Could you grab the clock tree from /sys/kernel/debug/clk/clk_summary for the clk_hdmi_cec tree?
Here it is: enable prepare protect duty hardware clock count count count rate accuracy phase cycle enable
clk_rtc32k_frac 1 1 0 32768 0 0 50000 Y clk_rtc_32k 1 1 0 32768 0 0 50000 Y clk_hdmi_cec 1 2 0 32768 0 0 50000 Y
You are on the clk_rtc32k_frac which is a fractional divider that is fed from the 24m clock. Your clock likely isn't the issue here. I'd recommend setting up the cec-gpio node to validate your hardware works.
