The at86rf231 frame buffer access mode read differs from all other
transceivers by only transfer one more byte after PSDU data instead
three. This difference is not evaluated in the current version of
the driver. The current change add the necessary check and read the
missing data (EQ, TRAC).

Correct bit mask for RF2XX_RX_TRAC_BIT_MASK. Current mask produce dead
code warnings when comparing to value:
RF2XX_TRX_PHY_STATE_TRAC_INVALID = 0x07

Add support to at86rf212[b] sub-giga devices. This work enables use of
pages 0, 2 and 5 in accordance with IEEE-802.15.4/2003/2006/2011. The
proprietary speeds can be object of future work.
Note: It is recommended that user define a power table for better
performance, low emissions and to save power. A reference power table
can be found in the datasheet and should be used for tests only and
not on a final product.

Add initial Atmel at86rf2xx transceiver driver. This driver uses device
tree to configure the physical interface. The driver had capability to
use multiple transceiver and systems with multiple bands can be used.
With this, 2.4GHz ISM and Sub-Giga can be used simultaneous.
Below a valid DT example. This samples assume same SPI port with two
transceivers.
&spi0 {
status = "okay";
label = "SPI_RF2XX";
cs-gpios = <&porta 31 0 &porta 30 0>;
rf2xx@0 {
compatible = "atmel,rf2xx";
reg = <0x0>;
label = "RF2XX_0";
spi-max-frequency = <7800000>;
irq-gpios = <&portb 2 0>;
reset-gpios = <&porta 3 0>;
slptr-gpios = <&portb 3 0>;
status = "okay";
};
rf2xx@1 {
compatible = "atmel,rf2xx";
reg = <0x1>;
label = "RF2XX_1";
spi-max-frequency = <7800000>;
irq-gpios = <&portb 4 0>;
reset-gpios = <&porta 4 0>;
slptr-gpios = <&portb 4 0>;
status = "okay";
};
};
At the moment driver assume two transceiver are enouth for majority of
appications. Sub-Giga band will be enabled in future.
