K 10 svn:author V 6 adrian K 8 svn:date V 27 2013-10-15T03:28:32.366151Z K 7 svn:log V 517 Update the AR934x SoC support. * Add the MDIO clock probe during clock initialisation; * Update the ethernet PLL configuration function to use the correct values; * Add a GMAC block configuration to pull the configuration out of hints; * Add an ethernet switch reconfiguration method. Tested: * AR9344 SoC (DB120) .. however, this has been tested with extra patches in my tree (to fix the ethernet/MDIO support, SPI support, ethernet switch support) and thus it isn't enough to bring the full board support up.
