*	dm: core: Replace of_offset with accessor	Simon Glass	2017-02-08	-4/+4
\| \| \| \| \| \| \| \| \|	At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

*	gpio: Add driver for TI PCF8575 I2C GPIO expander	Vignesh R	2016-08-08	-0/+180
	TI's PCF8575 is a 16-bit I2C GPIO expander.The device features a 16-bit quasi-bidirectional I/O ports. Each quasi-bidirectional I/O can be used as an input or output without the use of a data-direction control signal. The I/Os should be high before being used as inputs. Read the device documentation for more details[1]. This driver is based on pcf857x driver available in Linux v4.7 kernel. It supports basic reading and writing of gpio pins.
