I would like to ask you guys for reviews, since I didn't get any review for the first patch (adding mailbox support) yet. What's new in v3: - Three more patches, to add support for communicating with the secure firmware on the Turris Mox board. The driver for this firmware needs the mailbox driver to be able to communicate with the secure processor. Changes since v2: - changed the mailbox driver not to fail when sending a message if the firmware reports that secure processor is not ready. The firmware on EspressoBin does not indicate that it is ready in the designated register, even if it answers to commands. Print only a warning if the ready flag is not set in the FIFO_STATUS register. - added Rob's Reviewed-by tag for the mailbox dt-binding patch Marek Marek Behún (6): mailbox: Add support for Armada 37xx rWTM mailbox dt-bindings: mailbox: Document armada-3700-rwtm-mailbox binding arm64: dts: marvell: armada-37xx: add mailbox node firmware: Add Turris Mox rWTM firmware driver firmware: turris-mox-rwtm: Add sysfs documentation dt-bindings: firmware: Document cznic,turris-mox-rwtm binding .../testing/sysfs-firmware-turris-mox-rwtm | 60 +++ .../firmware/cznic,turris-mox-rwtm.txt | 19 + .../marvell,armada-3700-rwtm-mailbox.txt | 16 + arch/arm64/boot/dts/marvell/armada-37xx.dtsi | 7 + drivers/firmware/Kconfig | 14 + drivers/firmware/Makefile | 1 + drivers/firmware/turris-mox-rwtm.c | 508 ++++++++++++++++++ drivers/mailbox/Kconfig | 10 + drivers/mailbox/Makefile | 2 + drivers/mailbox/armada-37xx-rwtm-mailbox.c | 225 ++++++++ include/linux/armada-37xx-rwtm-mailbox.h | 23 + 11 files changed, 885 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-firmware-turris-mox-rwtm create mode 100644 Documentation/devicetree/bindings/firmware/cznic,turris-mox-rwtm.txt create mode 100644 Documentation/devicetree/bindings/mailbox/marvell,armada-3700-rwtm-mailbox.txt create mode 100644 drivers/firmware/turris-mox-rwtm.c create mode 100644 drivers/mailbox/armada-37xx-rwtm-mailbox.c create mode 100644 include/linux/armada-37xx-rwtm-mailbox.h
