Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab...
Linus Torvalds [Thu, 18 Oct 2012 23:10:42 +0000 (16:10 -0700)]
Pull media fixes from Mauro Carvalho Chehab:
 "Media fixes for:
   - one Kconfig fix patch;
   - one patch fixing DocBook breakage due to the drivers/media UAPI
     changes;
   - the remaining UAPI media changes (DVB API).

  I'm aware that is is a little late for the UAPI renames for the DVB
  API, but IMHO, it is better to merge it for 3.7, due to two reasons:

   1) There is a major rename at 3.7 (not only uapi changes, but also
      the entire media drivers were reorganized on 3.7, in order to
      simplify the Kconfig logic, and easy drivers selection, especially
      for hybrid devices).  By confining all those renames there at 3.7
      it will cause all the harm at for media developers on just one
      shot.  Stable backports upstream and at distros will likely
      welcome it as well, as they won't need to check what changed on
      3.7 and what was postponed for on 3.8.

   2) The V4L2 DocBook Makefile creates a cross-reference between the
      media API headers and the specs.  This helps us _a_lot_ to be sure
      that all API improvements are properly documented.  Every time a
      header changes from one place to another, DocBook/media/Makefile
      needs to be patched.  Currently, the DocBook breakage patch
      depends on the DVB UAPI."

-The SMBus Driver
-----------------
-
-The SMBus driver allows up to 4 SMBus devices to be configured in the
-system.  By default, the driver will register any SMBus interfaces it finds
-in the I2C address range of 0x20 to 0x4f on any adapter.  You can change this
-at module load time (for a module) with:
-
-  modprobe ipmi_smb.o
-       addr=<adapter1>,<i2caddr1>[,<adapter2>,<i2caddr2>[,...]]
-       dbg=<flags1>,<flags2>...
-       [defaultprobe=1] [dbg_probe=1]
-
-The addresses are specified in pairs, the first is the adapter ID and the
-second is the I2C address on that adapter.
-
-The debug flags are bit flags for each BMC found, they are:
-IPMI messages: 1, driver state: 2, timing: 4, I2C probe: 8
-
-Setting smb_defaultprobe to zero disabled the default probing of SMBus
-interfaces at address range 0x20 to 0x4f.  This means that only the
-BMCs specified on the smb_addr line will be detected.
-
-Setting smb_dbg_probe to 1 will enable debugging of the probing and
-detection process for BMCs on the SMBusses.
-
-Discovering the IPMI compliant BMC on the SMBus can cause devices
-on the I2C bus to fail. The SMBus driver writes a "Get Device ID" IPMI
-message as a block write to the I2C bus and waits for a response.
-This action can be detrimental to some I2C devices. It is highly recommended
-that the known I2c address be given to the SMBus driver in the smb_addr
-parameter. The default address range will not be used when a smb_addr
-parameter is provided.
-
-When compiled into the kernel, the addresses can be specified on the
-kernel command line as:
-
-  ipmb_smb.addr=<adapter1>,<i2caddr1>[,<adapter2>,<i2caddr2>[,...]]
-       ipmi_smb.dbg=<flags1>,<flags2>...
-       ipmi_smb.defaultprobe=0 ipmi_smb.dbg_probe=1
-
-These are the same options as on the module command line.
-
-Note that you might need some I2C changes if CONFIG_IPMI_PANIC_EVENT
-is enabled along with this, so the I2C driver knows to run to
-completion during sending a panic event.
