+What:	Removing the pn544 raw driver.
+When:	3.6
+Why:	With the introduction of the NFC HCI and SHDL kernel layers, pn544.c
+	is being replaced by pn544_hci.c which is accessible through the netlink
+	and socket NFC APIs. Moreover, pn544.c is outdated and does not seem to
+	work properly with the latest Android stacks.
+	Having 2 drivers for the same hardware is confusing and as such we
+	should only keep the one following the kernel NFC APIs.

+ * - the chip will always present only one single complete frame on the bus
+ *   before triggering the interrupt
+ * - the chip will not present a new frame until we have completely read
+ *   the previous one (or until we have handled the interrupt).
+ * The tricky case is when we read a corrupted len that is less than the real
+ * len. We must detect this here in order to determine that we need to flush
+ * the bus. This is the reason why we check the crc here.
