| |
Hi,
This might be a stupid question, but I'm somehow stuck here. I'm using a driver with the following DTS sub-node:
ref25: ref25M { compatible = "fixed-clock"; #clock-cells = <0>; clock-frequency = <25000000>; };
clock-generator@0 { /* ... */ #clock-cells = <1>; clocks = <&ref25>; }
The device driver for clock-generator uses something like the following call to get its clock:
clk = of_clk_get(np, 0);
but the return value is ERR_PTR(-ENOENT) and I also can't find this clock in the clk debugfs tree.
This is on a OMAP/AM33xx device with kernel 3.8-rc7 plus the -next tips of arm-soc and omap, but with no other special clock options selected in the config. Is there anything I'm missing to correctly instantiate the dummy clock?
Thanks for a pointer, Daniel
