[PATCH] power: supply: qcom_battmgr: Report capacity on X1E80100

From: Liviu Nicoara

Date: Sun Sep 20 2026 - 15:34:19 EST


Commit 3f87baacea4d ("power: supply: qcom_battmgr: Report battery
capacity") added POWER_SUPPLY_PROP_CAPACITY to the SC8280XP battery
properties, computed from the firmware's charge and last-full values.
When commit cc3e883a0625 ("power: supply: qcom_battmgr: Add charge
control support") later gave X1E80100 a property table of its own, the
table was copied without the capacity property, so X1E80100 machines
expose energy_now and energy_full but no capacity.

The percentage is already computed for this variant in the shared
SC8280XP callback; only the property list is missing it. Add it, in the
same place it sits in the SC8280XP table.

Tested on a Dell XPS 13 9345: capacity reads 94 with energy_now
52640000 and energy_full 55540000.
