Yes, same here on another version of the kernel. I haven't had a look at the drivers themselves, but I suspect it's just that each driver registers in sysfs with its name: acpi names are "standard" like AC/BAT, and on phone devices, we have more roots name since we don't have ACPI. So you should probably not rely on the name of the directories, but instead on their content: for example, the 'capacity' file seems to exist only for battery, not for ac. > > I'll take a look to the doc, thanks. > > 2014-11-26 11:18 GMT+01:00 Alexandre Lissy <[email protected]>: >> Le 26/11/2014 11:15, Alexandre Lissy a écrit : >> >> [...] >>> and I think you may be interested by the SysFS Power supply class >>> regarding the bug you are referring to. >> >> Forgot to add the link: >> https://github.com/mozilla-b2g/codeaurora_kernel_msm/blob/t2m-flame-3.4-kk/Documentation/power/power_supply_class.txt >> >> _______________________________________________ >> dev-b2g mailing list >> [email protected] >> https://lists.mozilla.org/listinfo/dev-b2g > > > _______________________________________________ dev-b2g mailing list [email protected] https://lists.mozilla.org/listinfo/dev-b2g
