Hello,

I don't know if it is related or not, I noticed that Adam Ford's patches
commit 6d33ca36e3b ("clk: imx8mm: register UART clocks") and
commit 8999b76f238 ("clk: imx8mn: register UART clocks")
use the former name "clock-osc-24m". But Marek's patch
commit b4734c9c333 ("clk: imx: Convert clock-osc-* back to osc_*")
converted clock-osc-* to osc_*. So I think the UART clocks should also
use the current name osc_*.

Regards
Christoph
