There are some ABI documents that, while they don't generate any warnings, they have issues when parsed by get_abi.pl script on its output result. Address them, in order to provide a clean output.

Description:
|
|
On reading represents the current state of the bus. If it
|
|
contains a "0" the bus is stopped and connected devices are
|
|
expected to not do anything because their watchdog triggered.
|
|
When the file contains a "1" the bus is operated and periodically
|
|
does a push-pull cycle to write and read data from the
|
|
connected devices.
|
|
|
|
When writing a "0" or "1" the bus moves to the described state.

Write-only file. Write
|
|
|
|
<type> <inbytes> <outbytes> <statustype>
|
|
|
|
to add a new device dynamically. <type> is the name that is used to match
|
|
to a driver (similar to the platform bus). <inbytes> and <outbytes> define
|
|
the length of the input and output shift register in bytes respectively.
|
|
|
|
<statustype> defines the 4 bit device type that is check to identify connection
|
|
problems.
|
|
|
|
The new device is added to the end of the existing chain.
