power: supply: lp8788: prevent out of bounds array access

2017-05-14T12:06:00+00:00

commit bdd9968d35f7fcdb76089347d1529bf079534214 upstream. val might become 7 in which case stime[7] (array of length 7) would be accessed during the scnprintf call later and that will cause issues. Obviously, string concatenation is not intended here so just a comma needs to be added to fix the issue.

scripts/spelling.txt: add "intialization" pattern and fix typo instances

2017-02-28T02:43:47+00:00

Fix typos and add the following to the scripts/spelling.txt: intialization||initialization The "inintialization" in drivers/acpi/spcr.c is a different pattern but I fixed it as well in this commit.

power: supply: add AC power supply driver for AXP20X and AXP22X PMICs

2017-01-29T22:15:18+00:00

The X-Powers AXP20X and AXP22X PMICs expose the status of AC power supply. Moreover, the AXP20X can also expose the current current and voltage values of the AC power supply. This adds the driver which exposes the status of the AC power supply of the AXP20X and AXP22X PMICs.

power: supply: axp20x_usb_power: use IIO channels when available

2017-01-29T22:15:17+00:00

The X-Powers AXP20X PMIC exposes the current current and voltage measures via an internal ADC. This adds the possibility to read IIO channels directly for processed values rather than reading the registers and computing the value. For backward compatibility purpose, if the IIO driver is not compiled, this driver will fall back on previous behaviour which is direct register readings.

power: supply: max14656: Export I2C and OF device ID as module aliases

2017-01-29T22:15:17+00:00

If the driver is built as a module, I2C module alias information is not filled so the module won't be autoloaded. Export the I2C and OF devices ID to the module by using the MODULE_DEVICE_TABLE() macro.

power: supply: bq2415x: check for NULL acpi_id to avoid null pointer dereference

2017-01-21T02:35:07+00:00

acpi_match_device can potentially return NULL, so it is prudent to check if acpi_id is null before it is dereferenced. Add a check and an error message to indicate the failure. Signed-off-by: Colin Ian King Reviewed-by: Pali Rohár Signed-off-by: Sebastian Reichel

power: supply: bq24190_charger: Handle fault before status on interrupt

2017-01-20T11:43:11+00:00

Reading both fault and status registers and logging any fault should take priority over handling status register update. Fix by moving the status handling to later in interrupt routine.

power: supply: bq24190_charger: Don't read fault register outside irq_handle_thread()

2017-01-20T11:43:07+00:00

Caching the fault register after a single I2C read may not keep an accurate value. Fix by doing two reads in irq_handle_thread() and using the cached value elsewhere. If a safety timer fault later clears itself, we apparently don't get an interrupt (INT), however other interrupts would refresh the register cache. From the data sheet: "When a fault occurs, the charger device sends out INT and keeps the fault state in REG09 until the host reads the fault register. Before the host reads REG09 and all the faults are cleared, the charger device would not send any INT upon new faults. In order to read the current fault status, the host has to read REG09 two times consecutively. The 1st reads fault register status from the last read [1] and the 2nd reads the current fault register status." [1] presumably a typo; should be "last fault" Fixes: d7bf353fd0aa3 ("bq24190_charger: Add support for TI BQ24190 Battery Charger") Signed-off-by: Liam Breck Acked-by: Mark Greer Acked-by: Tony Lindgren Signed-off-by: Sebastian Reichel

power: supply: bq24190_charger: Call power_supply_changed() for relevant component

2017-01-20T11:43:03+00:00

We wrongly get uevents for bq24190-charger and bq24190-battery on every register change. Fix by checking the association with charger and battery before emitting uevent(s).
