Hi All,

This patch series describes i2c, iic, mmc0, sdhi, sata, AVB, apmu and
RWDT on R8A7742 SoC.

Cheers,
Prabhakar

Add the I2C[0-3] and IIC[0-3] devices nodes to the R8A7742 device tree.

Automatic transmission for PMIC control is not available on IIC3 hence
compatible string "renesas,rcar-gen2-iic" and "renesas,rmobile-iic" is
not added to iic3 node.

Makes sense.

However, both versions (with and without automatic transmission) are
described with the same "renesas,iic-r8a7742" compatible. Is it possible
to detect the reduced variant at runtime somehow?

My concern is that the peculiarity of this SoC might be forgotten if we
describe it like this and ever add "automatic transmissions" somewhen.

Dunno if patches need to be this fine-grained (e.g. group all simple additions
like this in one patch) but still:

Thank you for review.

Its similar to as seen on Rcar-H2 where just the A15 cores are up and
A7 cores fail to boot. Attached is the boot log where reboot works as
expected with all A15 core up. Although I have tested the internal
release based on 3.10 where all the cores are up which used bootarg
apmu=multicluster (https://patchwork.kernel.org/patch/3948791/). So
there is some work involved to get all the A7's up and running.


Cheers,

Well, I guess reading from a register which is supposed to not be there
on the modified IP core is too hackish.

Leaves us with a seperate compatible entry for it?

Sounds good enough to me. Thanks for the heads up!

Sounds okay to me, how about "renesas,iic-no-dvfs" ? So that this
could be used on all the SoC's which don't support DVFS.

Well, the feature missing is used for DVFS, but its name is "automatic
transmission". So, I'd rather suggest "-no-auto" as suffix. Also, there
are already quite some IIC variants out there, so plain "iic" won't
catch them all. My suggestion would be "renesas,rcar-gen2-iic-no-auto".

All the best,

   Wolfram

Hence if we really need that (see below), we need a quirk based on compatible
value + base address.

According to the Hardware User's Manual Rev. 1.00, the registers do exist
on all RZ/G1, except for RZ/G1E (see below).

   "(automatic transmission can be used as a hardware function, but this is
    not meaningful for actual use cases)."

(whatever that comment may mean?)

> Leaves us with a seperate compatible entry for it?

On R-Car E3 and RZ/G2E, which have a single IIC instance, we
handled that by:

        The r8a77990 (R-Car E3) and r8a774c0 (RZ/G2E)
        controllers are not considered compatible with
        "renesas,rcar-gen3-iic" or "renesas,rmobile-iic"
        due to the absence of automatic transmission registers.

On R-Car E2 and RZ/G1E, we forgot, and used both SoC-specific and
family-specific compatible values.

Indeed.  Commit c16a854e4463078a ("mmc: renesas_sdhi: Add r8a7743/5
support") predated commit d6dc425ae595e140 ("mmc: renesas_sdhi:

Thanks for chiming in, Sergei!

Yeah. I know it's missing for a few other SoCs, too.

Strange comment, in deed. Given the paragraph before, I would guess Gen1
maybe had a "fitting" PMIC where SoC/PMIC handled DVFS kind of magically
with this automatic transfer feature? And Gen2 has not.

From a "describe the HW" point of view, this still makes sense to me.
Although, it is unlikely we will add support for the automatic
transmission feature (maybe famous last words).

Okay, but we can fix DTs when they have bugs, or?

We can.  But we also have to consider DT backwards compatibility: i.e.
using an old DTB with a future kernel implementing the automatic
transmission feature.

Fortunately R-Car E2 and RZ/G1E have SoC-specific compatible values,
so we can easily blacklist it in the driver based on that.
Blacklisting the last instance on the other SoCs is uglier, as it needs a
quirk that checks both the SoC-compatible value and the absence of the
generic compatible value. But it can still be done.

i.e. will queue in renesas-devel for v5.9.

Meanwhile in the DT tree, converting this schema landed. Can you prepare

Yes, I'm aware of that. I was hoping for a better commit message which
