The Virtio SPI (Serial Peripheral Interface) device is a virtual SPI controller that allows the driver to operate and use the SPI controller under the control of the host, either a physical SPI controller, or an emulated one.
changelog: ========= v9->v10: - add explanation of CPHA and CPOL - update the statement of bits_per_word_mask when it is set as 0 v8->v9: - add explanation of bits_per_word_mask in config space v7->v8: - change device to host v6->v7: - fix the format problems and syntax problems v5->v6: - use driver/device instead guest/host - add the definition of some terminologies - use controller instead of master throughout the spec - add buffer length validation for full-duplex transfer v4->v5: - use controller instead of master - fix indentation issue - extend the config space to expose the backend supported features - add another result value to indicate parameter error - add device and driver requirement about parameter checking v3->v4: - fix the spell errors - bus_num is not SOC-specific, remove it - add driver requirement to deal with the situation that the cs delay parameters are not 0 but the backend doesn't support cs timing setting v2->v3 - remove unnecessary statements and driver implementation details - add the parameters about cs timing delay and transfer delay - use "le32" instead of "u32" - swap the rx_buf and tx_buf in the request format - add the parameters about transfer bit width v1->v2: - explain SPI when it is firstly used - update the ambiguous expression of virtqueue v0->v1: - add definition of abbreviation SPI - remove the ID Haixu Cui (2): content: Rename SPI master to SPI controller virtio-spi: add the device specification conformance.tex | 12 +- content.tex | 3 +- device-types/spi/description.tex | 286 ++++++++++++++++++++++++ device-types/spi/device-conformance.tex | 7 + device-types/spi/driver-conformance.tex | 7 + 5 files changed, 310 insertions(+), 5 deletions(-) create mode 100644 device-types/spi/description.tex create mode 100644 device-types/spi/device-conformance.tex create mode 100644 device-types/spi/driver-conformance.tex -- 2.17.1 --------------------------------------------------------------------- To unsubscribe, e-mail: virtio-dev-unsubscr...@lists.oasis-open.org For additional commands, e-mail: virtio-dev-h...@lists.oasis-open.org
