Signed-off-by: Quentin Schulz Acked-by: Maxime Ripard --- v3: - moved from switch to if condition in axp20x_adc_raw and axp22x_adc_raw, - removed DT support as DT node has been dropped, - use of platform_device_id - correctly defined the name of the iio device (name used to probe the driver), - added goto for errors in probe, - added iio_map_array_unregister to the remove function, v2: - removed unused defines, - changed BIT(x) to 1 << x when describing bits purpose for which 2 << x or 3 << x exists, to be consistent, - changed ADC rate defines to macro formulas, - reordered IIO channels, now different measures (current/voltage) of the same part of the PMIC (e.g. battery), have the same IIO channel in their respective IIO type. When a part of the PMIC have only one measure, a number is jumped, - left IIO channel mapping in DT to use iio_map structure, - removed indexing of ADC internal temperature, - removed unused iio_dev structure in axp20x_adc_iio, - added a structure for data specific to AXP20X or AXP22X PMICs instead of using an ID and an if condition when needing to separate the behaviour of both, - added a comment on batt_chrg_i really being on 12bits rather than what the Chinese datasheets say (13 bits), - corrected the offset for AXP22X PMIC temperature, - set the ADC rate to a value (100Hz) shared by the AXP20X and AXP22X, - created macro formulas to compute the ADC rate for each, - added a condition on presence of ADC_EN2 reg before setting/resetting it, - switched from devm_iio_device_unregister to the non-devm function because of the need for a remove function, - removed some dead code, drivers/iio/adc/Kconfig | 10 + drivers/iio/adc/Makefile | 1 + drivers/iio/adc/axp20x_adc.c | 606 +++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 617 insertions(+) create mode 100644 drivers/iio/adc/axp20x_adc.c -- 2.9.3 diff --git a/drivers/iio/adc/Kconfig b/drivers/iio/adc/Kconfig index 9c8b558..ed17fe1 100644 --- a/drivers/iio/adc/Kconfig +++ b/drivers/iio/adc/Kconfig @@ -154,6 +154,16 @@ config AT91_SAMA5D2_ADC To compile this driver as a module, choose M here: the module will be called at91-sama5d2_adc. +config AXP20X_ADC + tristate "X-Powers AXP20X and AXP22X ADC driver" + depends on MFD_AXP20X + help + Say yes here to have support for X-Powers power management IC (PMIC) + AXP20X and AXP22X ADC devices. + + To compile this driver as a module, choose M here: the module will be + called axp20x_adc. + config AXP288_ADC tristate "X-Powers AXP288 ADC driver" depends on MFD_AXP20X diff --git a/drivers/iio/adc/Makefile b/drivers/iio/adc/Makefile index d36c4be..f5c28a5 100644 --- a/drivers/iio/adc/Makefile +++ b/drivers/iio/adc/Makefile @@ -16,6 +16,7 @@ obj-$(CONFIG_AD7887) += ad7887.o obj-$(CONFIG_AD799X) += ad799x.o obj-$(CONFIG_AT91_ADC) += at91_adc.o obj-$(CONFIG_AT91_SAMA5D2_ADC) += at91-sama5d2_adc.o +obj-$(CONFIG_AXP20X_ADC) += axp20x_adc.o obj-$(CONFIG_AXP288_ADC) += axp288_adc.o obj-$(CONFIG_BCM_IPROC_ADC) += bcm_iproc_adc.o obj-$(CONFIG_BERLIN2_ADC) += berlin2-adc.o diff --git a/drivers/iio/adc/axp20x_adc.c b/drivers/iio/adc/axp20x_adc.c new file mode 100644 index 0000000..5ef6af8 --- /dev/null +++ b/drivers/iio/adc/axp20x_adc.c @@ -0,0 +1,606 @@ +/* ADC driver for AXP20X and AXP22X PMICs + * + * Copyright (c) 2016 Free Electrons NextThing Co. + * Quentin Schulz + * + * This program is free software;
