Perhaps there is a bug in fdt_stringlist_search()? Can you try to debug it?

Also I see that test/dm/clk.c does not have a test for
clk_get_by_name(). If you have time, please add a test for that since
it is an important function.

[U-Boot] [bug report] Incorrect result from clk_get_by_name

[Ziyuan]

hi all,

I hit an issue about clk_get_by_name w/ fdt.
I wanna get a specified clock cell from dts via clk_get_by_name. eg:
clk_get_by_name(, "ciu-sample",..) from 'emmc: dwmmc@ff0f' on rk3288 
platform which it has four clock cell: "biu", "ciu", "ciu_drv", 
"ciu_sample".
I found that the clock list has only one element, it's "biu". I expected 
that there are four elements.


Actually, I can use clk_get_by_index instead, but I prefer clock name, 
it's more readable.
