This is the bulk of GPIO changes for the v3.19 series: - A new API that allows setting more than one GPIO at the time. This is implemented for the new descriptor-based API only and makes it possible to e.g. toggle a clock and data line at the same time, if the hardware can do this with a single register write. Both consumers and drivers need new calls, and the core will fall back to driving individual lines where needed. Implemented for the MPC8xxx driver initially. - Patched the mdio-mux-gpio and the serial mctrl driver that drives modems to use the new multiple-setting API to set several signals simultaneously. - Get rid of the global GPIO descriptor array, and instead allocate descriptors dynamically for each GPIO on a certain GPIO chip. This moves us closer to getting rid of the limitation of using the global, static GPIO numberspace. - New driver and device tree bindings for 74xx ICs. - New driver and device tree bindings for the VF610 Vybrid. - Support the RCAR r8a7793 and r8a7794. - Guidelines for GPIO device tree bindings trying to get things a bit more strict with the advent of combined device properties. - Suspend/resume support for the MVEBU driver. - A slew of minor fixes and improvements.
