    Subject[PATCH 05/11] Documentation: bindings: move the Berlin reset documentation
    Date
    The Berlin reset documentation was part of the Marvell Berlin SoC
    documentation because the Berlin reset configuration was inside the chip
    controller. With the recent rework of the chip and system controller
    handling (now an MFD driver registers all sub-devices of the two soc and
    system controller nodes and each device has its own sub-node), the
    documentation of the Berlin reset driver can be moved to the generic
    reset documentation directory.

    +Marvell Berlin reset controller
    +===============================
    +
    +Please also refer to reset.txt in this directory for common reset
    +controller binding usage.
    +
    +The reset controller node must be a sub-node of the chip controller
    +node on Berlin SoCs.
    +
    +Required properties:
    +- compatible: should be "marvell,berlin2-reset"
    +- #reset-cells: must be set to 2
    +
    +Example:
    +
    +chip_rst: reset {
    + compatible = "marvell,berlin2-reset";
    + #reset-cells = <2>;
    +};
    +
    +&usb_phy0 {
    + resets = <&chip_rst 0x104 12>;
