* ktime: Cleanup ktime_set() usageThomas Gleixner2016-12-251-1/+1
| | | | | | | | | | ktime_set(S,N) was required for the timespec storage type and is still useful for situations where a Seconds and Nanoseconds part of a time value needs to be converted. For anything where the Seconds argument is 0, this is pointless and can be replaced with a simple assignment.

| | | | | | | | | | | | | | | | | | | | | | | | 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.

It appears that some batteries use writes to this register in order to implement certain functionality, but others may simply NAK all writes to it. As a result, write failures to ManufacturerAccess should not be used as an indicator of battery presence, nor as a failure to enter sleep mode. The failed write access was seen with SANYO AP13J3K.

Looking at the code some more, I found that the sbs_of_populate_pdata function is more complex than necessary and has confusing calling conventions of possibly returning a valid pointer, a NULL pointer or an ERR_PTR pointer (in addition to the uninitialized pointer). To fix all of that, this gets rid of the chip->pdata pointer and simply moves the two integers into the sbs_info structure. This makes it much clearer from reading sbs_probe() what the precedence of the three possible values are (pdata, DT, hardcoded defaults) and completely avoids the #ifdef CONFIG_OF guards as of_property_read_u32() gets replaced with a compile-time stub when that is disabled, and returns an error if passed a NULL of_node pointer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This requests the status GPIO with initial input setup. It is required to read the GPIO status at probe time and thus correctly avoid sending I2C messages when AC is not plugged. When requesting the GPIO without initial input setup, it always reads 0 which causes probe to fail as it assumes the charger is connected, sends I2C messages and fails.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the charger status change interrupt support, it will report the power supply changed event. This interrupt is generated by one of the conditions as below: - the state machine jumps out of or into the EOC state - the CHGIN input voltage goes out of or into the valid range. - the battery temperature goes out of or into the valid range. - the PRECHARGE time-out occurs. - the total charge time-out occurs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the charger is missing (disconnected), it is safe to assume that the charger chip is no charging. This is especially relevant when a status GPIO is present and the charger is getting disconnected. bq24735_charger_is_charging will be triggered due to the interrupt then, it will attempt to read whether it is charging through i2c, which will fail as the charger is disconnected. This also fixes that specific issue. Signed-off-by: Paul Kocialkowski <contact@paulk.fr> Signed-off-by: Sebastian Reichel <sre@kernel.org>
