RFE: Add support for Jolla Tablet

[pcfe]

Hello,

it would be nice if the Jolla Tablet was supported.

On the Jolla Tablet I have the following in /sys/ when not plugged in,

[root@jolla-tablet ~]# ls -1 /sys/class/power_supply/
dollar_cove_battery
dollar_cove_charger
[root@jolla-tablet ~]# ls -1 /sys/class/power_supply/dollar_cove_battery/

charge_full
charge_full_design
charge_now

[root@jolla-tablet ~]# ls -1 /sys/class/power_supply/dollar_cove_charger/

[nemo@jolla-tablet dollar_cove_battery]$ cat temp

[nemo@jolla-tablet dollar_cove_battery]$ cat health 
Good
[nemo@jolla-tablet dollar_cove_battery]$ cd /sys/class/power_supply/dollar_cove_charger/
[nemo@jolla-tablet dollar_cove_charger]$ cat charge_control_limit
0
[nemo@jolla-tablet dollar_cove_charger]$ cat charge_control_limit_max 
4
[nemo@jolla-tablet dollar_cove_charger]$ cat enable_charging 
0
[nemo@jolla-tablet dollar_cove_charger]$ cat enable_charger 
0

and this when plugged in

[nemo@jolla-tablet dollar_cove_charger]$ cat charge_control_limit_max 
4
[nemo@jolla-tablet dollar_cove_charger]$ cat charge_control_limit
0
[nemo@jolla-tablet dollar_cove_charger]$ cat enable_charger 
1
[nemo@jolla-tablet dollar_cove_charger]$ cat enable_charging 
1
[nemo@jolla-tablet dollar_cove_charger]$ cat charge_current 
1800
[nemo@jolla-tablet dollar_cove_charger]$ cat charge_term_cur 
250
[nemo@jolla-tablet dollar_cove_charger]$ cat charge_voltage 
4350
[nemo@jolla-tablet dollar_cove_charger]$ cat /sys/class/power_supply/dollar_cove_battery/status 
Charging

Is there anything else needed to add support for this (granted pretty old) hardware?

Hi,

Sorry for the long delay, I kinda really forgot about this one until today...

Thanks for the comprehensive list of files and their contents! I think I managed to find all the necessary files. As I don't have the device on-hand, it's hard to tell if something doesn't work. Could you test it and report back to me? You can download 4.1.0-beta1 here from GitHub.

[direc85]

I forgot to add the Jolla Tablet charger control file to the root service, so charger control won't work in beta1. Please download 4.1.0-beta2 instead :sweat_smile:

[direc85]

4.1.0 is now released with the support, so I'm closing this. Post a new message here if it doesn't work after all.

just to wrap this up, thanks for the code changes and not to worry about the delay. But sadly my Jolla Tablet died in the mean time (device was old and I seem to have done too many rounds of flashing for the old flash memory to survive). So I can no longer test :-(

[direc85]

I'm sorry to hear that :(

Hi @direc85! I've downloaded Battery Buddy 3.17.0-1 source code and added commit 354ffcb295ec330ce4112fc4f8b34a168772cb63. I've installed in my tablet with sfos 4.2, and it works perfect :)

[direc85]

Thank you for testing! Closing as fixed :partying_face:
