Tegra186's HSP module implements doorbells, mailboxes, semaphores, and shared interrupts. This patch provides a driver for HSP, and hooks it into the mailbox API. Currently, only doorbells are supported. Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Simon Glass <sjg@chromium.org> Acked-by: Simon Glass <sjg@chromium.org>

Enable support for the mailbox driver class. Mailboxes provide the

ability to transfer small messages and/or notifications from one
|
|
CPU to another CPU, or sometimes to dedicated HW modules. They form
|
|
the basis of a variety of inter-process/inter-CPU communication

protocols.
