Subject: [PATCH v3 0/4] iio: bmc150 regmap and SPI

Hi,

this series converts the bmc150 driver to use regmap and adds an SPI interface.

Thanks for testing and review so far. I rebased the series onto v4.3-rc2 now
(the togreg branch seems to be on v4.2).
It still works for me but there were some differences regarding the chip id.

Changes in v3:
- Fixed type of variable 'step' which lead to compile warnings. Type is now
  size_t.
- Fixed patch that moved irq variable without reason
- Readded MODULE_* to the core driver
- Reintroduced check id NULL check

Changes in v2:
- Removed default values for regmap_config fields.
- Redesigned the fifo_transfer function to avoid running in errors first.
- Dropped irq checks patch as it is already mainline
- Core can now be built as module with autoselection of i2c and spi parts

As my hardware is missing an interrupt line from the SPI connected bmc150 I am
not able to test the iio buffer code path and the i2c code path. Tests would be
appreciated.

@Srinivas:
As there were some rebase conflicts on the first patch, I removed your
reviewed-by tag again for the moment.

Best regards,

Markus
