title: Samsung Exynos Mailbox Controller

maintainers:
  - Tudor Ambarus <tudor.ambarus@linaro.org>

description:
  The Samsung Exynos mailbox controller, used on Google GS101 SoC, has 16 flag
  bits for hardware interrupt generation and a shared register for passing
  mailbox messages. When the controller is used by the ACPM interface
  the shared register is ignored and the mailbox controller acts as a doorbell.
  The controller just raises the interrupt to the firmware after the
  ACPM interface has written the message to SRAM.

      For "microchip,sbi-ipc", the cell represents the global "logical"

    description: >
      Represents the enable/disable state of the bi-directional IHC
      channels within the MIV-IHC IP configuration.

      A bit set to '1' indicates that the corresponding channel is disabled,
      and any read or write operations to that channel will return zero.

      A bit set to '0' indicates that the corresponding channel is enabled
      and will be accessible through its dedicated address range registers.

      The actual enable/disable state of each channel is determined by the
      IP block’s configuration.
