If we detect a Samsung SDI battery, we return a static struct power_supply_battery_info and avoid looking further. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> --- ChangeLog v3->v4: - Rebase on Sebastians linux-power-supply tree. - One more oneline bug in the Janice charging parameter block. - Add static keyword to tables ChangeLog v2->v3: - Fix a whole bunch of tables after realizing that completely different battery data was used if CONFIG_SAMSUNG_BATTERY was set for Golden, Kyle, Codina and Skomer. ChangeLog v1->v2: - Bump tolerance to 40% on all BTI resistances - Change config option to bool, as we are calling OUT from the supply core this cannot be compiled into a module - Augment data to support low/high temperature charge current and voltages. Sadly the vendor tree just provide one and the same current and voltage for all of these. --- drivers/power/supply/Kconfig | 6 + drivers/power/supply/Makefile | 1 + drivers/power/supply/power_supply_core.c | 8 + drivers/power/supply/samsung-sdi-battery.c | 919 +++++++++++++++++++++ drivers/power/supply/samsung-sdi-battery.h | 13 + 5 files changed, 947 insertions(+) create mode 100644 drivers/power/supply/samsung-sdi-battery.c create mode 100644 drivers/power/supply/samsung-sdi-battery.h
