[PATCH 0/3] ARM: dts: the dts support for rk3288 firefly reload

[PATCH 0/3] ARM: dts: the dts support for rk3288 firefly reload

[ayaka]

The rk3288 firefly reload  is a Rockchip RK3288 based board be found by
core board and main board. The regulators are connected in a different
way to the previous version of firefly boards, it is necessary to
move some common code to uncommon place.

I only tested the ethernet and confirmed that works.

[PATCH 1/3] ARM: dts: add label leds for rk3288-firefly.dtsi

[ayaka]

The connected leds are different in firefly and firefly reload.
Adding this label making it is possible to add more leds.

[PATCH 2/3] ARM: dts: move regulator settings from common to specifics

[ayaka]

The regulator settings are the same in the firefly beta and
firefly. But the firefly reload is different. I remove
the difference part from the common header dtsi, but remained those
common one to keep references.

applies to all 3 patches: we require real names both in the patch/mail from 
as well as the Signed-off-by line, see [0] at number 11. To my untrained eye 
the name given doesn't look like a real name, please correct me if I'm 
wrong.

Not 100% sure, but I guess this does not need to be duplicated.
The supply is named vcc_lan in all board revisions only the supplying 
regulator seems different, so it should be enough to point the vcc_lan 
phandle to the correct regulator in the relevant file, but the gmac 
assignment could stay in the main file?

the phandle name is to generic, as this is part of the act8846 and not 
something generic. So please name the phandle act8846_regulators / 
act8846_regs or so.

[PATCH 2/3] ARM: dts: move regulator settings from common to specifics

[Randy Li]

The regulator settings are the same in the firefly beta and
firefly release version. But the firefly reload is different.
I remove the different part from the common header dtsi file,
but remained those common one to keep references.

But I can't have two label in two different place.

[PATCH 0/3] ARM: dts: the dts support for rk3288 firefly reload

[Randy Li]

The rk3288 firefly reload  is a Rockchip RK3288 based board be found by
core board and main board. The regulators are connected in a different
way to the previous version of firefly boards, it is necessary to
move some common code to uncommon place.

I only tested the ethernet and confirmed that works.
The usb in this board won't caused by the bugs in the driver.

This version follow the suggests from Heiko Stuebner,
except the duplicated supply name problem, I don't think
it could be fixed in that way.

The connected leds are different in firefly release version
and firefly reload.
Adding this label making it is possible to add more leds.

[PATCH 2/3] ARM: dts: move regulator settings from common to specifics

[Randy Li]

The regulator settings are the same in the firefly beta and
firefly release version. But the firefly reload is different.
I remove the different part from the common header dtsi file,
but remained those common one to keep references.

I've now had a chance to look at that reload board on the firefly site.
Firefly also is the company name, so a board named that way is not 
necessarily a "variant" :-) .

And looking at the "reload" board this definitly seems to be a very 
different product with it being a system-on-module+baseboard design with 
additional peripherals like that sata bridge, camera interfaces and probably 
more.

As you might've seen, most Rockchip boards are based on some reference-
design, so are similar in a big part of their core layout.
So, looking at the vastly different product the reload is, I'd really like 
to have a separate dts for the reload, to not run into more confusing 
differences later on.

Also, when adding a new board, please also add an entry to 
Documentation/devicetree/bindingd/arm/rockchip.txt


Thanks
Heiko

sata bridge is just a SATA to usb bridge and the "reload" bring back the 
DVP camera interface and
a HDMI rx chip connected to the other MIPI camera interface.

Yes, from the evb. But the even the main board of evb in rockchip 
company have at lease 3 versions
as I known.
Also the evb is found by power board, main board and core board.

The main problem is that power connections are different. That is why I 
decide to make a
separate dts. If the kernel introduce the override dts, I could have a 
better way to implement
it.

I would send a patch set in a few days.

there are always more things to control (reset pins, regulators) and the usb 
subsystem is currently in the process of getting support for such "embedded" 
uses.

Just to make sure we're not talking about different things. This was meant 
to illustrate that even though core layouts often look similar we should not 
try to connect different product board files unnecessarily, as the small 
differences will make everything more complicated.

The "reload" definitly is a completely different product that only shares 
the manufacturer (firefly) and the soc (rk3288) with the other product and 
as I wrote should get its own independent dts file.


If anything you could do a split into a reload-core dtsi for the system-on-
module part and a baseboard dts that includes that (something like what is 
done for rk3288-rock2).

no problem, always nice to have more people play with Rockchip stuff on a 
mainline kernel :-)

[PATCH] ARM: dts: the dts support for rk3288 firefly reload

[Randy Li]

This version is split into a reload core dtsi for the SoC module
part and a baseboard dts for the reload baseboard. Thanks to
the Heiko's advise.

[PATCH] ARM: dts: add rk3288-firefly-reload

[Randy Li]

The Firefly RK3288 Reload is a combination Firefly rk3288 core board
with the Reload baseboard. Add a dtsi for the Firefly rk3288 core
which can be included into the dts for the various baseboards
in the future and dts for Reload base board.

Currently supported are serial console, wired networking, eMMC and
SD storage, SPFIF, IR receiver, LEDs, SDIO wifi and USB. But only
the OTG could work on the host mode now, the other USB host can't
work now, additional patches are required.

looks mostly good, two small issues below. While I could replace the
io-domain node with the newer variant myself, the licensing issue will
require a resend anyway.

Please also carry over Rob's Ack in your resend as well.

please allow licensing under GPL and MIT licenses ... see license headers
of the other Rockchip boards. Same for the dts file below.

io-domains are now a sub-device of the GRF, see

Re: [PATCH v2] ARM: dts: add rk3288-firefly-reload

[Randy Li]

Hi Heiko:

I use GPLv2 because of it looks more shorter, anyway I am back to allow
X11 now. The modification request of io-domain have been included.

Thank you for reviewing.

[PATCH] ARM: dts: add rk3288-firefly-reload

[Randy Li]

The Firefly RK3288 Reload is a combination Firefly rk3288 core board
with the Reload baseboard. Add a dtsi for the Firefly rk3288 core
which can be included into the dts for the various baseboards
in the future and dts for Reload base board.

Currently supported are serial console, wired networking, eMMC and
SD storage, SPFIF, IR receiver, LEDs, SDIO wifi and USB. But only
the OTG could work on the host mode now, the other USB host can't
work now, additional patches are required.

applied [0], after some minor reordering - please double check.

Also, while the branch is named 4.8 this will only go into 4.9, as the merge-
window supposedly opens on the weekend.

Sorry for the noise here:), but I find there is some mmc stuff
which confuse me. Maybe Randy could elaborate more?

Your sdmmc claims to support UHS-I mode like sd-uhs-sdr104, etc, which
will ask dw_mmc to switch vqmmc from 3V3 to 1V8 after sending CMD11.

But the vqmmc is vccio_sd which is fixed as 3V3? :)

so far we have only been able to achieve UHS speeds on devices based on the 
rk808 pmic (I had sucess on veyron and popmetal). The act8846-based boards 
seem to have some issue when trying to do the switch to 1.8V, resulting in 
mmc errors and the mmc-core switching back to 3.3V.

I think this might be caused by a bug in the act8846 driver or some dts 
mistake. But so far nobody had the time and enthusiasm to investigate :-)

Hi all,
sdcard-supply must be specifed  in io-domains node to enable uhs.

io-domains {
compatible = "rockchip,rk3288-io-voltage-domain";
rockchip,grf = <&grf>;
sdcard-supply = <&vccio_sd>;
wifi-supply = <&vcc_18>;
};

well，it has already been added....

The root cause is not act8846. Firefly have a bug with sdmmc and it

Yes, Jacob is right. Those high speed options need the voltage down to 1.8v. They should be removed.

Thanks Jacob for pointing out this issue - I was always wondering why it 
wasn't working :-) .

Randy, can you provide a follow-up patch that removes these excess properties 
please?

I will send a patch in weekend. I need some time to confirm whether
the sdio wifi would meet the same problem in firefly reload.
I found those patches are not been merged yet, should I just send
a new version or just a patch remove those incorrect excess properties?

I double check the regulators settings in dts after the sdcard issue,
I found I didn't make them match the hardware of firefly reload board.

that looks wrong. vccio_sd is still the vqmmc supply in the schematics even 
though we don't want to switch to 1.8V . But that regulator should still be 
controllable without needing a regulator-always-on in the future.

I think the vccio_sd is just the one connected to the io_domains, but 
the voltage source for the
pull up register is not vccio_sd but vcc_io.

vqmmc-supply is the so called io-voltage according to the code and also the 
jedec spec (VCCQ). And the sdmmc0_vdd that vccio_sd is connected to is exactly 
that ... according to the rk3288 datasheet the "SDMMC0 Digital IO Power 
Supply", so that connection is not only meaningful for the iodomains, but _is_ 
an actual supply and if you turn off vccio_sd, you probably won't get any 
sdmmc transfers at all ;-) .

So yes, due to the resistor misheap vccio_sd should stay limited to 3.3V, but 
its connection as vqmmc should stay.

In the future, please try to base your patches either on the correct dts 
branch in my repo [0] or simply on linux-next which does contain these too,
as I did reorder some things when applying your initial firefly-reload patch.

[PATCH 2/2] ARM: dts: rockchip: add missing regulators for firefly reload board

[Randy Li]

There are many regulators are missed in previous commit, this
commit complete most of them. It also fix some mistakes in the
regulator properties. The VDD_10(REG10) and VCC_18(REG11) had better
to keep in always-on state, as it is used as the USB PHY supply,
corretly we have no way to assign power supply to a USB PHY.
The VCCA_33(REG8) should be enabled or the GMAC won't work.

It also fix the wrong properties for audio in io-domains, the supply
connected to APIO4_VDD is different to firefly release version.

[PATCH 2/2] ARM: dts: rockchip: add missing regulators for firefly reload board

[Randy Li]

There are many regulators are missed in previous commit, this
commit complete most of them. It also fix some mistakes in the
regulator properties.

It also fix the wrong properties for audio in io-domains,  the supply
connected to APIO4_VDD is different to firefly release version.
