This patch set adds initial support for the Dialog DA9150 Integrated Charger &
Fuel-Gauge IC. The device also provides GPIO and GPADC functionality.
In this patch set the following is provided:
- MFD Core support and DT bindings documentation.
- IIO GPADC support and DT bindings documentation.
- Power Supply Charger support and DT bindings documentation.
- Update to MAINTAINERS file to add DA9150 files to Dialog support list.
- Update to IIO ABI document to add info regarding input current readings.
To keep patch submission from being too large, support for GPIO and Fuel-Gauge
will come after initial support patches are accepted.
This patch set is baselined against the v3.18-rc6 kernel version.
Changes in v4:
- Correct MODULE_AUTHOR lines so e-mail addresses correctly surrounded with <>.
- Update to MFD binding document to remove unnecesary I2C reference, make
module description generic, and add link to interrupt binding documentation.
- For GPADC driver, irq request moved above iio related calls in probe() to
mirror correctly the remove() function ordering, as requested.
- For charger driver, remove additional sysfs entries as these are not necessary
(debug only).
- For charger driver, add helper function for requesting IRQs, to make probe()
function cleaner/simpler.
Changes in v3:
- IRQ register and remove helper functions removed from MFD, deemed unnecessary.
Drivers using helper functions updated to use direct calls to relevant
kernel framework functions.
- MFD I2C file removed and code folded into -core file as requested.
- MFD core now buildable as driver module.
- Platform data structure definition moved into core header, pdata.h removed.
- Update functions in GPADC driver to be static, where appropriate.
- Change units of GPADC readings to match ABI documentation. Updates to charger
driver also made to align with this modification.
- Refactor GPADC temp calculations to use scale & offset method.
- Scale values now returned as FRACTIONAL to allow for accurate conversion in
user-space.
- Tidy up of GPADC scale, offset and raw functions to return from case statements
with correct return types.
- Update GPADC channel macros naming to prefix with DA9150, prevent conflict.
- GPADC GPIO voltage readings actually in 6V range, updated accordingly.
- Addition to IIO ABI document to add details on input current readings.
- Small style updates to address comments.
Changes in v2:
- Drop devicetree prefix patch as this is being dealt with separately.
- IIO framework fix patch removed from set, has already been accepted/merged.
- Use __ instead of _ for protecting #ifdefs in headers.
- Moved private data & definitions to source files and remove unwanted headers.
- Bug fix to EXPORT_SYMBOL for common functions in MFD core used by
sub-devices, so they can be correctly built as kernel modules.
- Removed unnecessary channels from GPADC IIO driver to simplify code.
- For GPADC IIO driver, VBAT reading now provides scale and offset values as it
is a linear scale.
- GPADC read code refactored to make it tidier.
- Remove use of flag to indicate GPADC availability. IIO framework should
indicate need to defer if it's not yet instantiated.
- Unwanted comments removed.
- Removed conditional shutdown of device (Charger/MFD) as this is not needed.
- Removed AC type supply from charger as device cannot differentiate. Now just
uses USB supply type.
- Removed use of invalid-tbat flag from platform data as it doesn't really add
anything to the driver except forcing battery present status.
- Bug fix for checking of usb_phy validity in Charger probe() function.
- Addition of common IRQ release function to allow sub-devices to explicitly
tidy up IRQs when devm clean up is too late.
- Improved tidy up of resources in charger.
- Fix location of IIO GPADC related devicetree binding document so it now
resides correctly under 'adc' directory.
- Add update to MAINTAINERS file to include these files in Dialog support list.

+Device Description
+------ -----------
+da9150-gpadc : General Purpose ADC
+da9150-charger : Battery Charger
+
+======
+
+Required properties:
+- compatible : Should be "dlg,da9150"
+- reg: Specifies the I2C slave address
+- interrupt-parent: Specifies the phandle of the interrupt controller to which
+ the IRQs from da9150 are delivered to.
+- interrupts: IRQ line info for da9150 chip.
+- interrupt-controller: da9150 has internal IRQs (own IRQ domain).
+ (See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
+ further information relating to interrupt properties)
+
+Sub-devices:
+- da9150-gpadc: See Documentation/devicetree/bindings/iio/adc/da9150-gpadc.txt
+- da9150-charger: See Documentation/devicetree/bindings/power/da9150-charger.txt
+
+
+Example:
+
+ charger_fg: da9150@58 {
+ compatible = "dlg,da9150";
+ reg = <0x58>;
+ interrupt-parent = <&gpio6>;
+ interrupts = <11 IRQ_TYPE_LEVEL_LOW>;
+ interrupt-controller;
+
+ gpadc: da9150-gpadc {

Moving iio_map_array_register around requires an adaption of the error out path.

BTW: If you use sizeof(*gpadc) instead (like it is usually done as well),

I preferred to be explicit that the item is a struct, but really not that fussed
either way. Also have been asked previously in a separate driver to make the
same mod you mention so will update accordingly.
