[PATCH 0/5] Add GameForce Ace

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

Add support for the GameForce Ace. The GameForce Ace is an RK3588s
based gaming device with a 1080p display, touchscreen, hall effect
joysticks and triggers, 128GB of eMMC, 8GB or 12GB of RAM, WiFi 5,
and support for a 2242 NVME.

[PATCH 1/5] dt-bindings: power: supply: add dual-cell for cw2015

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

According to the datasheet for the cw2015 the device supports dual-cell
configurations. Add a new device tree property for this condition so
that the voltage values reported to userspace are correct.

[PATCH 2/5] power: supply: cw2015: Add support for dual-cell configurations

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

The Cellwise cw2015 datasheet reports that it can handle two cells
in a series configuration. Allow a device tree parameter to note
this condition so that the driver reports the correct voltage values
to userspace.

I found this:

http://www.cellwise-semi.com/Public/assests/menu/20230302/6400076806706.pdf

Which says:

  CW2015 can be used in 2 or more batteries connected in series, or
  several cells connected in parallel.

So dual-cell seems like a bad property name. Instead the number of
serial cells should be provided. This property is then not really
specific to the Cellwise fuel gauge and instead a property of the
battery pack (i.e. simple-battery.yaml).

Unfortunately there are no details in the document, but this looks
very fishy. Does it only measure the first cell and hope that the
other cells have the same voltage?

This (unmerged) series also applies to your problem to some degree:

It's conflicting information (which further confuses me). I see in that
datasheet it says 2 or more, whereas the datasheet found here says only
2 cells:

https://www.lestat.st/_media/informatique/projets/python-cw2015/cw2015-power-management-datasheet.pdf

But I agree in principle that we should be setting this as a property
of a simple-battery rather than a manufacturer specific parameter.

I think based on the application diagram it is in fact measuring the
cell voltage. That said, this ultimately boils down to a cosmetic thing
as not having this property simply means userspace sees the battery
voltage as 3.8v instead of 7.6v as is written on the side.

I think for simplification sake I will remove this from the series, add
a note to the device tree, and wait for the other battery series to get
pulled. When it gets pulled I'll request a device tree property so we
can add POWER_SUPPLY_PROP_NUMBER_OF_SERIAL_CELLS to the simple-battery
and then parse this value. Or if that series ends up getting abandoned
I can just add a quick and dirty new property like this.

Thank you,
Chris

With the cells being connected in serial, the voltage of both cells
can be different. There is not "the cell voltage". Instead there is
a voltage for cell 1 and a voltage for cell 2. In a perfect battery
they are the same, but in reality they are not. In the extreme case
one of the cells may be broken while the other is still fine. It
sounds as if this is just measuring the voltage from the first
cell and assumes the second cell has the same voltage.

Ideally the voltage on these platforms is not exposed via the normal
VOLTAGE property and instead uses a new property for telling
userspace the voltage for a single cell. The kernel simply does not
know the voltage of the whole battery pack.

FWIW this is the worst battery measurement system I've seen so far
if my understanding of the hardware design is correct.

Don't get me started, this whole stack is a nightmare. The battery
won't charge at all without a bq25703 driver (so this current DTS
basically has the device running while plugged in); and for some
reason the fcs,fc302 chip wants to go interrupt crazy if you're not
using a PD charger. Part of the reason of getting this upstreamed
is so I can have a common base for others to help me get this last
bit of nonsense sorted out. Displaying the correct voltage on the
battery however isn't critical, as the device will still report the
correct SoC and will even charge and function just fine when a driver
is in place for the bq25703. It's just the voltage reported in sysfs
will be wrong.

Thank you,

Please note that two facts should be considered here:

  - The GenBook schematic [1] clearly shows that the individual battery
    cells aren't exposed at its internal battery connector and, as a
    result, aren't available for individual cell voltage monitoring

  - The GenBook uses a CW2013 as it fuel gauge, [1] instead of CW2015
    as mentioned here a few times, but I haven't went through the CW2013
    datasheet(s) yet to see what are the actual differences between it
    and the CW2015

Ah, thanks for pointing to the schematics. So the fuel gauge can
only measure the voltage of the whole battery, but VCELL register
provides the voltage for 1 cell? What is the origin of the dual-cell
property? Was this something you came up with yourself when noticing
the wrong voltage?

Based on the above information my guess would be that CW2013 uses a
different voltage resolution than CW2015 for the VCELL register. The
datasheet for CW2015 says 14bit ADC with 305uV resolution. Maybe
the CW2013 simply uses a different ADC. Do you have the datasheet
for the chip?

I'm not sure where does the idea for the dual-cell property come from,
but please note that it wasn't me who invented it, so to speak. :)
I don't even have the required hardware to test and develop these 
patches
on, i.e. I don't have a CM5-based GenBook.

I've managed to find a few (seemingly a bit different) CW2013 
datasheets,
but as usual with CellWise, some of them may contain a bit confusing or
incomplete information.  I'd suggest that you wait for a couple of days
until I sift through the obtained datasheets, to save you from doing the
same. :)  Of course, I'll then send over the datasheet that seems 
correct
and the most complete to me.

I'll see to add support for CW2013 to the cw2015 driver, for which I
already have a couple of pending cleanup patches.

[PATCH 3/5] arm64: dts: rockchip: Pull up sdio pins on RK3588

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

When using an Ampak derived bcm43456 on an RK3588s based GameForce Ace
the WiFi failed to work properly until I set the SDIO pins from
pull-none to pull-up. This matches the vendor kernel located at [1].
I tested this then on an RK3588s based Indiedroid Nova and did not
observe any adverse effects.

As you're essentially duplicating the change by Alex Zhao it might be
nice to keep their authorship?

So, "From" + first Signed-off from Alex, then you add a
[adapted to pinctrl filename change]
Signed-off-by: Chris Morgan <macromorgan@hotmail.com>

below that.

Thank you, that was an oversight but I'll get it done in v2.

[PATCH 5/5] arm64: dts: rockchip: Add GameForce Ace

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

The GameForce Ace is a portable gaming device based on the Rockchip
RK3588s SoC.

The device contains the following hardware that is tested/working:
 - 128GB eMMC
 - SDMMC card slot
 - Ampak SDIO WiFi 5/BT
 - NVME 2242 socket
 - 8 or 12GB of RAM
 - Goodix based touchscreen
 - Stereo speakers, internal microphone, and TRRS headphone jack.
 - Dual GPIO vibrators (implemented as gpio-pwm because they are
   quite strong)
 - Multiple face buttons, dual analog joysticks, and dual analog
   triggers
 - PWM fan with tach pin.

The device also contains the following hardware that is partially or
currently not working:
 - 1920x1080 DSI display
 - HDMI port
 - USB-C port with DP alt-mode
 - TI bq25703 charger controller

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


New warnings running 'make CHECK_DTBS=y rockchip/rk3588s-gameforce-ace.dtb' for 20240726194948.109326-1-macroalpha82@gmail.com:

arch/arm64/boot/dts/rockchip/rk3588s-gameforce-ace.dtb: typec-portc@22: 'vbus-supply' is a required property

For the moment this is expected, because the regulator is driven by a
TI BQ25703 chip that I'm still working on getting supported. Is it
preferable to either keep it empty (and cause this error) or fill it
with a dummy regulator for now?

Thank you.
