mailbox: Introduce framework for mailbox Introduce common framework for client/protocol drivers and controller drivers of Inter-Processor-Communication (IPC). Client driver developers should have a look at include/linux/mailbox_client.h to understand the part of the API exposed to client drivers. Similarly controller driver developers should have a look at include/linux/mailbox_controller.h Reviewed-by: Mark Brown <broonie@linaro.org> Signed-off-by: Jassi Brar <jaswinder.singh@linaro.org>

ARM / highbank: add support for pl320 IPC The pl320 IPC allows for interprocessor communication between the highbank A9 and the EnergyCore Management Engine.

mailbox/omap: move the OMAP mailbox framework to drivers The mailbox hardware (in OMAP) uses a queued mailbox interrupt mechanism that provides a communication channel between processors through a set of registers and their associated interrupt signals by sending and receiving messages. The OMAP mailbox framework/driver code is moved to be under drivers/mailbox, in preparation for adapting to a common mailbox driver framework. This allows the build for OMAP mailbox to be enabled (it was disabled during the multi-platform support). As part of the migration from plat and mach code: - Kconfig symbols have been renamed to build OMAP1 or OMAP2+ drivers. - mailbox.h under plat-omap/plat/include has been split into a public and private header files. The public header has only the API related functions and types. - The module name mailbox.ko from plat-omap is changed to omap-mailbox.ko - The module name mailbox_mach.ko from mach-omapX is changed as mailbox_omap1.ko for OMAP1 mailbox_omap2.ko for OMAP2+ Cc: Tony Lindgren <tony@atomide.com> [gregkh@linuxfoundation.org: ack for staging part] Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Omar Ramirez Luna <omar.ramirez@copitl.com> Signed-off-by: Suman Anna <s-anna@ti.com>

mailbox/omap: consolidate OMAP mailbox driver There is no need for a separate common OMAP mailbox module now that the OMAP1 mailbox driver has been removed. So, consolidate the two individual OMAP mailbox modules into a single driver. This streamlines the driver for converting to mailbox framework. The following are the main changes: - collapse mailbox-omap2.c into omap-mailbox.c - remove omap_mbox_ops and replace the ops calls with the equivalent functionality. - simplify the sub-mailbox startup/shutdown functionality, the one-time operations are moved into probe, and the pm_runtime_get_sync and pm_runtime_put_sync can be invoked without using a configuration counter. - move all definitions from private omap_mbox.h into the source code, and eliminate this internal header. - rename some variables that used the omap2_mbox prefix with a generic omap_mbox prefix.

Mailbox: Add support for Platform Communication Channel ACPI 5.0+ spec defines a generic mode of communication between the OS and a platform such as the BMC. This medium (PCC) is typically used by CPPC (ACPI CPU Performance management), RAS (ACPI reliability protocol) and MPST (ACPI Memory power states). This patch adds PCC support as a Mailbox Controller. As of ACPI v5.1 there is no provision for clients to lookup mailbox controllers in a way that Linux expects. e.g. in DT the clients can list the mailboxes they can associate with in the DT binding and then provide a unique index to lookup a channel within a mailbox. Since the ACPI spec doesn't have anything similar, we introduce a mailbox controller specific API so that when the client calls it, we know to lookup in the context of a specific controller. This also helps in keeping a consistent interface across DT and ACPI for such drivers. This patch implements basic PCC support using the ACPI v5.1 structures. IRQ mode support will be provided as follow up patches.

mailbox: Enable BCM2835 mailbox support This mailbox driver provides a single mailbox channel to write 32-bit values to the VPU and get a 32-bit response. The Raspberry Pi firmware uses this mailbox channel to implement firmware calls, while Roku 2 (despite being derived from the same firmware tree) doesn't. The driver was originally submitted by Lubomir, based on the out-of-tree 2708 mailbox driver. Eric Anholt fixed it up for upstreaming, with the major functional change being that it now has no notion of multiple channels (since that is a firmware-dependent concept) and instead the raspberrypi-firmware driver will do that bit-twiddling in its own messages.
