Add the basic structure of the SiPEED SLogic Combo8 logic analyzer driver: USB device scanning, device open/close and the driver registration with the supported scan and device options. Signed-off-by: Lindolfo Meira <meiraa@gmail.com>
Implement the acquisition engine: the vendor USB protocol to start and stop streaming, the bulk-transfer handling with the fixed-size transfer buffer, and the bit expansion for the packed 2ch/4ch capture modes. Signed-off-by: Lindolfo Meira <meiraa@gmail.com>
…e limits Add support for configuring the samplerate, channel count, capture limits and software trigger. The capture mode (channel count) always follows the selected samplerate: lowering the rate widens the capture (160MHz -> 2ch, 80MHz -> 4ch, 40MHz -> 8ch) and raising it narrows it. Manually selecting a channel that requires a bigger mode raises the mode and clamps the samplerate down to that mode's maximum, stating the limit in a warning. The full samplerate range is always listed and the effective rate is reported through a META packet at the start of every acquisition so frontends can stay in sync.

This series adds a driver for the SiPEED SLogic Combo8, an 8-channel USB logic analyzer. It can capture at up to 160MHz (with 2 channels), 80MHz (4 channels) or 40MHz (8 channels), using a software trigger.
Patch 1 adds the driver skeleton (scan, open/close, registration), patch 2 implements the acquisition engine over the vendor USB protocol, and patch 3 adds the configurable options: the samplerate, channel count, capture limits and software trigger.
The channel count (capture mode) is tied to the samplerate and always follows it: lowering the rate widens the capture (160MHz -> 2ch, 80MHz -> 4ch, 40MHz -> 8ch) and raising it narrows it. Manually selecting a channel that requires a bigger mode raises the mode and clamps the samplerate down to that mode's maximum, stating the limit in a warning. The full samplerate range is always listed, and the effective rate is reported through a META packet at the start of every acquisition so frontends (e.g. PulseView) can stay in sync.
