[PATCH v8 00/13] ARM: berlin: USB support

[Antoine Tenart]

This series adds the support for ChipIdea USB2 (ci13xxx) controllers,
the USB PHYs of the Marvell Berlin SoCs and also adds a reset
controller for these SoCs.

The reset controller is used by the PHY driver and shares the
existing chip controller node with the clocks and one pin controller.

The Marvell Berlin USB controllers are host only on the BG2Q and are
compatible with USB ChipIdea. We here add a glue to use the available
common functions for this kind of controllers, and add a generic USB2
ChipIdea driver. A PHY driver is also added to control the USB PHY.

This series applies on top of Peter Chen's ci-for-usb-next branch[1]
containing the generic PHY support in the USB framework[2].

Patches 1-4 should already have been taken by Sebastian.

Changes since v7:
	- rebased on top of the latest CI for-next branch of Peter[1]
	- removed CI_HDRC_REQUIRE_TRANSCEIVER
	- added a missing tested-by
	- some cosmetic fixes and a commit message reword

Changes since v6:
        - removed ci_hdrc_usb2_dt_probe
        - fixed a bug in the ChipIdea core for PHY handling
        - called unconditionally dma_set_mask_and_coherent()

Changes since v5:
        - added a missing header in ci_hdrc_usb2

Changes since v4:
        - fixed the error handling of ci_hdrc_usb2_probe()

Changes since v3:
        - removed the DMA mask property
        - moved the clock handling in the common probe function
        - fixed the documentation for the USB2 ChipIdea USB PHY binding
        - made sure the reset bit is 0-31 in the reset driver

Changes since v2:
        - moved the PHY driver to the generic PHY framework
        - changed the compatible to 'chipidea,usb2'
        - added a property to set the DMA mask in the USB2 CI driver
        - separated dt specific calls in the CI probing function
        - rebased on top of the generic PHY support for CI[2]

Changes since v1:
        - made the Berlin CI USB driver a generic one
        - added support to custom offset for the reset register
        - added fixed regulators to support supply the VBUS
        - modified the PHY driver to support the one one the BG2CD as
          well
        - documented the reset properties
        - added bindings for the BG2CD
        - cosmetic fixes
