* scripts/spelling.txt: add "intialization" pattern and fix typo instancesMasahiro Yamada2017-02-281-3/+3

* power: supply: add AC power supply driver for AXP20X and AXP22X PMICsQuentin Schulz2017-01-293-0/+266
| | | | | | | | | | | | | | | | | 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 availableQuentin Schulz2017-01-291-4/+66
| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | Reading both fault and status registers and logging any fault should take priority over handling status register update.

* power: supply: bq24190_charger: Don't read fault register outside ↵Liam Breck2017-01-201-67/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | irq_handle_thread() 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 <kernel@networkimprov.net> Acked-by: Mark Greer <mgreer@animalcreek.com> Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Sebastian Reichel <sre@kernel.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MAX14656 USB charger detector, also known as "AL32" is used to detect the presence and capabilities of attached USB chargers. The device is attached via I2C plus one interrupt line to signalize events. The device can be found in LG smartphones like LS665 and LS770, compatible devices are present in 4th/5th generation Amazon Kindle readers referenced in source code packages as "Maxim AL32". The initial version of this driver has been extracted from LG source code package LGLS665_Android_Lollipop_LS665ZV3, enriched with information from the Kindle_src_4.1.3 source code package and adapted to the current power class sysfs interface. Non-Standard Apple chargers which the device may detect are mapped to the USB Battery Charging Specification Revision 1.2 class USB_DCP.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GPIO charger is using a mix of the legacy GPIO interface and <linux/of_gpio.h> which is not the modern way to use GPIOs. Refactor like this: - Use a GPIO descriptor for the GPIO line used to monitor the charger. - Fetch the descriptor with devm_gpiod_get() as the first method. - If this fails and we are *not* using device tree, then start looking to see if we can use platform data instead. - After looking up and requesting a GPIO number with the legacy API, convert it to a descriptor. This way we can later isolate and drop the legacy code as more platforms move over to using descriptors.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to this commit the code was using 1 notifier_block for all types of charger cable, this is incorrect as the notifier_block becomes part of a linked-list and now the same notifier_block is part of 3 linked lists. This commit fixes this by using a separate nb per extcon cable. Note this happened to work fine sofar because axp288_charger was the only listener, so when added to each of the 3 notifier chains, the next pointer in the nb would be set to 0, so we've 3 heads pointing to the same nb, with its next pointing to NULL.

* | power: supply: axp288_charger: Fix wrong regmap_update_bitsHans de Goede2017-01-041-1/+1
| | | | | | | | | | | | | | | | To set a bit to 1 one needs to pass the mask for the bit to set as second argument into regmap_update_bits, not "1". Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Sebastian Reichel <sre@kernel.org>
* | power: supply: axp288_charger: Get and process initial hardware-stateHans de Goede2017-01-041-15/+17
| | | | | | | | | | | | | | | | | | | | | | | | Do not wait for an extcon notification before processing the cable states, instead queue the otg / cable work on probe to make sure we immediately process the initial hardware state. Note this also requiree moving the getting of the USB_HOST cable state from the extcon notifier to the workqueue function.

* | power: supply: axp288_charger: Some minor cleanupsHans de Goede2017-01-041-18/+5
| | | | | | | | | | | | | | | | | | | | | | | | Remove info->health, info->present and info->online caching, as no code is reading the cached values. Remove if (changed) check before calling power_supply_changed(), we return early from axp288_charger_extcon_evt_worker if nothing has changed, so the check is not needed.

* | power: supply: axp288_charger: Handle charger type changing without disconnectHans de Goede2017-01-041-18/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Deal with the charger type changing without a vbus-disconnect being reported in between the 2 charger type states: -Do not return from axp288_charger_extcon_evt_worker early in this case (track old_chg_type) -Make calling axp288_charger_enable_charger with the same value as before a nop, to avoid the need for the caller to check this -Do no do a dev_err when axp288_charger_enable_charger returns an error, axp288_charger_enable_charger already returns an error itself -Disable the charger before changing the charge-current setting (nop if vbus was seen as disconnected before the change) Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Sebastian Reichel <sre@kernel.org>
* | power: supply: axp288_charger: Actually get and use the USB_HOST extcon deviceHans de Goede2017-01-041-6/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nothing was setting info->otg.cable, so the extcon_get_cable_state_ calls on it would always return -EINVAL. This commit fixes this by actually setting info->otg.cable using the new extcon_get_extcon_dev_by_cable_id function. This commit also makes failing to register the extcon notifier for the USB_HOST cable an error rather then a warning, because we MUST have this notfier to properly disable the VBUS path when in host mode so that we're not drawing current from the 5V boost converter which is supplying power to the otg port when in host mode.

| | | | | | | | | | | | | | | | | | Move the charger_init_hw_regs() above the power_supply_register call, the axp288_charger_usb_set_property() uses axp288_chrg_info.max_cv and .max_cc which get set by charger_init_hw_regs().
