Subject: [PATCH v5 00/20] arm64: sunxi: Initial Allwinner H616 SoC support

Hi,

this is a small update from v4, fixing some DT validation issues:
dtbs_check now comes back clean for me.
Also I dropped USB support for now. It turns out that this is more messy
than we thought: it only works if all four USB controllers are enabled
(and not just some PHYs). That smells like some shared reset or clock
gate, but we haven't found the culprit yet. Also the BSP source suggests
that there is a "hardware design issue" that requires some PHY tune
register to be programmed, so we probably need more code anyway.
I also dropped the DT node for the second EMAC, as this is mostly
untested at this point.

Changelog below. Based on the (updated) sunxi/for-next branch.

I was hoping that at least the clock and AXP patches (01/20-06/20) could
make it into 5.12 still? That would allow booting boards from SD card.
Patch 08/20 would enable Ethernet.
U-Boot support is now merged into its master tree.

Thanks!
Andre

==================
This series gathers patches to support the Allwinner H616 SoC. This is
a rather uninspired SoC (Quad-A53 with the usual peripherals), but
allows for some cheap development boards and TV boxes, and supports
up to 4GB of DRAM.

Various DT binding patches are sprinkled throughout the series, to add
the new compatible names right before they are used.
Patch 2 and 3 add clock support. For the -R clock this is shared with
the H6 code, as the clocks are identical, with the H616 just having
fewer of them. The main clocks are different enough to warrant a separate
file.
Patches 5 and 6 teach the AXP MFD driver to get along without having an
interrupt, as the missing NMI pin on the H616 leads to some boards not
having the AXP IRQ line connected.
Patch 8 and 16 add some tweaks to the syscon and EMAC driver, to deal
with the second EMAC clock used for the second Ethernet controller.
This is somewhat optional for the current .dts, as this doesn't use
the second EMAC.

The remaining patches add DT bindings, which just add the new compatible
string along with an existing name as a fallback string.
Eventually we get the .dtsi for the SoC in patch 19, and the .dts for
the OrangePi Zero2 board[1] in the last patch.

We have U-Boot and Trusted-Firmware support in a working state, booting
via FEL or SD card and even TFTPing kernels work already [2][3].
The U-Boot patches are already merged into the mainline repository.

Many thanks to Jernej for his tremendous help on this, also for the
awesome input and help from the #linux-sunxi Freenode channel.

Happy reviewing!

Cheers,

Subject: [PATCH v5 06/20] mfd: axp20x: Allow AXP chips without interrupt lines

Currently the AXP chip requires to have its IRQ line connected to some
interrupt controller, and will fail probing when this is not the case.

On a new Allwinner SoC (H616) there is no NMI pin anymore, and at
least one board does not connect the AXP's IRQ pin to anything else,
so the interrupt functionality of the AXP chip is simply not available.

Check whether the interrupt line number returned by the platform code is
valid, before trying to register the irqchip. If not, we skip this
registration, to avoid the driver to bail out completely.

Subject: [PATCH v5 05/20] Input: axp20x-pek: Bail out if AXP has no interrupt line connected

On at least one board (Orangepi Zero2) the AXP305 PMIC does not have its
interrupt line connected to the CPU (mostly because the H616 SoC does
not feature an NMI pin anymore).
After allowing the AXP driver to proceed without an "interrupts"
property [1], the axp20x-pek driver crashes with a NULL pointer
dereference (see below).

Check for the regmap_irqc member to be not NULL before proceeding with
probe. This gets normally filled by the call to regmap_add_irq_chip(),
which we allow to skip now, when the DT node lacks an interrupt
property.

Subject: [PATCH v5 07/20] dt-bindings: sram: sunxi-sram: Add H616 compatible string

The H616 adds a second EMAC clock register. We don't know about the
exact SRAM properties yet, so this gets omitted for now.

Subject: [PATCH v5 17/20] phy: sun4i-usb: Rework HCI PHY (aka. "pmu_unk1") handling

As Icenowy pointed out, newer manuals (starting with H6) actually
document the register block at offset 0x800 as "HCI controller and PHY
interface", also describe the bits in our "PMU_UNK1" register.
Let's put proper names to those "unknown" variables and symbols.

While we are at it, generalise the existing code by allowing a bitmap
of bits to clear, to cover newer SoCs: The A100 and H616 use a different
bit for the SIDDQ control.

Subject: [PATCH v5 16/20] net: stmmac: dwmac-sun8i: Prepare for second EMAC clock register

The Allwinner H616 SoC has two EMAC controllers, with the second one
being tied to the internal PHY, but also using a separate EMAC clock
register.

To tell the driver about which clock register to use, we add a parameter
to our syscon phandle. The driver will use this value as an index into
the regmap, so that we can address more than the first register, if
needed.

Subject: [PATCH v5 18/20] arm64: dts: allwinner: Add Allwinner H616 .dtsi file

This (relatively) new SoC is similar to the H6, but drops the (broken)
PCIe support and the USB 3.0 controller. It also gets the management
controller removed, which in turn removes *some*, but not all of the
devices formerly dedicated to the ARISC (CPUS).
There does not seem to be an extra interrupt controller anymore, also
it lacks the corresponding NMI pin, so no interrupts for the PMIC.

Subject: [PATCH v5 11/20] dt-bindings: media: IR: Add H616 IR compatible string

Add the obvious compatible name to the existing IR binding, and pair
it with the existing A31 fallback compatible string, as the devices
are compatible.

On the way use enums to group all compatible devices together.

Subject: [PATCH v5 12/20] dt-bindings: rtc: sun6i: Add H616 compatible string

Add the obvious compatible name to the existing RTC binding, and pair
it with the existing H6 fallback compatible string, as the devices are
compatible.

Subject: [PATCH v5 03/20] clk: sunxi-ng: Add support for the Allwinner H616 CCU

While the clocks are fairly similar to the H6, many differ in tiny
details, so a separate clock driver seems indicated.

Derived from the H6 clock driver, and adjusted according to the manual.

Subject: [PATCH v5 04/20] dt-bindings: mfd: axp20x: Add AXP305 compatible (plus optional IRQ)

The AXP305 PMIC used in AXP805 seems to be fully compatible to the
AXP805 PMIC, so add the proper chain of compatible strings.

Also at least on one board (Orangepi Zero2) there is no interrupt line
connected to the CPU, so make the "interrupts" property optional.

No, the driver is not the right place to patch this; regmap should be
fixed so it does not crash instead.

I am not sure this is the right approach, those regmap functions look
more like an internal interface to me, with lots of wrapper functions
happily dereferencing pointers and reaching into structs. Moving
NULL checks into those does not sound like the right thing. CC:ing Mark
for more opinions on this.

A more general solution would be to not instantiate this driver here
at all, when we don't have an interrupt line.
However at the moment the AXP MFD driver uses a const struct to hold
all MFD cells, so there is no easy way of omitting the power key
device dynamically. And even then it would hard code the requirement
for an interrupt into the MFD driver, when this could be considered an
implementation detail of the axp20x-pek driver.

That's why I came up with this patch here, which was the easiest and
cleanest: This driver *requires* a valid regmap_irqc, so it should
verify this at probe time, kind of like a normal driver would bail out
if no IRQ line could be reserved.

Let me know what you think!

Cheers,
Andre

It sounds like you're trying to register an IRQ chip with a somehow
bogus configuration?

Without having seen the actual issue if you're trying to register an
interrupt controller with a known broken hardware configuration that
does seem like something the caller just shouldn't be doing, it's not
something that's going to transiently happen at runtime and we're very
much trusting that the caller got things right.

Quick background: Those AXP PMICs have an IRQ pin, that was always
connected to the NMI pin on Allwinner SoCs. This was used for the power
button GPIO interrupt. Now the H616 does not have this pin anymore, and
the board does not use a GPIO either.
I patched the AXP MFD driver [1] to skip the regmap-irq creation when no
interrupts DT property was found, but this NULL pointer now
understandably confuses the -pek driver, and leads to this crash:

http://lists.infradead.org/pipermail/linux-arm-kernel/2021-January/634969.html

Hence I wanted to plug this hole, which seems useful regardless of this
particular issue.

I will have a look at how much this takes.

The driver code here looks pretty confused. It appears to be looking up
the interrupt to use from a resource (which is what I'd expect for a MFD
child) then for reasons I can't fathom trying to pass that resource into
regmap_irq_get_virq() which is at best going to just return the value
that was passed in but may potentially end up just returning a random
interrupt other than the one that was asked for since we're passing in a
global interrupt number rather than a controller relative one. I really
can't tell what's supposed to be going on there. A driver should either
use resources or it should use regmap_irq_get_virq(), using both is a
bug.

The MFD for this device is also just plain buggy in that it is providing
IRQ resources to the children when there is in fact no support for the
interrupts on the device in the system. This means that the MFD core
sees that it has no interrupt domain, assumes that those interrupt
resources are in fact absolute interrupt numbers and passes them
straight through to the children. This means that the children will
just be requesting random interrupts in the system which may actually
exist and be requestable which probably isn't going to end well. When
there is no interrupt controller the parent should not be trying to
supply interrupt resources to the children at all.

After close lookup I would disagree with this observation. Major difference is
that H616 doesn't support usage of external 32768 Hz oscillator. It uses 24
MHz oscillator with divider for that case. Due to that change, whole logic for
external oscillator should go out. Additionally, this logic overwrites default
value in LOSC_CTRL register, which is not nice (there is no documentation for
those bits).

Thanks for the heads up, and I wonder if there is more to that. From
comparing the RTC documentation, I wonder if we should actually have
incoming clocks in the bindings (the crystals / external clock sources
with 32KHz, 16MHz, 24MHz). Then we could actually model which crystals
the board provides. It seems like the H6 made the 32KHz OSC optional,
and the H616 simply doesn't support it anymore - at the very least I
don't see any X32K pins anymore.

But more importantly: looking more closely (I only skimmed over the
register summary back then) the actual RTC registers are different:
the H616 encodes a linear day number (vs. a broken-down D-M-Y), also the
time-of-day register is different.

So we definitely need a driver update, and hence need to drop this
patch.

Andre

axp305? axp803 is used with A64 IIRC.

Oh, well spotted. This AXP naming already confused me when they were
all called 80x, now using 30x gave me the rest ;-)

I don't normally (yet) ask for schema conversions on compatible
additions, but this is one of the few remaining compatibles with no
schema for allwinner. So a conversion here would be nice. BTW, dtschema
now has a better check for this (-m option) without the false positives.
I plan to turn on the option soon (doesn't matter for dtbs as they all
have lots of warnings, but bindings also get warnings).

Either way,
