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?

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.

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. Regards, Steve ^ permalink raw reply [flat|nested] 8+ messages in thread

The original DA9063 Linux driver was sent to LKML with AD support. I see. Well, unlike the RTC patches recently, this watchdog patch is independent of the variant AFAICS, or?

I am going to test your watchdog changes with a later silicon version later today and I expect no problems. Regards, Steve ^ permalink raw reply [flat|nested] 8+ messages in thread

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!

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 ^ permalink raw reply [flat|nested] 8+ messages in thread
