iio: twl6030-gpadc: TWL6030, TWL6032 GPADC driver

2013-08-17T14:50:57Z

The GPADC is general purpose ADC found on TWL6030, and TWL6032 PMIC, known also as Phoenix and PhoenixLite. The TWL6030 and TWL6032 have GPADC with 17 and 19 channels respectively. Some channels have current source and are used for measuring voltage drop on resistive load for detecting battery ID resistance, or measuring voltage drop on NTC resistors for external temperature measurements. Some channels measure voltage, (i.e. battery voltage), and have voltage dividers, thus, capable to scale voltage. Some channels are dedicated for measuring die temperature. Some channels are calibrated in 2 points, having offsets from ideal values kept in trim registers. This is used to correct measurements. The differences between GPADC in TWL6030 and TWL6032: - 10 bit vs 12 bit ADC; - 17 vs 19 channels; - channels have different purpose(i.e. battery voltage channel 8 vs channel 18); - trim values are interpreted differently. Based on the driver patched from Balaji TK, Graeme Gregory, Ambresh K, Girish S Ghongdemath.

iio: Add a comment to about alphabetical order to Kconfigs and Makefiles

2013-08-03T17:40:36Z

Keeping Makefile and Kconfig entries in alphabetical order usually works better than just appending new entries at the end, since it reduces the amount of conflicts. This patch adds a comment to the IIO Kconfig and Makefile files to document that the entries should be kept in alphabetical order. Also reorder those entries which weren't in alphabetical order yet.

Merge tag 'mfd-3.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6

2012-12-17T02:55:20Z

Pull MFS update from Samuel Ortiz: "This is the MFD patch set for the 3.8 merge window. We have several new drivers, most of the time coming with their sub devices drivers: - Austria Microsystem's AS3711 - Nano River's viperboard - TI's TPS80031, AM335x TS/ADC, - Realtek's MMC/memstick card reader - Nokia's retu We also got some notable cleanups and improvements: - tps6586x got converted to IRQ domains. - tps65910 and tps65090 moved to the regmap IRQ API. - STMPE is now Device Tree aware. - A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ APIs and a conversion to the recently added PWM framework. - sta2x11 gained regmap support. Then the rest is mostly tiny cleanups and fixes, among which we have Mark's wm5xxx and wm8xxx patchset." Far amount of annoying but largely trivial conflicts. Many due to __devinit/exit removal, others due to one or two of the new drivers also having come in through another tree. * tag 'mfd-3.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: (119 commits) mfd: tps6507x: Convert to devm_kzalloc mfd: stmpe: Update DT support for stmpe driver mfd: wm5102: Add readback of DSP status 3 register mfd: arizona: Log if we fail to create the primary IRQ domain mfd: tps80031: MFD_TPS80031 needs to select REGMAP_IRQ mfd: tps80031: Add terminating entry for tps80031_id_table mfd: sta2x11: Fix potential NULL pointer dereference in __sta2x11_mfd_mask() mfd: wm5102: Add tuning for revision B mfd: arizona: Defer patch initialistation until after first device boot mfd: tps65910: Fix wrong ack_base register mfd: tps65910: Remove unused data mfd: stmpe: Get rid of irq_invert_polarity mfd: ab8500-core: Fix invalid free of devm_ allocated data mfd: wm5102: Mark DSP memory regions as volatile mfd: wm5102: Correct default for LDO1_CONTROL_2 mfd: arizona: Register haptics devices mfd: wm8994: Make current device behaviour the default mfd: tps65090: MFD_TPS65090 needs to select REGMAP_IRQ mfd: Fix stmpe.c build when OF is not enabled mfd: jz4740-adc: Use devm_kzalloc ...
