 patch - erroneous text cut from code V3: Correct formatting of function arguments, remove return statement from NULL functions, and add patch for PHY driver documentation per review comments. V2: Split the original patch submission into seperate patches for the libphy framework required for the modification and for the Micrel Phy.
