So I will need to manually setup the parents to make sure CCF doesn't make a random choice. Then I'll be able to do a set_rate on vclk to setup the proper PLL rate. > >> +#define CLKID_CTS_ENCI 199 >> +#define CLKID_CTS_ENCP 200 >> +#define CLKID_CTS_VDAC 201 >> +#define CLKID_HDMI_TX 202 > is my assumption correct that you need to choose a specific input > clock (VCLK or VCLK2) for a specific use-case (ENCI, ENCP, VDAC, > HDMI_TX)? > let's say HDMI uses VLKC2 as input (I'm not sure if it really does): > could you skip the VCLK_DIV_* parents in the HDMI_TX clock definition > - or does the selection of a specific parent clock (VCLK or VCLK2) > depend on the output rate? HDMI takes vclk2 (why ? I'll keep this path since it's always used by the vendor code), and CBVS takes vclk. I suspect they tried to make is possible to have CVBS and HDMI output work at the same time using the VPP2 instance. But no idea how it works. As I sais before, you need to feed a x2 factor to hdmi and enci/encp for some modes, and I can't let CCF decide since they must take the same clock path (VCLK or VCLK2, not both). > > > Regards > Martin > Neil
