Bug#927163: linux-image-4.19.0-4-amd64: Missing modules for AXP288 power fuel gauge driver

[Bernhard Übelacker <bernhardu@mailbox.org>]

Hello Marcus Lundblad,
I don't know if it is related - I own a Baytrail
device that contains also these axp devices.
Back in late 2017 I got some help from Hans de Goede,
who worked that time in that area.
There my battery information was also missing with
the stock debian kernel.

He suggested to build a kernel with the config from a
"v4.14-footrail" branch from following repo first.
     https://github.com/jwrdegoede/linux-sunxi/

I could reduce the differences to following:

#        Note on x86 this provides an ACPI OpRegion, so this must be 'y'
#        (builtin) and not a module, as the OpRegion must be available as
#        soon as possible. For the same reason the I2C bus driver options
#        I2C_DESIGNWARE_PLATFORM and I2C_DESIGNWARE_BAYTRAIL must be 'y' too.
#    I2C_DESIGNWARE_PLATFORM=y
#    I2C_DESIGNWARE_BAYTRAIL=y
#    MFD_AXP20X_I2C=y

Could this be relevant for Cherrytrail too?

Kind regards,
Bernhard
