[PATCH 8/8] arm64: dts: rockchip: RockPro64: enable wifi module at sdio0

[PATCH 8/8] arm64: dts: rockchip: RockPro64: enable wifi module at sdio0

[Soeren Moch]

RockPro64 supports an Ampak AP6359SA based wifi/bt combo module.
The BCM4359/9 wifi controller in this module is connected to sdio0,
enable this interface.

Signed-off-by: Soeren Moch <smoch@web.de>
---
Not sure where to place exactly the sdio0 node in the dts because
existing sd nodes are not sorted alphabetically.

This last patch in this brcmfmac patch series probably should be picked
up by Heiko independently of the rest of this series. It was sent together
to show how this brcmfmac extension for 4359-sdio support with RSDB is
used and tested.

node placement looks good so I can apply it, just a general questions
I only got patch 8/8 are patches 1-7 relevant for this one and what are they?

Thanks

Patches 1-7 are the patches to support the BCM4359 chipset with SDIO
interface in the linux brcmfmac net-wireless driver, see [1].

So this patch series has 2 parts:
patches 1-7: add support for the wifi chipset in the wireless driver,
this has to go through net-wireless
patch 8: enable the wifi module with this chipset on RockPro64, this patch

If this was confusing, what would be the ideal way to post such series?

Thanks,
Soeren

Thanks for the clarification :-) .

As patch 8 "only" does the core sdio node, it doesn't really depend on the
earlier ones and you can submit any uart-hooks for bluetooth once the
other patches land I guess.


> If this was confusing, what would be the ideal way to post such series?

I think every maintainer has some slightly different perspective on this,
but personally I like getting the whole series to follow the discussion but
also to just see when the driver-side changes get merged, as the dts-parts
need to wait for that in a lot of cases.

FWIW I prefer the same as Heiko. If I don't see all the patches in the
patchset I start worrying if patchwork lost them, or something, and then
it takes more time from me to investigate what happened. So I strongly
recommend sending the whole series to everyone as it saves time.

The uart part for bluetooth already is in: uart0.
However, I haven't tested if it really works.

OK, thanks.
I will add you for the whole series when sending a v2.

In the new world there is now also a way to actually hook the bt-uart to
the wifi driver without userspace intervention, and you might want to hook
up the interrupt as well for sdio? For example look at the rock960:

sdio-interrupt: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm64/boot/dts/rockchip/rk3399-rock960.dtsi#n510

Thanks for your explanation.
I will keep this in mind for future submissions.
