2016-09-21power: supply: sbs-battery: Cleanup removal of chip->pdataPhil Reid2-15/+11
There where still a few lingering references to pdata after commit power: supply: sbs-battery: simplify DT parsing. Remove pdata from struct·sbs_info and conditional checks to ser if this was set from the i2c read / write functions. Instead of call max in each function for incrementing poll_retry_count do it once in the probe function. Fixup null pointer dereference in to pdata in sbs_external_power_changed. Change retry counts to u32 to avoid need for max. Signed-off-by: Phil Reid <preid@electromag.com.au> Signed-off-by: Sebastian Reichel <sre@kernel.org>

2016-09-19sbs-battery: make writes to ManufacturerAccess optionalGuenter Roeck1-14/+15
According to the Smart Battery Data Specification, the use of ManufacturerAcess (register 0x0) is implementation-defined. 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.

2016-09-07power: supply: sbs-battery: simplify DT parsingArnd Bergmann1-67/+31
After the change to use the gpio descriptor interface, we get a warning if -Wmaybe-uninitialized is added back to the build flags (it is currently disabled: drivers/power/supply/sbs-battery.c: In function 'sbs_probe': drivers/power/supply/sbs-battery.c:760:28: error: 'pdata' may be used uninitialized in this function [-Werror=maybe-uninitialized] The problem is that if neither the DT properties nor a platform_data pointer are provided, the chip->pdata pointer gets set to an uninitialized value. 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.

2016-09-05power: supply: bq24735-charger: Request status GPIO with initial input setupPaul Kocialkowski2-31/+12
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. While at it, this switches the driver over to gpiod API. Signed-off-by: Paul Kocialkowski <contact@paulk.fr> Signed-off-by: Sebastian Reichel <sre@kernel.org>

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.
