If anyone has any objections, please let me know. ------------------ From: Siddharth Vadapalli commit 320d8a84f6f045dc876d4c2983f9024c7ac9d6df upstream. Since "serdes0" and "serdes1" which are the sub-nodes of "serdes_wiz0" and "serdes_wiz1" respectively, have been disabled in the SoC file already, and, given that these sub-nodes will only be enabled in a board file if the board utilizes any of the SERDES instances and the peripherals bound to them, we end up in a situation where the board file doesn't explicitly disable "serdes_wiz0" and "serdes_wiz1". As a consequence of this, the following errors show up when booting Linux: wiz bus@f0000:phy@f000000: probe with driver wiz failed with error -12 ... wiz bus@f0000:phy@f010000: probe with driver wiz failed with error -12 To not only fix the above, but also, in order to follow the convention of disabling device-tree nodes in the SoC file and enabling them in the board files for those boards which require them, disable "serdes_wiz0" and "serdes_wiz1" device-tree nodes.
