2016-11-18mailbox: tegra-hsp: Use after free in tegra_hsp_remove_doorbells()Dan Carpenter1-2/+2
We have to use the _safe version of list_for_each() because we're freeing the pointer as we go along. (This might not show up testing depending on what config options you have enabled).

2016-11-18mailbox: Add Tegra HSP driverThierry Reding1-0/+479
This driver exposes a mailbox interface for interprocessor communication using the Hardware Synchronization Primitives (HSP) module's doorbell mechanism. There are multiple HSP instances and they provide additional features such as shared mailboxes, shared and arbitrated semaphores. A driver for a remote processor can use the mailbox client provided by the HSP driver and build an IPC protocol on top of this synchronization mechanism. Based on work by Joseph Lo <josephl@nvidia.com>. Acked-by: Jassi Brar <jaswinder.singh@linaro.org> Signed-off-by: Thierry Reding <treding@nvidia.com>
