Subject: dt-bindings: Add pxa1928 clock binding

This adds the clock binding documentation for the Marvell PXA1928 SOC.
The PXA1928 has 3 clock control blocks for different subsystems of the
chip.

+* Marvell PXA1928 Clock Controllers
+
+The PXA1928 clock subsystem generates and supplies clock to various
+controllers within the PXA1928 SoC. The PXA1928 contains 3 clock controller
+blocks called APMU, MPMU, and APBC roughly corresponding to internal buses.
+
+Required Properties:
+
+- compatible: should be one of the following.
+  - "marvell,pxa1928-apmu" - APMU controller compatible
+  - "marvell,pxa1928-mpmu" - MPMU controller compatible
+  - "marvell,pxa1928-apbc" - APBC controller compatible
+- reg: physical base address of the clock controller and length of memory mapped
+  region.
+- #clock-cells: should be 1.
+- #reset-cells: should be 1.
+
+Each clock is assigned an identifier and client nodes use the clock controller
+phandle and this identifier to specify the clock which they consume.
+
+All these identifiers can be found in <dt-bindings/clock/marvell,pxa1928.h>.

Subject: clk: meson: Add support for Meson clock controller

This patchset adds the infrastructure for registering and managing the
core clocks found on Amlogic MesonX SoCs. In particular:

- PLLs
- CPU clock
- Fixed rate clocks, fixed factor clocks, ...

Subject: clk: cygnus: add clock support for Broadcom Cygnus

The Broadcom Cygnus SoC is architected under the iProc architecture. It
has the following PLLs: ARMPLL, GENPLL, LCPLL0, MIPIPLL, all dervied
from an onboard crystal. Cygnus also has various ASIU clocks that are
derived directly from the onboard crystal.

Subject: clk: add lpc18xx cgu clk driver

Add driver for NXP LPC18xx/43xx Clock Generation Unit (CGU). The CGU
contains several clock generators and output stages that route the
clocks either directly to peripherals or to a Clock Control Unit
(CCU).

Subject: clk: add lpc18xx ccu clk driver

Add driver for NXP LPC18xx/43xx Clock Control Unit (CCU). The CCU
provides fine grained gating of most clocks present in the SoC.
