mfd: axp20x: Correct AXP806 POK interrupt prefix

2018-05-16T08:21:48+00:00

When AXP806 support was added, POK was incorrectly expanded to PWROK. However, the datasheet lists them as POK[LSNP], which is the same as on the AXP288. Furthermore, the registers associated with POK functions are the same as the PEK on the other AXP PMICs. This suggests that "POK" means "Power On Key", much like "PEK" means "Power Enable Key", instead of "Power OK". This patch changes the "PWROK" prefix to "POK" for these interrupts.

Jonathan writes: First round of new devices, features and cleanups for IIO in the 4.17 cycle. Outside of IIO * Strongly typed 64bit int_sqrt function needed by the mlx90632 New device support * adc081s - New driver supporting adc081s, adc101s and adc121s TI ADCs. * ad5272 - New driver supproting the ad5272 and ad5274 ADI digital potentiometers with DT bindings. * axp20x_adc - support the AXP813 ADC - includes rework patches to prepare for this. * mlx90632 - New driver with dt bindings for this IR temperature sensor. Features * axp20x_adc - Add DT bindings and probing. * dht11 - The sensor has a wider range than advertised in the datasheet - support it. * st_lsm6dsx - Add hardware timestamp su9pport. Cleanups * ABI docs - Update email contact for Matt Ranostay * SPDX changes - Matt Ranostay has moved his drivers over to SPDX. Currently we are making this an author choice in IIO. * ad7192 - Disable burnout current on misconfiguration. No actually effect as they simply won't work otherwise. * ad7476 - Drop a license definition that was replicating information in SPDX tag. * ade7758 - Expand buf_lock to cover both buffer and state protection allowing unintented uses of mlock in the core to be removed. * ade7759 - Align parameters to opening parenthesis. * at91_adc - Depend on sysfs instead of selecting it - for try wide consistency. * ccs811 - trivial naming type for a define. * ep93xx - Drop a redundant return as a result checking platform_get_resource. * hts221 - Regmap conversion which simplifies the driver somewhat. - Clean up some restricted endian cast warnings. - Drop a trailing whitespace from a comment - Drop an unnecessary get_unaligned by changing to the right 16bit data type. * ms5611 - Fix coding style in the probe function (whitespace) * st_accel - Use strlcpy instead of strncpy to avoid potentially truncating a string.

iio: adc: axp20x_adc: add support for AXP813 ADC

2018-01-30T18:33:25+00:00

The X-Powers AXP813 PMIC is really close to what is already done for AXP20X/AXP22X. There are two pairs of bits to set the rate (one for Voltage and Current measurements and one for TS/GPIO0 voltage measurements) instead of one. The register to set the ADC rates is different from the one for AXP20X/AXP22X. GPIO0 can be used as an ADC (measuring Volts) unlike for AXP22X. The scales to apply to the different inputs are unlike the ones from AXP20X and AXP22X. Signed-off-by: Quentin Schulz Acked-by: Jonathan Cameron Signed-off-by: Jonathan Cameron

regulator: axp20x: Add support for AXP813 regulators

2017-10-04T10:49:04+00:00

The AXP813 PMIC has 7 DC-DC buck regulators, 16 LDOs (including the fixed RTC LDO and 2 GPIO LDOs), and 1 switchable. The drive-vbus feature is also supported. All the hardware details are very similar to the AXP803, with the following exceptions: - Extra DCDC7 buck regulator, with the same range as DCDC6 - SWitch now has a separate supply pin, instead of being chained internaly from DCDC1 - RTC LDO output voltage is now 1.8V - FLDO3 is an LDO with switchable supplies, but unconfigurable output voltage. The voltage is always half that of its supply. Support for FLDO3 is currently unimplemented, as it requires runtime switching of its supplies, something the regulator subsystem does not support. It is not used in either the reference designs nor actually produced boards available. Signed-off-by: Chen-Yu Tsai Tested-by: Maxime Ripard Acked-by: Maxime Ripard Signed-off-by: Mark Brown

mfd: axp20x: Add support for AXP813 PMIC

2017-09-05T07:46:00+00:00

The X-Powers AXP813 PMIC is normally used with Allwinner's A83T SoC. It has the same range of functions as other X-Powers PMICs, such as DC-DC buck converter and linear regulator outputs, AC-IN and VBUS power supplies, power button trigger, GPIOs, ADCs, and a battery charger. Note that the IRQ table given in the datasheet is incorrect: in IRQ enable/status registers 1, there are separate IRQs for ACIN and VBUS, instead of bits [7:5] being the same as bits [4:2]. So it shares the same IRQs as the AXP803, rather than the AXP288. This patch adds basic mfd support for it, with only the power button enabled.

AXP803 is a new PMIC chip produced by X-Powers, usually paired with A64 via RSB bus. The PMIC itself is like AXP288, but with RSB support and dedicated VBUS and ACIN. Add support for it in the axp20x mfd driver. Currently only power key function is supported. Signed-off-by: Icenowy Zheng Signed-off-by: Lee Jones

mfd: axp20x: Correct name of temperature data ADC registers

2017-04-27T08:25:04+00:00

The registers 0x56 and 0x57 of AXP22X PMIC store the value of the internal temperature of the PMIC. This patch modifies the name of these registers from AXP22X_PMIC_ADC_H/L to AXP22X_PMIC_TEMP_H/L so their purpose is clearer.
