Fix up trivial conflicts (other header files, and removal of the ab3550 mfd driver) in
- drivers/media/dvb/frontends/dibx000_common.c
- drivers/media/video/{mt9m111.c,ov6650.c}
- drivers/mfd/ab3550-core.c

Add RapidIO mport driver for IDT TSI721 PCI Express-to-SRIO bridge device.
The driver provides full set of callback functions defined for mport
devices in RapidIO subsystem. It also is compatible with current version
of RIONET driver (Ethernet over RapidIO messaging services).
This patch is applicable to kernel versions starting from 2.6.39.

The discovered bit in PGCCSR register indicates if the device has been
discovered by system host. In Rapidio systems, some agent devices can also
be master devices. They can issue requests into the system.

Upon the trial removal of the implicit presence of module.h,
lots of files showed up that were getting the sub-includes
by default without calling them out. Fix them in advance.

Replace/remove use of RIO v.1.2 registers/bits that are not
forward-compatible with newer versions of RapidIO specification.
RapidIO specification v.1.3 removed Write Port CSR, Doorbell CSR,
Mailbox CSR and Mailbox and Doorbell bits of the PEF CAR.
Use of removed (since RIO v.1.3) register bits affects users of
currently available 1.3 and 2.x compliant devices who may use not so
recent kernel versions.
Removing checks for unsupported bits makes corresponding routines
compatible with all versions of RapidIO specification. Therefore,
backporting makes stable kernel versions compliant with RIO v.1.3 and
later as well.

Add new sysfs attributes.
1. Routing information required to to reach the RIO device:
destid - device destination ID (real for for endpoint, route for switch)
hopcount - hopcount for maintenance requests (switches only)
2. device linking information:
lprev - name of device that precedes the given device in the enumeration
or discovery order (displayed along with of the port to which it
is attached).
lnext - names of devices (with corresponding port numbers) that are
attached to the given device as next in the enumeration or
discovery order (switches only)

Change the way how switchid value is set. Local counter variable does not
provide unified way to identify switch devices in a system with multiple
processors. Using local counter leads to the situation when the same RIO
switch has different switch ID for each processor. Replacing local
counter with unique portion of the Component Tag provides unified
reference to the switch by every processor in the system.

The size calculation is done incorrectly here because it should include
both the start and end (end - start + 1). It's easiest to just use
resource_size() which does the right thing.
I was worried there was something non-standard going on because the
printk() subtracts "end - 1", but the rest of the file uses the normal
resource size calculations. This function is only called from
fsl_rio_setup() in arch/powerpc/sysdev/fsl_rio.c and the calculation
there is also:
port->iores.start = law_start;
port->iores.end = law_start + law_size - 1;
So I think this is the correct fix.

Detects RIO link to the already enumerated device and properly sets links
between device objects. Changes to the enumeration/discovery logic:
1. Use Master Enable bit to signal end of the enumeration - agents may
start their discovery process as soon as they see this bit set
(Component Tag register was used before for this purpose).
2. Enumerator sets Component Tag (!= 0) immediately during device
setup. This allows to identify the device if the redundant route
exists in a RIO system.

This set of RapidIO patches extends support for standard error recovery
mechanism and adds new IDT Gen2 sRIO switch devices - CPS-1848 and
CPS-1616. Implementation of the standard error-stopped state recovery
mechanism (as defined by the RapidIO specification) is required for the
new switches.
Version 2 of this set of patches addresses received comments and fixes an
error notification setup issue found in the idt_gen2.c after the first
version was released.
This patch:
Make RapidIO devices appear in /sys/devices/rapidio directory instead of
top of /sys/devices directory.
