First of all using the same node name prefix resulted in trying to
|
|
register 2 clocks under the same "clock-controller" name:
|
|
|
|
[ 0.000000] __clk_core_init: clk clock-controller already initialized

|
Secondly using any other names than "lcpll0" and "genpll" breaks output
|
|
clocks:
|
|
|
|
$ cat /sys/kernel/debug/clk/usbclk/clk_rate
|
|
0
|
|
|
|
For some reason iproc_clk_recalc_rate() gets called with "parent_rate"
|
|
argument 0 whenever clocks aren't named "lcpll0" and "genpll".
