Each Mailbox is divided up into 4 instances which consist of 32 channels. Messages are passed between the application and co-processors using shared memory areas. Also included in the set is an example Client which should be generic enough to use as a testing environment for all Mailbox IPs which use shared memory to pass messages. With a small change, it should also be able to test more extravagant implementations too. v1 => v2: - New MACRO() to obtain base address for a given instance - Move locking into the structure it protects - Stop checking for 'ready' state when sending data - Don't clear channel data (that belongs to the API) - #define register offsets instead of providing via pdata - Register driver with module_platform_driver() Lee Jones (6): mailbox: dt: Supply bindings for ST's Mailbox IP mailbox: dt-bindings: Add shared [driver <=> device tree] defines mailbox: Add support for ST's Mailbox IP ARM: STi: stih407-family: Add nodes for Mailbox mailbox: Add generic mechanism for testing Mailbox Controllers ARM: STi: DT: STiH407: Enable Mailbox testing facility .../devicetree/bindings/mailbox/sti-mailbox.txt | 53 +++ arch/arm/boot/dts/stih407-family.dtsi | 40 ++ drivers/mailbox/Kconfig | 14 + drivers/mailbox/Makefile | 4 + drivers/mailbox/mailbox-sti.c | 527 +++++++++++++++++++++ drivers/mailbox/mailbox-test.c | 210 ++++++++ include/dt-bindings/mailbox/mailbox.h | 14 + 7 files changed, 862 insertions(+) create mode 100644 Documentation/devicetree/bindings/mailbox/sti-mailbox.txt create mode 100644 drivers/mailbox/mailbox-sti.c create mode 100644 drivers/mailbox/mailbox-test.c create mode 100644 include/dt-bindings/mailbox/mailbox.h -- 1.9.1
