I think this patch misses some recipients because neither
the watchdog maintainers nor the watchdog list is included.

We'll need for them to at least Ack this patch, so they'll
need to be included. Please check your scripts/get_maintainer.pl
call


Thanks

I don't think that will have worked.

Ideally can you include Conor's Ack and resend only the watchdog binding
patch to the watchdog maintainers (and lists and me too please) .

Because just adding more people to a reply probably won't tell them
that some action is expected.

Thanks for your info. It's my mistake. I will resend the watchdog patch 
alone.

just for my understanding, does this mean that you expect this change

No preference, just making sure I understand :-)

i was actually wondering how this was going to get applied. I guess that
if you are planning to take the rest, you can also apply this one.

so we were both wondering the same thing :-) .

For some other watchdog binding Guenter suggested the binding patch
to go with the rest, so I wanted to make sure your Ack meant the same.

But of course I'm also fine/happy with you just picking up this rtc
binding patch for the rtc tree :-)

[PATCH v3 6/6] ARM: dts: rockchip: Add Relfor Saib board

[Karthikeyan Krishnasamy]

Saib is an consumer electronics board from Relfor labs
Features:
    - Rockchip RV1109
    - 1GB DDR4
    - 4GB eMMC
    - Realtek RTL8821CS Wi-Fi/BT
    - IR transmitter/receiver
    - RV3028 RTC
    - Switch
    - User leds

Add support for it.
