This series is basically to deprecate using ctrl-module property and use
corresponding syscon properties to program the control module registers.

Changes from v3:
*) Renamed 'tisyscon@1c24' node to 'scm_conf@1c24'

Changes from v2:
No changes.

Changes from v1:
*) Squashed the patches that replaces "ctrl-module" with
   "syscon-phy-power"
*) Added "syscon-phy-power" for SATA dt node in OMAP5 which was missed
   earlier
*) removed _ARM: dts: omap4: Use "syscon-otghs" instead of "ctrl-module"
   in USB node_. It will be done later.

Changes from [1] in PHY patches include
*) cleanup ti_pipe3_probe
*) have mask, power_on and power_off values in usb_phy_data for
   omap-usb2 phy

This series should be merged only after [2]
Kishon Vijay Abraham I (4):
  ARM: dts: dra7: Add dt node for the sycon pcie
  ARM: dts: dra7: Use "syscon-phy-power" and "syscon-pcs" in PCIe PHY
    node
  ARM: dts: dra7: Use "ti,dra7x-usb2-phy2" compatible string for USB2
    PHY2
  ARM: dts: <am4372/dra7/omap5>: Use "syscon-phy-power" instead of
    "ctrl-module"

Add new device tree node for the control module register space where
PCIe registers are present.

Add "syscon-phy-power" property and "syscon-pcs" property which can
be used to perform the control module initializations and remove
the deprecated "ctrl-module" property from PCIe PHY dt nodes.

Phandle to "sysclk" clock node is also added to the PCIe PHY node
since some of the syscon initializations is based on system clock
frequency.

Since "omap_control_pcie1phy" and "omap_control_pcie2phy" devicetree
nodes are no longer used, remove it.

Add "syscon-phy-power" property and remove the deprecated "ctrl-module"
property from SATA and USB PHY node. Also remove the unused control
module dt nodes.
