2017-01-12ieee802154: atusb: fix driver to work with older firmware versionsStefan Schmidt1-9/+4
After the addition of the frame_retries callback we could run into cases where a ATUSB device with an older firmware version would now longer be able to bring the interface up. We keep this functionality disabled now if the minimum firmware version for this feature is not available.

2017-01-12at86rf230: Allow slow GPIO pins for "rstn"Andrey Smirnov1-2/+2
Driver code never touches "rstn" signal in atomic context, so there's no need to implicitly put such restriction on it by using gpio_set_value to manipulate it. Replace gpio_set_value to gpio_set_value_cansleep to fix that. As a an example of where such restriction might be inconvenient, consider a hardware design where "rstn" is connected to a pin of I2C/SPI GPIO expander chip.

2016-04-20at86rf230: increase sleep to off timingsAlexander Aring1-3/+3
I expierenced when setting channel while sleep mode it didn't changed the channel inside the hardware registers. Then I got another report of an user which has similar issues. I increased the sleep to off state change timing, which is according at86rf233 at maximum 1000 us. After this change I got no similar effects again. I tried another option to wait on AWAKE_END irq, which can be used to wait until the transceiver is awaked. I tested it and the IRQ took 4 seconds after starting state change. I don't believe it takes 4 seconds to go into the TRX_OFF state from SLEEP state. The alternative is to increase the timings which seems to work.

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.
