[PATCH v5 0/3] iio: vcnl3020: add periodic mode, threshold options

[Ivan Mikhaylov]

Add periodic mode enablement, high/low threshold options.

Changes from v1:
 1. Remove changes for hwmon driver and changes affecting
vcnl3020 data structure.
 2. Add enable/disable periodic mode functions.

Changes from v2:
 1. Minor fixes from Jonathan's comments.

Changes from v3:
 1. add DMA safe buffer in vcnl3020_data and use it on bulk_read/write
    calls
 2. put vcnl3020_is_in_periodic_mode in vcnl3020_measure_proximity and
    vcnl3020_write_proxy_samp_freq
 3. add mutex instead of iio_claim in vcnl3020_write_proxy_samp_freq
 4. out_mutex -> err_unlock

Changes from v4:
 1. split into 3 patches - DMA safe buffer, periodic mode, change
    iio_claim/release on mutex.
 2. add dev_err for regmap_read/write
