 Obviously, all controls in the cluster array must be initialized to either

+each control. For example, in the case of a volume/mute cluster the 'is_new'
+flag of the mute control would be set if the user called VIDIOC_S_CTRL for
+mute only. If the user would call VIDIOC_S_EXT_CTRLS for both mute and volume

-The binding between hdpvr and lirc_zilog is currently disabled,
+1. Both ir-kbd-i2c and lirc_zilog provide support for RX events.
+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
+two modules.  A shared mutex, for transceiver access locking, needs to be
+supplied by bridge drivers, in struct IR_i2_init_data, to both ir-kbd-i2c
+and lirc_zilog, before they will coexist usefully.  This should be fixed
+before moving out of staging.
+
+2. References and locking need careful examination.  For cx18 and ivtv PCI
+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:

 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.
 
-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.
+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):
