spi: rpc-if: Add resume support for RZ/G3E (2025-09-23 10:57:52 +0200)
----------------------------------------------------------------
spi: Updates for v6.18
There's one big core change in this release, Jonas Gorski has addressed
the issues with multiple chip selects which makes things more robust and
stable. Otherwise there's quite a bit of driver work, as well as some
new drivers several existing drivers have had quite a bit of work done
on them.
Possibly the most interesting thing is the VirtIO driver, this is
apparently useful for some automotive applications which want to keep as
small and robust a host system as they can, moving less critical
functionality into guests.
- James Clark has done some substantial updates on the Freescale DSPI
driver, porting in code from the BSP and building onm top of that to
fix some bugs and increase performance.
- Jonas Gorski has fixed the issues with handling multple chip selects,
making things more robust and scalable.
- Support for higher performance modes in the NXP FSPI driver from
Haibo Chen.
- Removal of the obsolete S3C2443 driver, the underlying SoC support
has been removed from the kernel.
- Support for Amlogic AL113L2, Atmel SAMA7D65 and SAM9x7 and for VirtIO
controllers.
