LCDC_EN Usage of iMX25

Hi chip experts,

 

I think there are 3 clock domains(AHB,PER&IPG) in the LCD Controller (LCDC) and all of regs are in the AHB domain.

I want to make sure the proper usage of LCDC_EN which is IPG Clock Gating[29].

 

(Q) Is it OK to leave LCDC_EN clear (=no ipg clock) when write regs?

 

Because I don't want to make any noise during startup. Can anyone help me?

Thanks.
