2016-12-12	i2c: fsl-lpi2c: read lpi2c fifo size in probe()	Gao Pan	1	-9/+15
	The lpi2c fifo size is a read only parameter resides Parameter Register. It's better to read lpi2c tx/rx fifo size in probe() other than just define a macro for it.

2016-12-02	i2c: imx-lpi2c: add low power i2c bus driver	Gao Pan	1	-0/+646
	This patch adds lpi2c bus driver to support new i.MX products which use lpi2c instead of the old imx i2c. The lpi2c can continue operating in stop mode when an appropriate clock is available. It is also designed for low CPU overhead with DMA offloading of FIFO register accesses.
