This has been a fairly quiet release for SPI, though it is likely that the next release will have some big changes as there's some preparatory work for multiple chip select support gone in - the rest of the code is on the list but will need to be rebased onto -rc1. Otherwise there's a couple of new tunables for chip select timings, some new devices and smaller device specific updates and fixes. - Support for configuring the hold and minimum inactive times for chip selects. - Beginnings of support for supporting devices which have multiple chip selects on a single device. - Support for newer Broadcom HSSPI and Intel controllers, Silicon Labs EM3581 and SI3210. There is a simple add/add conflict in MAINTAINERS with the I2C tree. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmPzcwwACgkQJNaLcl1U h9B3egf/Yo9cnaB473bDfIOmx/AAKU33U059n27CKdbkOy/pqP7zTaurne0aTFDD SsJh9+Akmb4aBQTTT8RRn9zLho6pX2lUrtFDKjbVB1DM/E7Bad8EsMlqBGLpGUNs GmEsa99XtUlcEeORq3HIObZ2G2v+Jy0IiidCUyTo48JZBAV3pvI5J8SPUwpWMfqM fq2U5kCXjxlheQsa4FLzMqnWS91D3H58XFboPQJ2y29sqWSq2OnD/mt9XQVHcvbg zzL/EfOYoIpw8c9Qf2ZPoLDzRZAdVhugFoMRKccW8OD/v5Rfaf02vhtwfz3G7JpV So+eEIVSJniavgpBMnUY4tqTOxDe/g== =xz0n -----END PGP SIGNATURE----- Merge tag 'spi-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi updates from Mark Brown: "This has been a fairly quiet release for SPI, though it is likely that the next release will have some big changes as there's some preparatory work for multiple chip select support gone in - the rest of the code is on the list but will need to be rebased onto -rc1.

|
|
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.
