+ * The keyboard and touchpad controller on the MacBookAir6, MacBookPro12,
+ * MacBook8 and newer can be driven either by USB or SPI. However the USB
+ * pins are only connected on the MacBookAir6 and 7 and the MacBookPro12.
+ * All others need this driver. The interface is selected using ACPI methods:
+ *
+ * * UIEN ("USB Interface Enable"): If invoked with argument 1, disables SPI
+ * and enables USB. If invoked with argument 0, disables USB.
+ * * UIST ("USB Interface Status"): Returns 1 if USB is enabled, 0 otherwise.
+ * * SIEN ("SPI Interface Enable"): If invoked with argument 1, disables USB
+ * and enables SPI. If invoked with argument 0, disables SPI.
+ * * SIST ("SPI Interface Status"): Returns 1 if SPI is enabled, 0 otherwise.
+ * * ISOL: Resets the four GPIO pins used for SPI. Intended to be invoked with
+ * argument 1, then once more with argument 0.
+ *
+ * UIEN and UIST are only provided on models where the USB pins are connected.
+ *
+ * SPI-based Protocol
+ * ------------------
+ *
+ * The device and driver exchange messages (struct message); each message is
+ * encapsulated in one or more packets (struct spi_packet). There are two types
+ * of exchanges: reads, and writes. A read is signaled by a GPE, upon which one
+ * message can be read from the device. A write exchange consists of writing a
+ * command message, immediately reading a short status packet, and then, upon
+ * receiving a GPE, reading the response message. Write exchanges cannot be
+ * interleaved, i.e. a new write exchange must not be started till the previous
+ * write exchange is complete. Whether a received message is part of a read or
+ * write exchange is indicated in the encapsulating packet's flags field.
+ *
+ * A single message may be too large to fit in a single packet (which has a
+ * fixed, 256-byte size). In that case it will be split over multiple,
+ * consecutive packets.
