From: Prasanna Kumar <prasanna.ps at samsung.com>

Gscaler :

  1. For "aclk_300_gscl",following clocks are added
          Mux clocks
                mout_aclk_300_gscl_mid,
                mout_aclk_300_gscl_mid1,
                mout_aclk_300_gscl
          Divider clock
                div_aclk300_gscl
          Sub-Mux clock ( driven from output of divider clock)
                mout_sub_aclk300
  2. For "aclk_266_gscl",
           Sub-Mux clock "mout_sub_aclk266" added
           Divider clock has been modified to refer Sub-Mux clock

MFC :
   For "aclk_333"
        Sub-Mux clock "mout_sub_aclk333" added
           Divider clock has been modified to refer Sub-Mux clock
