Subject: [PATCH v3 0/3] iio: accel: add support for Memsic MXC4005

This patch set adds support for Memsic MXC4005XC 3-axis accelerometer
sensor. The first patch adds basic support for the accelerometer, with
raw readings, the second patch adds support for buffer mode and the last
one adds the data ready trigger.

---
Changes since v1:
- fixes for the comments (coding style, proper buffer length,
  available_scan_masks)
- remove unnecessary locking for regmap operations since regmap has an
  internal locking mechanism
- keep the mutex for set_trigger_state operation to protect the state
  variable trigger_enabled

Changes since v2:
 - use the MXC4005_REGMAP_NAME for regmap_config instead of REGMAP_DRV_NAME
 - replace struct i2c_client *client with struct device *dev
 - remove redundant REGCACHE_NONE option from regmap_config
 - other small style fixes
 - fix buffer size
 - remove read interrupt source register
 - remove the thread handler since we only have one interrupt
 - make irq->client > 0 since IRQ 0 is not valid
 - rework the irq handler by adding try_to_reenable callback
 - use iio_pollfunc_store_time for timestamps
