The QG driver adds support for battery gauging and reporting the battery specific parameters to userspace. The driver comprises of the below files: qpnp-qg.c: Core QG driver qg-soc.c: SOC (state of charge) scaling operations qg-util.c: Common functions qg-battery-profile.c: Parsing battery profile from DT qg-profile-lib.c: Operations on battery profiles qg-sdam.c: SDAM interface for QG This commit also adds the below UAPI files, qg.h: QG data shared between kernel and userspace QG modules qg-profile.c: Profile data exchange between kernel and userspace.
