cc2520: move to gpio descriptors cc2520 supports both probing from static platform_data and from devicetree, but there have never been any definitions of the platform data in the mainline kernel, so it's safe to assume that only the DT path is used. After folding cc2520_platform_data into the driver itself, the GPIO handling can be simplified by moving to the modern gpiod interface.

spi: make remove callback a void function The value returned by an spi driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

ieee802154: cc2520: Check CRC & add promiscuous This patch adds checking the "CRC_OK" bit at the end of packets coming from the CC2520 radio. It also adds support for putting the radio in promiscuous mode (in which packets are not dropped if the CRC fails). In promiscuous mode the AUTOCRC flag is cleared so that the driver can pass the received CRC to the monitors. The radio now defaults to frame filtering (checking that the destination and PANID in the incoming packet matches the local node). This matches the other 15.4 radios and is what a user would expect to be the default. Other changes: 1. Adds LQI calculation 2.

cc2520: Add support for CC2591 amplifier. The TI CC2521 is an RF power amplifier that is designed to interface with the CC2520. Conveniently, it directly interfaces with the CC2520 and does not require any pins to be connected to a microcontroller/processor. Adding a CC2591 increases the CC2520's range, which is useful for border router and other wall-powered applications. Using the CC2591 with the CC2520 requires configuring the CC2520 GPIOs that are connected to the CC2591 to correctly set the CC2591 into TX and RX modes. Further, TI recommends that the CC2520_TXPOWER and CC2520_AGCCTRL1 registers are set differently to maximize the CC2591's performance. These settings are covered in TI Application Note AN065. This patch adds an optional `amplified` field to the cc2520 entry in the device tree. If present, the CC2520 will be configured to operate with a CC2591. The expected pin mapping is: CC2520 GPIO0 --> CC2591 EN CC2520 GPIO5 --> CC2591 PAEN Signed-off-by: Brad Campbell <bradjc5@gmail.com> Acked-by: Varka Bhadram <varkabhadram@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
