+The GRCAN and CRHCAN CAN controllers are available in the GRLIB VHDL IP core
+library.
+
+Note: These properties are built from the AMBA plug&play in a Leon SPARC system
+(the ordinary environment for GRCAN and GRHCAN). There are no dts files for
+sparc.
+
+Required properties:
+
+- name : Should be "GAISLER_GRCAN", "01_03d", "GAISLER_GRHCAN" or "01_034"
+
+- reg : Address and length of the register set for the device
+
+- freq : Frequency of the external oscillator clock in Hz (the frequency of
+	the amba bus in the ordinary case)
+
+- interrupts : Interrupt number for this device
+
+Optional properties:
+
+- systemid : If not present or if the value of the least significant 16 bits
+	of this 32-bit property is smaller than GRCAN_TXBUG_SAFE_GRLIB_VERSION
+	a bug workaround is activated.

 In the other hand PACKET_MMAP is very efficient. PACKET_MMAP provides a size 
 configurable circular buffer mapped in user space that can be used to either
 send or receive packets. This way reading packets just needs to wait for them,
 most of the time there is no need to issue a single system call. Concerning

+If you wish to put user data at a custom offset from the beginning of

+can set tp_net (with SOCK_DGRAM) or tp_mac (with SOCK_RAW). In order

-4.3) Timer-Driver Interrupt
-Instead of having the device that asynchronously notifies the frame receptions,
-the driver configures a timer to generate an interrupt at regular intervals.
-Based on the granularity of the timer, the frames that are received by the
-device will experience different levels of latency. Some NICs have dedicated
-timer device to perform this task. STMMAC can use either the RTC device or the

-The timers frequency can be passed to the driver as parameter; when change it,

-Several performance tests on STM platforms showed this optimisation allows to
-spare the CPU while having the maximum throughput.
+4.3) Interrupt Mitigation
+The driver is able to mitigate the number of its DMA interrupts
+using NAPI for the reception on chips older than the 3.50.
+New chips have an HW RX-Watchdog used for this mitigation.
+
+On Tx-side, the mitigation schema is based on a SW timer that calls the
+tx function (stmmac_tx) to reclaim the resource after transmitting the
+frames.
+Also there is another parameter (like a threshold) used to program
+the descriptors avoiding to set the interrupt on completion bit in
+when the frame is sent (xmit).

  * Notes on locking strategy:
  *
- * Most CSRs are 128-bit (oword) and therefore cannot be read or
- * written atomically.  Access from the host is buffered by the Bus
- * Interface Unit (BIU).  Whenever the host reads from the lowest
- * address of such a register, or from the address of a different such
- * register, the BIU latches the register's value.  Subsequent reads
- * from higher addresses of the same register will read the latched
- * value.  Whenever the host writes part of such a register, the BIU
- * collects the written value and does not write to the underlying
- * register until all 4 dwords have been written.  A similar buffering
- * scheme applies to host access to the NIC's 64-bit SRAM.
+ * Many CSRs are very wide and cannot be read or written atomically.
+ * Writes from the host are buffered by the Bus Interface Unit (BIU)
+ * up to 128 bits.  Whenever the host writes part of such a register,
+ * the BIU collects the written value and does not write to the
+ * underlying register until all 4 dwords have been written.  A
+ * similar buffering scheme applies to host access to the NIC's 64-bit
+ * SRAM.
  *
- * Access to different CSRs and 64-bit SRAM words must be serialised,
- * since interleaved access can result in lost writes or lost
- * information from read-to-clear fields.  We use efx_nic::biu_lock
- * for this.  (We could use separate locks for read and write, but
- * this is not normally a performance bottleneck.)
+ * Writes to different CSRs and 64-bit SRAM words must be serialised,

+ * We also serialise reads from 128-bit CSRs and SRAM with the same
+ * spinlock.  This may not be necessary, but it doesn't really matter
+ * as there are no such reads on the fast path.

+ * A Tx or Rx queue resides in host DRAM, and is comprised of a circular buffer
+ * of buffer descriptors, each of which points to one or more data buffers for
+ * the device to read from or fill.  Driver and device exchange status of each
+ * queue via "read" and "write" pointers.  Driver keeps minimum of 2 empty
+ * entries in each circular buffer, to protect against confusing empty and full
+ * queue states.
+ *
+ * The device reads or writes the data in the queues via the device's several
+ * DMA/FIFO channels.  Each queue is mapped to a single DMA channel.
+ *
+ * For Tx queue, there are low mark and high mark limits. If, after queuing
+ * the packet for Tx, free space become < low mark, Tx queue stopped. When
+ * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
+ * Tx queue resumed.

-/*************** DMA-QUEUE-GENERAL-FUNCTIONS  *****
- * DMA services
- *
- * Theory of operation
- *
- * A Tx or Rx queue resides in host DRAM, and is comprised of a circular buffer
- * of buffer descriptors, each of which points to one or more data buffers for
- * the device to read from or fill.  Driver and device exchange status of each
- * queue via "read" and "write" pointers.  Driver keeps minimum of 2 empty
- * entries in each circular buffer, to protect against confusing empty and full
- * queue states.
- *
- * The device reads or writes the data in the queues via the device's several
- * DMA/FIFO channels.  Each queue is mapped to a single DMA channel.
- *
- * For Tx queue, there are low mark and high mark limits. If, after queuing
- * the packet for Tx, free space become < low mark, Tx queue stopped. When
- * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
- * Tx queue resumed.

+ * Reads an shdlc frame from the chip. This is not as straightforward as it

+ * The frame format is len-data-crc, and corruption can occur anywhere while
+ * transiting on i2c bus, such that we could read an invalid len.
+ * In order to recover synchronization with the next frame, we must be sure
+ * to read the real amount of data without using the len byte. We do this by
+ * assuming the following:
+ * - 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.

- * that context only synchronization against system time (=
- * ktime_get_real()) is currently needed. But this utility code might
- * become useful in other situations, which is why it was written as
- * general purpose utility code.
- *
- * The source timecounter is assumed to return monotonically
- * increasing time (but this code does its best to compensate if that
- * is not the case) whereas target time may jump.
- *
- * The target time corresponding to a source time is determined by
- * reading target time, reading source time, reading target time
- * again, then assuming that average target time corresponds to source
- * time. In other words, the assumption is that reading the source
- * time is slow and involves equal time for sending the request and
- * receiving the reply, whereas reading target time is assumed to be
- * fast.
