[PATCH 0/6] ARM: rockchip: add initial support for rk3288

[Heiko Stübner]

This series adds the initial support for Rockchip rk3288 socs including
debug uart and devicetree files for the rk3288 evaluation board and
enables these boards to boot into an initramfs.

The series depends on an updated bootloader, which must start the timer
supplying the architected timer, which we will hopefully get in the next
days. It also depends on the patch
    "irqchip: gic: Add binding probe for ARM GIC400"
which will hopefully make it into the irqchip tree shortly.

[PATCH 2/6] ARM: rockchip: add debug uart used by rk3288

[Heiko Stübner]

The uarts on rk3288 are still compatible with the dw_8250, but located
at a different position and need DEBUG_UART_8250_WORD enabled.

[PATCH 3/6] ARM: Kconfig: set default gpio number for rockchip SoCs

[Heiko Stübner]

The new rk3288 needs a bigger gpio space, as it has 9 gpio banks.

[PATCH 6/6] ARM: dts: add rk3288 evaluation board

[Heiko Stübner]

There exist 2 variants using either the act8846 or rk808 as pmic, while the
rest of the board stays the same.

I haven't had time to do a full review, but I believe "soc" grouping
is not suggested.  See <http://patchwork.ozlabs.org/patch/323194/>

Unit address and reg should be the same. So this should be @500 (or reg 0, but
I don't think that's what you want).

As Doug mentioned, this isn't how we tend to do it any more (unless all devices
are physically on a bus, but then it should probably be named something else
than 'soc').

Most other platforms just call this "timer".

You should consider sorting entries based on address. That way, as you add new
entries over time, you'll have fewer conflicts than if they're all appended
instead.

"cru"? The node name is usually something labelling the type of device
("clock-controller")?

This should probably have a more precise compatible than _just_ syscon.

If the node doesn't have a reg entry then it shouldn't have a unit address.

Same here, you might want a more specific compatible as the higher-priority
one.

And again w.r.t compatible (I'll stop pointing them out now).

Hi,

This mostly looks good, with a couple of comments below.

This is slightly odd since you're defining the node just above, you could just
add the regulators right there.

No rk808 node? Or adding that once the driver is sorted out?

I'd recommend doing all of these with &-references instead to avoid having to
revisit this if/when the tree topography changes w.r.t. the 'soc' node. Also,
the gpio-keys should be on the top level.

It's slightly confusing that you didn't rename the old "DEBUG_RK3X_UART2".

Other than that:

Looks reasonable.  9 banks of 32 and that matches what's in the pinmux driver.

My problem is, to what :-) ... DEBUG_RK30_UART2 ?

RK30xx and RK31xx share these, but I guess at least the description should be 
adapted.

Yeah, trying to get these things right is an impossible task.  The
only thing I've ever seen that's sane is to just name things after the
first person in the code base to use them rather than trying to guess
ahead of time how similar products with similar marketing name will be
in the future.

...agree that even if you don't do the rename here that updating the
description would be nice.

Do we want to think about allowing someone to enable the A9-based
Rockchip SoCs separately than the A12-based ones?  I know it doesn't
hurt to have the arch timer code present on A9 SoCs (it will figure
things out at runtime), but people trying to build an A9-based system
might not want the extra code?

Anyway, I don't feel strongly about it, so:

I would have expected pinctrl for gpio0-5 to make sure pulls are

Since there's a strong concept of numbering of i2c busses on this SoC,
could you add aliases so that they show up nicely with the right ID?

Thanks!

I've also thought about this previously. Personally I would want to wait with 
introducing more complexity here until someone comes along with a use case.
Simply because we're talking about 7kb (stripped) for the arch-timer and 
machines with >1GB of memory.
So I'm not adverse to it, but I guess it will make more sense when more soc-
specific code lands - suspend stuff for example.


But I think we should be able to drop the dw_apb_timer altogether, as it stems 
from a time before I found the global-timer informations and all A9 SoCs 
should be able to use this one instead.

The other uarts also have rts/cts pins available, but optional it seems. So my 
idea was to let the boards decide which pins to use, instead of setting it in 
the soc-dtsi.

Other opinions? :-)

More likely, people using the A12-based system won't want the CACHE_L2X0
code (which adds an outer_cache.sync check to wmb()).
