I've addressed your comments with the following changes from v2 to v3: - removed dma barriers since the mbox client will take care of these - moved the of_device_id table and related code to the bottom of the file - removed of_xlate - dropped clock handling from the code and the binding since we now understand that these are actually power domains Changes from v1 to v2: - switched to txdone_irq instead of introducing a new mode - switched to a threaded interrupt handler for receiving messages - added co-processor examples to the device tree binding - reformatted the register defines and clarified multiple comments Best, Sven Sven Peter (2): dt-bindings: mailbox: Add Apple mailbox bindings mailbox: apple: Add driver for Apple mailboxes .../bindings/mailbox/apple,mailbox.yaml | 79 ++++ MAINTAINERS | 3 + drivers/mailbox/Kconfig | 12 + drivers/mailbox/Makefile | 2 + drivers/mailbox/apple-mailbox.c | 374 ++++++++++++++++++ include/linux/apple-mailbox.h | 18 + 6 files changed, 488 insertions(+) create mode 100644 Documentation/devicetree/bindings/mailbox/apple,mailbox.yaml create mode 100644 drivers/mailbox/apple-mailbox.c create mode 100644 include/linux/apple-mailbox.h -- 2.25.1
