Hm, that doesn't sound right. Don't we currently have Gate+Divider combo in
the l3_mp_clk? If you turn off the clock gate from the l3_mp_clk, then l3_sp_clk
would also be turned off.
But according to Figure 2-3 in cv_5v4.pdf

	DIV1 --------> GATE -----> L3_MP_CLK
                 |
		 |---- DIV2 -----> L3_SP_CLK

So, l3_sp_clk's parent is the divider of l3_mp_clk but NOT the gate.

Regards,
Steffen
