[PATCH 0/3] Add initial support for BQ Aquaris X5

[Jonathan Albrieux]

Aquaris X5 (Longcheer L8910) is a smartphone released by BQ in 2015.

As part of msm8916-mainline project, this series aims to bring initial
mainline support for it.

Features added:
 - SDHCI (internal and external storage)
 - USB Device Mode
 - UART
 - Regulators
 - WiFi/BT
 - Volume buttons
 - Vibrator
 - Touchkeys backlight
 - Accelerometer and gyroscope sensor
 - Magnetometer sensor

[PATCH 1/3] arm64: dts: qcom: Add device tree for BQ Aquaris X5 (Longcheer L8910)

[Jonathan Albrieux]

BQ Aquaris X5 (Longcheer L8910) is a smartphone using the MSM8916 SoC.

Add device tree with initial support for:

 - SDHCI (internal and external storage)
 - USB Device Mode
 - UART
 - Regulators
 - WiFi/BT
 - Volume buttons
 - Vibrator
 - Touchkeys backlight

This device tree is based on downstream device tree from BQ and from
Longcheer L8915 device tree.

[PATCH 2/3] arm64: dts: qcom: msm8916: Add blsp_i2c3

[Jonathan Albrieux]

MSM8916 has another I2C QUP controller that can be enabled on
GPIO 10 and 11.

Add blsp_i2c3 to msm8916.dtsi and disable it by default.

Please sort I2C devices by their address.

Please add this after gpio110 to keep it sorted gpio-number-wise.

Things to consider for the future:


* DMA on I2C

* Merging in the -pins.dtsi to 8916.dtsi?

Re: [PATCH 1/3] arm64: dts: qcom: Add device tree for BQ Aquaris X5 (Longcheer L8910)

[Konrad Dybcio]

The sorting on smd_rpm_regulators & msmgpio seems off.. unless it's the new thing to put it at the end?

Also, did you forget the copyright header or is that on purpose?


Otherwise, LGTM

It's consistent like this for all MSM8916 device trees at least.

Back when I converted them I thought that it's kind of annoying to have
this large list of regulators and pinctrl placed right inbetween all
other device definitions. And it's even worse for apq8016-sbc.dtsi which
has this large list of gpio-line-names. It just makes it harder to see
the actual interesting definitions (new devices etc) in my opinion.

I think I mentioned this in my patch description back then
and Bjorn did not complain. :-)

But I understand this may be somewhat inconsistent with other qcom
device trees at the moment, so I suppose I would be fine with a patch
to order them entirely alphabetically.
(As long as it's consistent for all MSM8916 device trees...)

Thanks,
Stephan

This is ordered alphabetically. I haven't seen gpio-number order

Let me know if this order has to be changed, meanwhile I'll prepare
a v2 for the i2c device order and will prepare a v3 in case this
order too has to be changed.

Good to see another phone being supported. Can I ask you to cc:
phone-devel@vger.kernel.org with phone stuff?

How close are you to having useful phone calls?

You can do phone calls (with audio) and you can use mobile data, if you
have the patches for that. :) I'm trying to find time to finish up the
drivers needed for that, but I've been a bit short on time lately.

Actually we have come pretty far with MSM8916-based smartphones.
Most functionality is (somewhat) working at this point, the primary
open task is optimizing suspend/power consumption. Battery/charging
and camera is also tricky but works somewhat on some of the devices.

Most of the functionality is packaged in postmarketOS [1] and you can
find a list of the devices in the postmarketOS wiki [2]. Especially
the ones in the "community" category are quite similar in terms of
working functionality.

Yes, power consumption is a lot of fun :-(.

I know about postmarketOS (I even contributed a bit some time ago),
and watch it from time to time. Currently I'm using old Nokia 6151 for
phone calls, but would not mind switching. Work is ongoing in Droid 4
land -- phone calls are also "almost there". But the almost seems to
be a lot of work :-(.

It's fairly simple on Qualcomm SoCs once audio DSP and modem are working
(which is not that simple). I basically just tell the audio DSP to
stream voice call audio to the audio ports and then it does that without
involving the kernel.

It seems to work quite well, so far no one complained about quality or
something like that. Not sure if anyone is actively using it already
though :)

The work left is mainly making the driver more generic so it can work on
other Qualcomm SoCs as well (right now I have some things hardcoded).
Also, I still haven't fully figured out what is the best way to
integrate it into ASoC/UCM/..., so that it can be easily activated when
starting a voice call.

Ok, thanks for info :-).

On droid 4, we use mixer settings to configure audio system for a
call. Maemo Leste has some kind of component to automatically adjust
mixers when call is started. We use ofonod.
