Letux Kernel

Issue 937: Kobo Clara/Tolino Shine missing features

Reported by Nikolaus Schaller, Nov 19, 2019

a) Display
b) Charger
c) Power management (?)
d) WiFi

Otherwise the code with patches submitted for v5.5-rc1 is working 
well:
* boot
* MMC
* RTC
* USB-client / ethernet gadget
* touch screen
* LED
* lid hall sensor and power button event driver

Display is a tough thing - how to add an eInk driver to the kernel.

WiFi has solutions (out of tree): 
https://github.com/jwrdegoede/rtl8189ES_linux.git branch rtl8189fs

****************
The wifi module seems not to power down the card completely. You 
will see that the wifi-regulator is still on, but 'rmmod 8189fs' 
helps

Another missing feature is a fuel gauge. As far as I did see the 
PMIC chip has some ADCs integrated.

I guess it has even a full-featured fuel gauge (12bit, 1s sampling). 
But I have the impression, that the kobokernel additionally does its 
own thing. I have seen current consumption tables.
