/* ------ clock:
Before power on mmsys:
CLK_CFG_0_CLR (address is 0x10000048) = 0x80000000 (bit 31).
Before using DISP_PWM0 or DISP_PWM1:
CLK_CFG_1_CLR(address is 0x10000058)=0x80 (bit 7).
Before using DPI pixel clock:
CLK_CFG_6_CLR(address is 0x100000A8)=0x80 (bit 7).

Only need to enable the corresponding bits of MMSYS_CG_CON0 and MMSYS_CG_CON1 for the modules:
smi_common, larb0, mdp_crop, fake_eng, mutex_32k, pwm0, pwm1, dsi0, dsi1, dpi.
Other bits could keep 1. Suggest to keep smi_common and larb0 always clock on.

--------valid & ready
example:
ovl0 -> ovl0_mout_ready=1 means engines after ovl_mout are ready for receiving data
	ovl0_mout_ready=0 means ovl0_mout can not receive data, maybe ovl0_mout or after engines config error
ovl0 -> ovl0_mout_valid=1 means engines before ovl0_mout is OK,
	ovl0_mout_valid=0 means ovl can not transfer data to ovl0_mout, means ovl0 or before engines are not ready.
