| 2017-04-12 | ieee802154: ca8210: Add checks for kmalloc allocation failures | Colin Ian King | |
| Ensure we don't end up with a null pointer dereferences by checking for for allocation failures. Allocate by sizeof(*ptr) rather than the type to fix checkpack warnings. Also merge multiple lines into one line for the kmalloc call.

| 2017-04-12 | ieee802154: Add CA8210 IEEE 802.15.4 device driver | Harry Morris | |
| 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.
