Re: [PATCH v2 0/2] clk: ti: mux: resolve parent clocks by DT index, not by name

[Andreas Kemnade]

Hi,

this seems to produce on OMAP3 (DM3730), even with the init fix.

[    0.000000] clocksource: 32k_counter: mask: 0xffffffff max_cycles: 0xffffffff
, max_idle_ns: 58327039986419 ns                                                
[    0.000030] sched_clock: 32 bits at 33kHz, resolution 30517ns, wraps every 65
535999984741ns                                                                  
[    0.013488] clk: failed to reparent gpt1_fck to omap_32k_fck: -22            
[    0.019805] Failed to initialize '/ocp@68000000/target-module@48318000/timer@
0': -19                                                                         

Regards,
Andreas
