This is w.r.t J6/J6eco: 32clk is pseudo (erratum i856) - clock source.
Errata i856 for the AM572x (DRA7xx) points out that the 32.768KHz
external
crystal is not enabled at power up. Instead the CPU falls back to using
an emulation for the 32KHz clock which is SYSCLK1/610.  SYSCLK1 is
usually
20MHz on boards so far (which gives an emulated frequency of 32.786KHz)

Thanks applying into omap-for-v4.6/fixes.

Actually let's wait a review from Tero on this one, not sure
about the pseudo clock naming here. So dropping for now.

The patch is fine for me, I didn't comment anything before as I thought
you already applied it.

Acked-by: Tero Kristo <t-kristo@xxxxxx>

Thanks Tero.

OK applying with Tero's ack.

I'm dropping this again as it introduces new warnings with make dtbs:

Looks like a merge conflict to me, sys_32k_ck has gone under clockdomains for some reason. It should be under clocks.
