The Amlogic SoC embeds a standalone CEC controller, this patch adds a driver for such controller. The controller does not need HPD to be active, and could support up to max 5 logical addresses, but only 1 is handled since the Suspend firmware can make use of this unique logical address to wake up the device. The Suspend firmware configuration will be added in an other patchset. Changes since v1 at [1] : - add timeout to wait busy, with error return - handle busy error in all read/write operations - add CEC_CAP_PASSTHROUGH - add bindings ack [1] https://lkml.kernel.org/r/1499336870-24118-1-git-send-email-narmstrong@baylibre.com Neil Armstrong (2): platform: Add Amlogic Meson AO CEC Controller driver dt-bindings: media: Add Amlogic Meson AO-CEC bindings .../devicetree/bindings/media/meson-ao-cec.txt | 28 + drivers/media/platform/Kconfig | 11 + drivers/media/platform/Makefile | 2 + drivers/media/platform/meson/Makefile | 1 + drivers/media/platform/meson/ao-cec.c | 781 +++++++++++++++++++++ 5 files changed, 823 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/meson-ao-cec.txt create mode 100644 drivers/media/platform/meson/Makefile create mode 100644 drivers/media/platform/meson/ao-cec.c -- 1.9.1
