Hi,
I am trying to get this working on our bq27421.
But the only message I get is:
[ 6.086407] bq27xxx-battery 1-0055: data memory update not supported for chip
A little research shows that this message comes from
http://elixir.free-electrons.com/linux/v4.13-rc7/source/drivers/power/supply/bq27xxx_battery.c#L1279
So di->dm_regs is NULL.
But doing an fgrep for dm_regs shows no line of code where the pointer is set
to a non-null value:
master hns$ fgrep -R dm_regs *
drivers/power/supply/bq27xxx_battery.c: .class = (di)->dm_regs[i].subclass_id, \
drivers/power/supply/bq27xxx_battery.c: .block = (di)->dm_regs[i].offset /
BQ27XXX_DM_SZ, \
drivers/power/supply/bq27xxx_battery.c: struct bq27xxx_dm_reg *reg =
&di->dm_regs[reg_id];
drivers/power/supply/bq27xxx_battery.c: if (!di->dm_regs) {
drivers/power/supply/bq27xxx_battery.c: max =
di->dm_regs[BQ27XXX_DM_DESIGN_ENERGY].max;
drivers/power/supply/bq27xxx_battery.c: max =
di->dm_regs[BQ27XXX_DM_DESIGN_CAPACITY].max;
drivers/power/supply/bq27xxx_battery.c: min =
di->dm_regs[BQ27XXX_DM_TERMINATE_VOLTAGE].min;
drivers/power/supply/bq27xxx_battery.c: max =
di->dm_regs[BQ27XXX_DM_TERMINATE_VOLTAGE].max;
Binary file drivers/power/supply/bq27xxx_battery.ko matches
Binary file drivers/power/supply/bq27xxx_battery.o matches
Binary file drivers/power/supply/bq27xxx_battery_i2c.ko matches
Binary file drivers/power/supply/bq27xxx_battery_i2c.o matches
include/linux/power/bq27xxx_battery.h: struct bq27xxx_dm_reg *dm_regs;
master hns$
What am I doing wrong here?
BR and thanks,
Nikolaus
