[PATCH 1/7] ARM: dts: s5pv210: Split memory nodes to match spec

[PATCH 1/7] ARM: dts: s5pv210: Split memory nodes to match spec

[Jonathan Bakker]

Memory nodes should only have a singular reg property in them, so
split the memory nodes such that there is only per node.

0x40000000 to 0x58000000 is continues, so I wonder why it is split? Look
at Aquila DTS.

Yes, it was split in the vendor kernel as well [1], and that's been continued along
here.  I personally don't see a reason to keep it split, but there might be something
I'm not aware of.

[PATCH 2/7] ARM: dts: s5pv210: Adjust I2S entries to match spec

[Jonathan Bakker]

Based on the device tree spec, clocks should be ordered tx/rx.
Re-order from rx/tx to avoid warnings when running make dtbs_check

Additionally, the number of #sound-dai-cells should be 1, not 0

In order to correct this, drop the spi-cs-high from the panel SPI device.

I guess they wanted maybe to express the physical banks. Fine with me.
Just your explanation is not entirely correct:
> Memory nodes should only have a singular reg property in them,
one reg but it can have multiple items. Why do think multiple reg items
is not allowed?

Except that fix that's the same commit as here:
https://lore.kernel.org/all/20200907161141.31034-26-krzk@kernel.org/
so just extend it.

sound-dai-cells should go to a separate commit. But are you sure they
are correct? The Fascinate 4G seems to be using them as cells=0.

Such fixes should be either a separate patchset or put them first in the

I was basing it off of this warning when running make dtbs_check

rch/arm/boot/dts/s5pv210-aquila.dt.yaml: /: memory@30000000:reg:0: [805306368, 83886080, 1073741824, 402653184] is too long
	From schema: /home/jon/.local/lib/python3.7/site-packages/dtschema/schemas/reg.yaml

and this solved the warning, booted, and I still had the correct
amount of memory.

Would

	memory@30000000 {
		device_type = "memory";
		reg = <0x30000000 0x05000000>,
			<0x40000000 0x18000000>;
	};

be equally correct?  (untested).

Jonathan

The charger manager code needs a passive cooling device, so that's
why this is present here.

Thanks, I missed the deprecation notice in the binding file.

What would be the better way of creating a functional charging system?
A new device-specific driver?  Userspace monitoring of temperature/connected
device and extensions to the max8998 driver for enabling/disabling/configuring
charging via the power supply subsystem instead of the regulator subsystem?
Something else?

The way I understand the charging system, there is

- The fuelgauge (max17042)
- The max8998 charger portion, including the ability to vary the current
- The thermistor for checking battery temperature
- The FSA9480 to determine what sort of cable is connected

Thanks,
Jonathan

Thanks, I'd totally forgotten about this series from the past.  I'll re-test
those commits and submit your copies of them in v2 if that's OK with you and
that they're confirmed functional?

I am not sure, but maybe you could use charger-manager, just configure
it from user-space (or add such features). Better ask power supply
maintainer. But anyway charger-manager is mostly abandoned. I don't
think anyone develops it.

Enabling charging via regulators was done only for some drivers, I think
for charger-manager. I don't think it is the recommended way now.

Everything should be controlled rather via power supply from user-space.

How postmarketos or lineageos are doing it?

My dma fixes change lacked this aries fix. The sound-dai-cells needed
more rethinking.

Yeah, I made it so that it could be probed a year and a half ago, but
there's been very little use of it - there's no in-tree users of it that
I can tell.

It's quite varied, but I can't find any examples of a userspace
daemon watching temperature/connection type, although it should be
fairly simple to implement.  A few examples:

- Maemo Leste uses a plugin to their MCE daemon to shutdown on low battery
- postmarketOS uses whatever is in kernel and whatever the DE provides to shutdown
on low battery
 - It also has a power stats collecting software, IIRC, although this might be DE
specific
- LineageOS/Android has healthd, but this appears to be more for gathering stats

In terms of in-tree examples, there's quite the variety:

- The AB8500 driver (used in some STE phones) is fairly similar situation,
with separate fuelgauge, charger and temperature drivers bound together by
an "algorithm" driver that checks temperatures and what is connected (very
similar to charger-manager, but specific to that HW).
- Nokia N900 has temperature reading integrated, but no shutoff
- Pinephone/Pinetab appears to have separate USB/AC charger drivers and
a battery driver, but no temperature monitoring.

So it rather looks like there's no consensus.  I guess I'll do some more research
and drop this patch for now.

Thanks,
Jonathan

Hi Jonathan,

Any plans for checking/fixing/testing and resending the sound-dai-cells

Oops, I forgot about this again...  Unfortunately, I don't really have the time
