[PATCH 0/3] Add wiko-chuppito devictree

[Paul Adam via B4 Relay]

Add bindings vor Wiko SAS and wiko-chuppito
which are used in the devicetree.

Then introduce an initial device tree for Wiko PULP 4G.
Includes support for:
- UART
- USB (no OTG)
- Internal storage
- MicroSD
- Volume keys + Power button
- Touchscreen
- Backlight
- Accelerometer: Invensense MPU6880
- Magnetometer: Asahi Kasei AK09911
- Hall sensor: Rohm BU52021HFV
- Proximity sensor
- Vibrator
- Earpiece
- Microphone 1
- Headphones
- Wifi
- Bluetooth
- GPU

Domain is wikomobile, so use that one... unless wiko.com is the same -
looks kind of as, but then use correct address.

I think the GPIO prefix is unnecesary here and below

Looks like the driver has a number of CHIP_IDs - you can be sure which chip
specifically this is by printing it out

Do things break if you remove this line?

Is there a reason for this?

Please unbreak this line after '='

I tested it without and it still works. I just included it because
it was on the pmos msm8916 mainlining wiki page.

I removed the always-on property, it was for testing purposes.
mpss_mem is needed for audio to work.
I removed mdss since it is only needed for the panel.
Should the gpu only be enabled when the panel is added?


Also should I wait some time for additional comments or immediatly
send a new version when all remarks are addressed?

Normally one would wait some 2-3 days after sending. Because we're now in

new patches are accepted yet), some people will be grumpy and actively refuse
to review your changes but I wouldn't pay too much attention to that
