[PATCH v6 0/9] AXP803 PMIC support for Pine64

[PATCH v6 0/9] AXP803 PMIC support for Pine64

[Icenowy Zheng]

The Pine64 (including Pine64+) boards have an AXP803 PMIC, which is a PMIC
similar to AXP288, but tweaked to use with Allwinner SoCs rather than Intel
tablets (with DCIN and Vbus re-splitted like other AXP PMICs, and RSB bus
support added).

This patchset adds support for it and enabled it in Pine64 device tree.

Some parts of this patchset is already applied, including basical AXP803
MFD code and A64 RSB device node.

Thus this patchset is now still two parts, but a bit different to older
revisions:

- Part1: from PATCH 1/9 to PATCH 4/9, which focus on enabling AXP803 in the
  device tree: the R_INTC interrupt controller (for the NMI line, which is
  connected to AXP803 on Pine64), and finally the basical AXP803 node.
- Part2: from PATCH 5/9 to PATCH 9/9, which are enabling the regulator
  function of the AXP803 PMIC. Finally Wi-Fi function is added
  as a usage of regulators function.

PATCH 1 adds device tree binding of A64 R_INTC.

PATCH 2 really adds support for A64 R_INTC in NMI driver.

PATCH 3 adds R_INTC node in A64 device tree.

PATCH 4 adds AXP803 node to the Pine64 device tree by using already
applied drivers/bindings.

PATCH 5 adds support for AXP803 regulators in AXP20x regulatoe driver.
(The binding is already applied)

PATCH 6 enables the AXP803 regulator cell in MFD driver.

PATCH 7 adds a DTSI file for AXP803, like other older AXP PMICs.

PATCH 8 enables AXP803 regulators in Pine64 device tree.

PATCH 9 enables Wi-Fi for Pine64.

[PATCH v6 1/9] irqchip/sunxi-nmi: add A64 R_INTC to the binding doc

[Icenowy Zheng]

The A31 NMI driver seems to be using wrong base address.

As we're going to convert to use a correct NMI base address (and
correctly name it to R_INTC as the datasheet suggests), add a new
compatible string for the "correct" R_INTC, which we will use for A64
SoC.

[PATCH v6 9/9] arm64: allwinner: a64: enable Wi-Fi for Pine64

[Icenowy Zheng]

The Wi-Fi module of Pine64 is powered via DLDO4 and ELDO1 (the latter
one provides I/O voltage).

Add device node for it.

Although the Wi-Fi module is an external module which should be inserted
to a header, according to my personal talk with TL Lim, he does not want
this header to be used as GPIO (so it's with 2.0mm pitch, not 2.54mm as
other GPIO headers).

"csi-afvdd-dovdd"

This regulator provides power for the camera module's Auto Focus, if available,
and Digital i/O parts of the sensor module. Hence the names of the rails.

This should probably be "vcc-hdmi-dsi".

On the MIPI-LCD page of the schematics, it says this is connected to
VDD18, so it should be 1.8V.

2.8V for this one.

The patch looks OK, but given the module is removable, I think it should be
an overlay. The overlay would enable WiFi + Bluetooth, and all the
peripherals needed to connect them.

That way, if the module is not installed, we avoid confusing the user with
unused peripherals, and avoid having live voltage on an unoccupied header.

But as this header have specific usage, we will also confuse user
if it's not enabled as its target usage.

The name is OK. I'm just worried about the voltage. We don't want
users frying their display panel. They probably cost more than the
board itself.

For most of these SBCs, they are designed to work with the panels
they provide. Could you reach out to TL Lim and ask about the voltage
used? Or maybe dig it out of the FEX files?

Thanks

I think, before we have an official repository of device tree
overlays (either directly in torvalds/linux or maintained by
linux-sunxi), we shouldn't rely on device tree overlay
functionality.

I think I mentioned this before, but the Pine64 has DDR3L DRAM, which is
specified to run at 1.35V (1.36V with the 20mV granularity of the AXP).
The reset value is even (wrongly?) configured to 1.24V.

So is there any reason you set the voltage to 1.5V? Is that what the BSP
does? Or did you see any problems with 1.36V?

Cheers,
Andre.

And 1.35v cannot be accurately achieved by dcdc5 and it's a problem whether to use 1.34v or 1.36v ;-)

I just set it based on the schematics.

And 1.35v cannot be accurately achieved by dcdc5 and it's a problem whether to use 1.34v or 1.36v ;-)

The schematic puts this at a fixed 3.0V, so why the range here? Are we
expected to tune the voltage of the PLLs?

I wouldn't trust the schematics too much. They are rather generic, see
the Ethernet page, for instance, showing *different* PHYs, not just the
ones used.
For the DRAM the Pine64 schematic does not even tell the DRAM chip used,
the name under the chip is just describing the package.

> And 1.35v cannot be accurately achieved by dcdc5 and it's a problem whether to use 1.34v or 1.36v ;-)

Well, as I wrote above, 1.36V is the voltage to go with. I think 10mV
more is well within the tolerance ;-)

If you stick to the schematic, this should be 2.8V.

The schematic lists 1.2V/1.5V/1.8V here, so should we have a range?

Why do we need to turn this on? Upstream firmware does not use the
arisc, so it can stay off.
Also in general I think Linux should not tinker with the management
processor at all.

Cheers,
Andre.

I wouldn't trust the schematics too much. They are rather generic, see
the Ethernet page, for instance, showing *different* PHYs, not just the
ones used.
For the DRAM the Pine64 schematic does not even tell the DRAM chip used,
the name under the chip is just describing the package.

Well, as I wrote above, 1.36V is the voltage to go with. I think 10mV
more is well within the tolerance ;-)

If you stick to the schematic, this should be 2.8V.

The schematic lists 1.2V/1.5V/1.8V here, so should we have a range?

Why do we need to turn this on? Upstream firmware does not use the
arisc, so it can stay off.
Also in general I think Linux should not tinker with the management
processor at all.

Cheers,
Andre.

No code either. In Allwinner's BSP, the interrupts for the PMICs go
through the (closed source) OpenRISC firmware, so there's no driver
for it in the kernel.

The registers line up with the old interrupt controller from the A10,
but it seems only the NMI interrupt is wired up.

This is a board specific overlay, and having some upstream repository
with all the possible combinations of SoC / daughter board is just not
realistic.

This should be shipped by the board vendors. RPi does that, the
beaglebone does that, the CHIP does that, surely, if it works for
them, it should work for you.

Is this OK? Or do you want Icenowy to respin a version with defines?

This, and the previous dt bindings patch, can be merged through whatever
tree irqchip drivers are merged through. Is that Jason's irqchip tree?

We're mostly waiting on this before merging the remaining device tree
changes.

Is this OK? Or do you want Icenowy to respin a version with defines?

This, and the previous dt bindings patch, can be merged through whatever
tree irqchip drivers are merged through. Is that Jason's irqchip tree?

We're mostly waiting on this before merging the remaining device tree
changes.

Ideally, I'd like to see some #defines, but given that the rest of the
file is already littered with hard-coded constants, you might as well do
the whole thing in a subsequent patch that I would merge with these two
patches.

I'll probably start pushing a branch with all the irqchip patches I've
collected at some point this week, for Thomas to take into 4.13.

Personally I think the values are self-explained (the variable
name) and used only once in this structure.

Making defines doesn't make the code more clear.

Personally I think the values are self-explained (the variable
name) and used only once in this structure.

Making defines doesn't make the code more clear.

That's where you're severely misguided. There is plenty of places in the
kernel where constants are used exactly once, and yet they have a
#define. And the reason for this is consistency. We don't deal with raw
values, we deal with named constants.

For you, this code is probably "write-only". Once it works, you'll never
go back to it. On the other hand, I get to maintain it and apply tree
wide changes as necessary. So if the code looks better *to me*, then
that's the way.

Normally these would describe the operating limits. We did this
in the past for most boards. I'm fine with fixing it to 3.0V
though.

This and avdd-csi really depends on the camera module used.
Maybe this should be left to an overlay.

I'm not sure, but I think at least one SoC had failed to work without
this powered on. If that is the case with the A64, then please leave
a comment saying so. Otherwise let it stay off.

Normally these would describe the operating limits. We did this
in the past for most boards. I'm fine with fixing it to 3.0V
though.
