Greetings,
I have developed an AM3354 based SoM and it uses an external SI5351 clock
generator to drive the clock inputs for an external duart and I2S audio
master clock. With the registration according to the documentation the
reference clock is not being detected and hence the clock generator is
not working as expect.
After trying many different things, I started to look around the mailing
lists to find information related to this issue.
I came acrossed post that has the exact same issue:
https://lkml.org/lkml/2013/2/18/468
Seeing as the patch did not land upstream, I am wondering if there is
a solution that I am not seeing.
I am willing to provide a patch given appropriate guidance.
Hi Michael,
The info on the email you referenced is kind of obsolete, TI SoCs are
calling of_clk_init() during boot now, and thus external clock nodes
should be registered fine also. Maybe you can provide the actual DTS
patch you are trying out so we can help better...? Are you seeing any
boot time error / warning prints for your new clock?
