[PATCH v3 00/41] iio: simplify with regmap_set_bits(), regmap_clear_bits()

[PATCH v3 00/41] iio: simplify with regmap_set_bits(), regmap_clear_bits()

[Trevor Gamblin]

Simplify the way regmap is accessed in iio drivers.

Instead of using regmap_update_bits() and passing the mask twice, use
regmap_set_bits().

Instead of using regmap_update_bits() and passing val = 0, use
regmap_clear_bits().

The series is marked as v3, but the previous two revisions were single
patches. There was also a resend of v1 due to not properly CCing the
mailing lists on the first attempt. Trailers were pulled in from those
where relevant.

[PATCH v3 09/41] iio: adc: cpcap-adc: make use of regmap_clear_bits(), regmap_set_bits()

[Trevor Gamblin]

Instead of using regmap_update_bits() and passing the mask twice, use
regmap_set_bits().

Instead of using regmap_update_bits() and passing val = 0, use
regmap_clear_bits().

[PATCH v3 14/41] iio: adc: mp2629_adc: make use of regmap_clear_bits(), regmap_set_bits()

[Trevor Gamblin]

Instead of using regmap_update_bits() and passing the mask twice, use
regmap_set_bits().

Instead of using regmap_update_bits() and passing val = 0, use
regmap_clear_bits().

[PATCH v3 28/41] iio: light: adux1020: make use of regmap_clear_bits(), regmap_set_bits()

[Trevor Gamblin]

Instead of using regmap_update_bits() and passing the mask twice, use
regmap_set_bits().

Instead of using regmap_update_bits() and passing val = 0, use
regmap_clear_bits().

Instead of using regmap_update_bits() and passing the mask twice, use
regmap_set_bits().

Instead of using regmap_update_bits() and passing val = 0, use
regmap_clear_bits().

Now fits neatly on one line at precisely 80 chars.
I rewrapped whilst applying.

Applied to the togreg branch of iio.git and pushed out as testing for 0-day
