From Linus Walleij:

Nomadik DT and clock work:
- Lee Jones' pinctrl compat ontology patches
- A real clock driver for the Nomadik, 100% DT-based
- Device tree changes for the Nomadik clocks

* tag 'nomadik-dt-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik:
  ARM: nomadik: add the new clocks to the device tree
  clk: nomadik: implement the Nomadik clocks properly
  pinctrl/nomadik: Standardise Pinctrl compat string for Nomadik based platforms
  ARM: nomadik: Standardise Nomadik STN8815 based Pinctrl compat string in the DTS

+ST Microelectronics Nomadik SRC System Reset and Control
+
+This binding uses the common clock binding:
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+The Nomadik SRC controller is responsible of controlling chrystals,
+PLLs and clock gates.
+
+Required properties for the SRC node:
+- compatible: must be "stericsson,nomadik-src"
+- reg: must contain the SRC register base and size
+
+Optional properties for the SRC node:
+- disable-sxtalo: if present this will disable the SXTALO
+  i.e. the driver output for the slow 32kHz chrystal, if the
+  board has its own circuitry for providing this oscillator
+- disable-mxtal: if present this will disable the MXTALO,
+  i.e. the driver output for the main (~19.2 MHz) chrystal,
+  if the board has its own circuitry for providing this
+  osciallator
+
+
+PLL nodes: these nodes represent the two PLLs on the system,
+which should both have the main chrystal, represented as a
+fixed frequency clock, as parent.
+
+Required properties for the two PLL nodes:
+- compatible: must be "st,nomadik-pll-clock"
+- clock-cells: must be 0
+- clock-id: must be 1 or 2 for PLL1 and PLL2 respectively
+- clocks: this clock will have main chrystal as parent
+
+
+HCLK nodes: these represent the clock gates on individual
+lines from the HCLK clock tree and the gate for individual
+lines from the PCLK clock tree.
+
+Requires properties for the HCLK nodes:
+- compatible: must be "st,nomadik-hclk-clock"
+- clock-cells: must be 0
+- clock-id: must be the clock ID from 0 to 63 according to
+  this table:
