ieee802154: Add CA8210 IEEE 802.15.4 device driver (ded845a7) · Commits · 戴 / test

Add driver source and config for softMAC implementation of Cascoda's CA8210 IEEE 802.15.4 transceiver device. The driver mimics a common PHY-only implementation despite the CA8210 being a hardMAC device which exposes a SAP interface to the fully integrated MAC. The chip is a modem-only device with an integrated processor which runs the 802.15.4 MAC. The chip communicates via full-duplex SPI with additional pins for NIRQ and NRESET. The chip can also output its 16MHz clock to a GPIO with a configurable divider. The driver can be configured to implement a debugfs node that provides access to the SAP-based API to drive mechanisms not currently supported by the standard kernel interface. Signed-off-by:
