Cover letter [PATCH v3 0/3] Spidev usability patchset update
Hello,
this simplifies spidev to not pose as SPI driver but instead attach a character device on each SPI slave indiscriminately. This does not require spidev to be matched during driver binding and hence does not require it to be specified in devicetree.
Any SPI slave device for which a driver is not bound to start with or from which it is unbound is accessible with spidev.
Constructive comments on improving this patchset are welcome.
Thanks
Michal
