Hi, John
Are you using i.MX6 series SOC? If yes, then I think you can just set the CCM_CLKO1 to output a clock source which listed in the CCM_CCOSR, both clko1_sel and clko2_sel can be set to output to CCM_CLKO1. But I am not sure whether there is a clock source in the list having its freq=24.576MHz. if yes, then you can get it, just need to set the IOMUX to CCM_CLKO, then set the CCM_CCOSR register to select the clock source you wanted.
Hello all
I use imx6 Solo
with 24M crystal as source .
I tried from osc_clock and pll4 clock
In my test , CCM_CLKO1 just output 24M not 24.576M,even from pll4 , I set pll4 with (24*(12+288/1000))/4
And , with CLKO2_EN , CLK02_DIV = 7 ,CLKO2_SEL = 2 CLK_OUT_SET = 1 from usdhc4 usdhc4 use 198M clock ,I just get 49.5M not 24.75M
Do you have any errta about this ?

Dear Yongcai,
When cpu imx6 is in sleep status, CCM_CLKO1 still can provide clock?

Thanks your response!
select CCM_CLKO1 to 32.768Hhz by setting CLKO1_SEL 1110 ckil_sync_clk_root. then soc enter wait or standby mode.
I can't find whether ckil_sync_clk_root is available on wait or standby mode on <IMX6DQRM.pdf>
