+* Texas Instruments TRF7970A RFID/NFC/15693 Transceiver
+
+Required properties:
+- compatible: Should be "ti,trf7970a".
+- spi-max-frequency: Maximum SPI frequency (<= 2000000).
+- interrupt-parent: phandle of parent interrupt handler.
+- interrupts: A single interrupt specifier.
+- ti,enable-gpios: Two GPIO entries used for 'EN' and 'EN2' pins on the
+  TRF7970A.
+- vin-supply: Regulator for supply voltage to VIN pin
+
+Optional SoC Specific Properties:
+- pinctrl-names: Contains only one value - "default".
+- pintctrl-0: Specifies the pin control groups used for this controller.
+
+Example (for ARM-based BeagleBone with TRF7970A on SPI1):
+
+&spi1 {
+	status = "okay";
+
+	nfc@0 {
+		compatible = "ti,trf7970a";
+		reg = <0>;
+		pinctrl-names = "default";
+		pinctrl-0 = <&trf7970a_default>;
+		spi-max-frequency = <2000000>;
+		interrupt-parent = <&gpio2>;
+		interrupts = <14 0>;
+		ti,enable-gpios = <&gpio2 2 GPIO_ACTIVE_LOW>,
+				  <&gpio2 5 GPIO_ACTIVE_LOW>;
+		vin-supply = <&ldo3_reg>;
+		status = "okay";
+	};
+};

+/* There are 3 ways the host can communicate with the trf7970a:
+ * parallel mode, SPI with Slave Select (SS) mode, and SPI without
+ * SS mode.  The driver only supports the two SPI modes.
+ *
+ * The trf7970a is very timing sensitive and the VIN, EN2, and EN
+ * pins must asserted in that order and with specific delays in between.
+ * The delays used in the driver were provided by TI and have been
+ * confirmed to work with this driver.
+ *
+ * Timeouts are implemented using the delayed workqueue kernel facility.
+ * Timeouts are required so things don't hang when there is no response
+ * from the trf7970a (or tag).  Using this mechanism creates a race with
+ * interrupts, however.  That is, an interrupt and a timeout could occur
+ * closely enough together that one is blocked by the mutex while the other
+ * executes.  When the timeout handler executes first and blocks the
+ * interrupt handler, it will eventually set the state to IDLE so the
+ * interrupt handler will check the state and exit with no harm done.
+ * When the interrupt handler executes first and blocks the timeout handler,
+ * the cancel_delayed_work() call will know that it didn't cancel the
+ * work item (i.e., timeout) and will return zero.  That return code is
+ * used by the timer handler to indicate that it should ignore the timeout
+ * once its unblocked.
+ *
+ * Aborting an active command isn't as simple as it seems because the only
+ * way to abort a command that's already been sent to the tag is so turn
+ * off power to the tag.  If we do that, though, we'd have to go through
+ * the entire anticollision procedure again but the digital layer doesn't
+ * support that.  So, if an abort is received before trf7970a_in_send_cmd()
+ * has sent the command to the tag, it simply returns -ECANCELED.  If the
+ * command has already been sent to the tag, then the driver continues
+ * normally and recieves the response data (or error) but just before
+ * sending the data upstream, it frees the rx_skb and sends -ECANCELED
+ * upstream instead.  If the command failed, that error will be sent
+ * upstream.
+ *
+ * When recieving data from a tag and the interrupt status register has
+ * only the SRX bit set, it means that all of the data has been received
+ * (once what's in the fifo has been read).  However, depending on timing
+ * an interrupt status with only the SRX bit set may not be recived.  In
+ * those cases, the timeout mechanism is used to wait 5 ms in case more
+ * data arrives.  After 5 ms, it is assumed that all of the data has been
+ * received and the accumulated rx data is sent upstream.  The
+ * 'TRF7970A_ST_WAIT_FOR_RX_DATA_CONT' state is used for this purpose
+ * (i.e., it indicates that some data has been received but we're not sure
+ * if there is more coming so a timeout in this state means all data has
+ * been received and there isn't an error).  The delay is 5 ms since delays
+ * over 2 ms have been observed during testing (a little extra just in case).
+ *
+ * Type 2 write and sector select commands respond with a 4-bit ACK or NACK.
+ * Having only 4 bits in the FIFO won't normally generate an interrupt so
+ * driver enables the '4_bit_RX' bit of the Special Functions register 1
+ * to cause an interrupt in that case.  Leaving that bit for a read command
+ * messes up the data returned so it is only enabled when the framing is
+ * 'NFC_DIGITAL_FRAMING_NFCA_T2T' and the command is not a read command.
+ * Unfortunately, that means that the driver has to peek into tx frames
+ * when the framing is 'NFC_DIGITAL_FRAMING_NFCA_T2T'.  This is done by
+ * the trf7970a_per_cmd_config() routine.
+ *
+ * ISO/IEC 15693 frames specify whether to use single or double sub-carrier
+ * frequencies and whether to use low or high data rates in the flags byte
+ * of the frame.  This means that the driver has to peek at all 15693 frames
+ * to determine what speed to set the communication to.  In addition, write
+ * and lock commands use the OPTION flag to indicate that an EOF must be
+ * sent to the tag before it will send its response.  So the driver has to
+ * examine all frames for that reason too.
+ *
+ * It is unclear how long to wait before sending the EOF.  According to the
+ * Note under Table 1-1 in section 1.6 of
+ * http://www.ti.com/lit/ug/scbu011/scbu011.pdf, that wait should be at least
+ * 10 ms for TI Tag-it HF-I tags; however testing has shown that is not long
+ * enough.  For this reason, the driver waits 20 ms which seems to work
+ * reliably.
