+ Support for CAN cards from Softing Gmbh & some cards

+ Softing Gmbh CAN cards come with 1 or 2 physical busses.
+ Those cards typically use Dual Port RAM to communicate
+ with the host CPU. The interface is then identical for PCI
+ and PCMCIA cards. This driver operates on a platform device,
+ which has been created by softing_cs or softing_pci driver.
+ Warning:
+ The API of the card does not allow fine control per bus, but
+ controls the 2 busses on the card together.
+ As such, some actions (start/stop/busoff recovery) on 1 bus
+ must bring down the other bus too temporarily.

-The binding between hdpvr and lirc_zilog is currently disabled,

+The 'tx_only' lirc_zilog module parameter will allow ir-kbd-i2c
+and lirc_zilog to coexist in the kernel, if the user requires such a set-up.
+However the IR unit will not work well without coordination between the

+cards, which are not easily "hot unplugged", the imperfect state of reference
+counting and locking is acceptable if not correct. For USB connected units
+like HD PVR, PVR USB2, HVR-1900, and HVR1950, the likelyhood of an Ooops on
+unplug is probably great. Proper reference counting and locking needs to be
+implemented before this module is moved out of staging.
+
+3. The binding between hdpvr and lirc_zilog is currently disabled,
due to an OOPS reported a few years ago when both the hdpvr and cx18
drivers were loaded in his system. More details can be seen at:
http://www.mail-archive.com/linux-media@vger.kernel.org/msg09163.html
More tests need to be done, in order to fix the reported issue.
-There's a conflict between ir-kbd-i2c: Both provide support for RX events.
-Such conflict needs to be fixed, before moving it out of staging.
+4. In addition to providing a shared mutex for transceiver access
+locking, bridge drivers, if able, should provide a chip reset() callback
+to lirc_zilog via struct IR_i2c_init_data. cx18 and ivtv already have routines
+to perform Z8 chip resets via GPIO manipulations. This will allow lirc_zilog
+to bring the chip back to normal when it hangs, in the same places the
+original lirc_pvr150 driver code does. This is not strictly needed, so it
+is not required to move lirc_zilog out of staging.
+
+5. Both lirc_zilog and ir-kbd-i2c support the Zilog Z8 for IR, as programmed
+and installed on Hauppauge products. When working on either module, developers
+must consider at least the following bridge drivers which mention an IR Rx unit
+at address 0x71 (indicative of a Z8):
-The way I2C probe works, it will try to register the driver twice, one
-for RX and another for TX. The logic needs to be fixed to avoid such
-issue.
