The big update this time around is some excellent work from David Jander
who went through the fast path and really eliminated overheads, meaning
that we are seeing a huge reduction in the time spent between transfers
for single threaded clients. Benchmarking has been coming out at about a
halving of overhead which is clearly visible in system level usage that
stresses SPI like some CAN and IIO applications, especially with small
transfers. Thanks to David for taking the time to drill down into this
and push the work upstream.
Otherwise there's been a bunch of new device support and the usual
- Optimisation of the fast path, particularly around the number and
types of locking operations, from David Jander.
- Support for Arbel NPCM845, HP GXP, Intel Meteor Lake and Thunder Bay,
MediaTek MT8188 and MT8365, Microchip FPGAs, nVidia Tegra 241 and
Samsung Exynos Auto v9 and 4210.

|

The "Serial Peripheral Interface" is a low level synchronous
|
|
protocol. Chips that support SPI can have data transfer rates
|
|
up to several tens of Mbit/sec. Chips are addressed with a
|
|
controller and a chipselect. Most SPI slaves don't support
|
|
dynamic device discovery; some are even write-only or read-only.
|
|
|
|
SPI is widely used by microcontrollers to talk with sensors,
|
|
eeprom and flash memory, codecs and various other controller
|
|
chips, analog to digital (and d-to-a) converters, and more.
|
|
MMC and SD cards can be accessed using SPI protocol; and for
|
|
DataFlash cards used in MMC sockets, SPI must always be used.
|
|
|
|
SPI is one of a family of similar protocols using a four wire
|
|
interface (select, clock, data in, data out) including Microwire
|
|
(half duplex), SSP, SSI, and PSP. This driver framework should
|
|
work with most such devices and controllers.
