Hi All,

This patch series adds reset controller support for STi SOC series STiH415 and
STiH416. It adds support for both power down reset and soft reset controllers.
On STi series SOCs reset lines are wired up to system configuration registers.
Most of the IPs on STi SOCs are left in reset state, so this driver is very
important for other drivers to use the IPs.

Patch 01: Adds reset controller based on system configuration registers via

Patch 02, 03: adds STiH415 and STiH416 reset controller drivers.

Patch 04, 05: adds STiH415 and STiH416 soft reset controllers.

The final patch 06 selects reset controller in mach-sti Kconfig.

I would like get this driver in to 3.15, so that its possible to add dt
support for other IPs with reset lines. Without this patchset its impossible
to add DT support to IPs with reset lines as reset line definition is in
common header file in include/dt-bindings/.

This reset controller will be used by gmac, i2c and st-ir drivers.


Changes since v1:
	- Added all the softreset lines.
	- rebased to v3.14-rc1.
