spi: tools: Add include folder to .gitignore (2026-02-09 12:27:31 +0000)
----------------------------------------------------------------
spi: Updates for v7.0
The highlight here is that David Lechner has added support for multi-lane
SPI devices. Unlike the existing dual/quad SPI support this is for
devices (typically ADCs/DACs) which support multiple independent data
streams over multiple data lanes, instead of sending one data stream N
times as fast they simultaneously transfer N different data streams.
This is very similar to the case where multiple devices are grouped
together but in this case it's a single device in a way that's visible
to software.
Otherwise there's been quite a bit of work on existing drivers, both
cleanup and feature improvement, and a reasonable collection of new
drivers.
- Support for multi-lane SPI devices.
- Preparatory work for some memory mapped flash improvements that will
happen in the MTD subsystem.
- Several conversions to fwnode APIs.
- A bunch of cleanup and hardening work on the ST drivers.
- Support for DMA mode on Renesas RZV2H and i.MX target mode.
- Support for ATCSPI200, AXIADO AX300, NXP XPI and Renesas RZ/N1.
