Can I please check there is no mistake in your description. I have been repeatedly
told by the hardware engineers here, (for the past 6 years) it is not possible.
But, you seem to have an R-Car H2 with the AD silicon version of DA9063?
Regards,
Steve

I am confused, what is not possible? That I have an AD version? Yes, we
found that out when we worked on the RTC recently. It is an early
version of the Lager development board. I have no numbers but my
assumption is there are not too many out there.
Hi Wolfram,
No problem.

Sure, I know, people have been requesting continued support for DA9063 AD silicon
for years. The original DA9063 Linux driver was sent to LKML with AD support.

Thanks, yes, there is interest from the hardware engineers here. Thanks for the
confirmation about your board. I will inform them about the DA9063 AD silicon on
the Renesas Lager board -- and I will let you know their response.

Steve

I see. Well, unlike the RTC patches recently, this watchdog patch is
independent of the variant AFAICS, or?

Agreed!
I am going to test your watchdog changes with a later silicon version later today
and I expect no problems.

Hi Geert,
Thanks.

Thanks for the hardware details. I re-iterated the info from Wolfram's last e-mail to the
hardware engineers during this morning's meeting. It can also be looked up on LKML if
needed. I will pass on the details you have sent, next.
To be clear -- I am treating these informal conversations on LKML as a data collection
exercise and for them to be used as information-only. But, I pushed-back again and asked for
any discussions to go through more formal channels and not to require me as a go-between,
or to include the involvement of individuals like yourselves, or to use the LKML channel.
This is not patch related and I don't want to request any more of anybody's time.
Regards,
Steve

For the record, I see the following DA9063 variants on the Renesas boards I have
access to:
- DA9063 AD: Lager (R-Car H2), Koelsch (R-Car M2-W),
- DA9063 BB: Gose (R-Car M2-N), Blanche (R-Car V2H), Alt (R-Car E2).
I cannot check Porter (R-Car M2-W) and Silk (R-Car E2) right now, but
from Marek's report, Porter has DA9063L CA.
Marek: which variant does your Stout (R-Car H2) have?
Thanks!
