Gregory Nutt	10069067c1	include/nuttx/i2c/i2c_master.h: Rename I2C_M_NORESTART to I2C_M_NOSTART since it may be used in other contexts than a repeated start. Add comments to clarilfy setup for repeated start.	2018-08-03 08:51:55 -06:00
Juha Niskanen	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.
