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>
