+config WIL6210

+	depends on CFG80211
+	depends on PCI
+	default n
+	---help---
+	  This module adds support for wireless adapter based on
+	  wil6210 chip by Wilocity. It supports operation on the
+	  60 GHz band, covered by the IEEE802.11ad standard.
+
+	  http://wireless.kernel.org/en/users/Drivers/wil6210
+
+	  If you choose to build it as a module, it will be called
+	  wil6210
+
+config WIL6210_ISR_COR
+	bool "Use Clear-On-Read mode for ISR registers for wil6210"
+	depends on WIL6210
+	default y
+	---help---
+	  ISR registers on wil6210 chip may operate in either
+	  COR (Clear-On-Read) or W1C (Write-1-to-Clear) mode.
+	  For production code, use COR (say y); is default since
+	  it saves extra target transaction;
+	  For ISR debug, use W1C (say n); is allows to monitor ISR
+	  registers with debugfs. If COR were used, ISR would
+	  self-clear when accessed for debug purposes, it makes
+	  such monitoring impossible.
+	  Say y unless you debug interrupts

+/**
+ * WMI event receiving - theory of operations
+ *
+ * When firmware about to report WMI event, it fills memory area
+ * in the mailbox and raises misc. IRQ. Thread interrupt handler invoked for
+ * the misc IRQ, function @wmi_recv_cmd called by thread IRQ handler.
+ *
+ * @wmi_recv_cmd reads event, allocates memory chunk  and attaches it to the
+ * event list @wil->pending_wmi_ev. Then, work queue @wil->wmi_wq wakes up
+ * and handles events within the @wmi_event_worker. Every event get detached
+ * from list, processed and deleted.
+ *
+ * Purpose for this mechanism is to release IRQ thread; otherwise,
+ * if WMI event handling involves another WMI command flow, this 2-nd flow
+ * won't be completed because of blocked IRQ thread.

+/**
+ * Addressing - theory of operations
+ *
+ * There are several buses present on the WIL6210 card.
+ * Same memory areas are visible at different address on
+ * the different busses. There are 3 main bus masters:
+ *  - MAC CPU (ucode)
+ *  - User CPU (firmware)
+ *  - AHB (host)
+ *
+ * On the PCI bus, there is one BAR (BAR0) of 2Mb size, exposing
+ * AHB addresses starting from 0x880000
+ *
+ * Internally, firmware uses addresses that allows faster access but
+ * are invisible from the host. To read from these addresses, alternative
+ * AHB address must be used.
+ *
+ * Memory mapping
+ * Linker address         PCI/Host address
+ *                        0x880000 .. 0xa80000  2Mb BAR0
