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 or the API to pass messages. With small changes, it should also be able to test more extravagant implementations. v2 => v3: - Controller - Shared (DT <=> Device Driver) defines removed - Return actual error codes instead of NULL in xlate() - Not passing 'direction' configuration via DT anymore - Removed all accompanying configuration checking code - Test F/W - Allow Rx-only and Tx-only controllers to be tested - Cater for controllers requiring pre-Tx 'signal' to be sent - Supply 'wr-' message debugfs file - When written to, will Tx message through Mailbox Framework - When read from, will print out a hexdump of Rx'ed message 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 (5): mailbox: dt: Supply bindings for ST's Mailbox IP 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 | 52 +++ arch/arm/boot/dts/stih407-family.dtsi | 42 ++ drivers/mailbox/Kconfig | 14 + drivers/mailbox/Makefile | 4 + drivers/mailbox/mailbox-sti.c | 516 +++++++++++++++++++++ drivers/mailbox/mailbox-test.c | 361 ++++++++++++++ 6 files changed, 989 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 -- 1.9.1
