Hi, This is PATCHv1 for converting twl4030-madc to the IIO API and adding DT support. The plan is to remove the private twl4030-madc API once all users have been removed or converted to the IIO API. The patchset compiles and has been tested on my Nokia N900. Changes since RFCv4 [0]: * Fixup all stuff found by Lee Jones and Jonathan Cameron in RFCv4. - Fixup kerneldoc comments - Move ARRAY_SIZE() into correct patch. I accidently rebased it into the wrong one. - Use sizeof(*madc) instead of sizeof(struct twl4030_madc_data) - Only call of_property_read_bool() if there is no pdata - I left the brackets in "reg_base + (2 * i)". They have been requested by Lee Jones and I think they make it easier to understand what is going on. * Add a bunch of Acked-By statements from those two * Add new patch, which adds *_mean_raw sysfs ABI documentation as requested by Jonathan Cameron * Add another patch, which provides iio_read_channel_average_raw(), so that drivers using the old API can be converted to the IIO API. * I switched from RFC to PATCH prefix. TODO: * Wait for feedback from DT binding maintainers * Wait for feedback from Marek Belisko, who is testing the change with twl4030-madc-battery driver on GTA04 [0] https://lkml.org/lkml/2014/2/26/482 -- Sebastian Sebastian Reichel (9): mfd: twl4030-madc: Use managed resources mfd: twl4030-madc: Add DT support and convert to IIO framework mfd: twl4030-madc: Cleanup driver mfd: twl-core: Add twl_i2c_read/write_u16 mfd: twl4030-madc: Use twl_i2c_read/write_u16 for 16 bit registers Documentation: DT: Document twl4030-madc binding mfd: twl4030-madc: Move driver to drivers/iio/adc iio: documentation: Add ABI documentation for *_mean_raw iio: inkern: add iio_read_channel_average_raw Documentation/ABI/testing/sysfs-bus-iio | 8 + .../devicetree/bindings/iio/adc/twl4030-madc.txt | 24 ++ drivers/iio/adc/Kconfig | 10 + drivers/iio/adc/Makefile | 1 + drivers/{mfd => iio/adc}/twl4030-madc.c | 301 +++++++++++++-------- drivers/iio/inkern.c | 18 ++ drivers/mfd/Kconfig | 10 - drivers/mfd/Makefile | 1 - include/linux/i2c/twl.h | 12 + include/linux/i2c/twl4030-madc.h | 2 +- include/linux/iio/consumer.h | 13 + 11 files changed, 276 insertions(+), 124 deletions(-) create mode 100644 Documentation/devicetree/bindings/iio/adc/twl4030-madc.txt rename drivers/{mfd => iio/adc}/twl4030-madc.c (75%) -- 1.9.0 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
