power_supply: wm97xx_battery: use power_supply_get_drvdata

2016-11-23T22:48:12+00:00

As the power supply framework provides a way to store and retrieve
private supply data, use it.

In the process, change the platform data for wm97xx_battery from a
container of a single struct wm97xx_batt_pdata to the direct point to wm97xx_batt_pdata.

wm8350_power: use permission-specific DEVICE_ATTR variants

2016-11-23T22:46:20+00:00

Use DEVICE_ATTR_RO for read only attributes.  This simplifies the source
code, improves readbility, and reduces the chance of inconsistencies.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// 
@ro@
declarer name DEVICE_ATTR;
identifier x,x_show;
@@

DEVICE_ATTR(x, \(0444\|S_IRUGO\), x_show, NULL);

@script:ocaml@
x << ro.x;
x_show << ro.x_show;
@@

if not (x^"_show" = x_show) then Coccilib.include_match false

@@
declarer name DEVICE_ATTR_RO;
identifier ro.x,ro.x_show;
@@

- DEVICE_ATTR(x, \(0444\|S_IRUGO\), x_show, NULL);
+ DEVICE_ATTR_RO(x);

power: ipaq_micro_battery: fix alias

The alias for the ipaq_micro_battery driver is incorrect, fix it so the
module can be auto-loaded.

power: supply: bq27xxx_battery: Fix register map for BQ27510 and BQ27520

2016-11-23T22:37:27+00:00

The BQ27510 and BQ27520 use a slightly different register map than the
BQ27500, add a new type enum and add these gauges to it.

bq24190_charger: Fix PM runtime use for bq24190_battery_set_property

2016-11-23T22:27:41+00:00

There's a typo, it should do pm_runtime_get_sync, not put.

power: supply: lp8788: remove an unneeded NULL check

2016-10-19T03:36:09+00:00

We checked that "pdata->chg_params" is non-NULL earlier in this function
so when we add "i" to it, it's still non-NULL.

power: supply: axp288_fuel_gauge: Fix module autoload

2016-10-19T03:15:07+00:00

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo drivers/power/supply/axp288_fuel_gauge.ko | grep alias
$

After this patch:

$ modinfo drivers/power/supply/axp288_fuel_gauge.ko | grep alias
alias:          platform:axp288_fuel_gauge

power: supply: max17040: Change register transaction length from 8 bits to 16 bits

2016-10-19T03:06:32+00:00

According to the datasheet, MAX17040 has six 16-bit registers.
Register reads and writes are only valid if all 16 bits are transferred.
Any write command that is terminated early is ignored.
So it's better to change register transacton length from 8 bits to 16 bits.

power: supply: bq27xxx_battery: don't update poll_interval param if same

2016-10-19T03:06:28+00:00

To avoid canceling the delayed workqueue needlessly, and scheduling an
immediate polling. Check if the new poll_interval value is different
than the previous setting.
