583e80a9ce drivers/1wire/ds28e17.c: Optimize I2C write followed by read to same address. 2018-12-11 07:09:03 -06:00

3cf830bd67 Merged in juniskane/nuttx_stm32l4/1wire_sht21_changes_pr (pull request #631) 
drivers/1wire: add PM hooks and unlink support to sht21 sensor (allowing hot-swappable I2C bus from 1-wire converter)

* drivers/1wire: add PM hook to 1wire bus

* drivers/1wire/ds28e17.c: i2c instance must be zeroed

* drivers/sht21: add unlink support

    Unlike most other unlink implementations in NuttX drivers, this one
    does not allow any I2C operations after unlink, making it possible to
    deallocate the I2C bus.
