|

* The specification is all messed up dealing with sending

* multi-part messages. Per what the specification says, it
|
||||
* is impossible to send a message that is a multiple of 32
|
||||
* bytes, except for 32 itself. It talks about a "start"
|
||||
* transaction (cmd=6) that must be 32 bytes, "middle"
|
||||
* transaction (cmd=7) that must be 32 bytes, and an "end"
|
||||
* transaction. The "end" transaction is shown as cmd=7 in
|
||||
* the text, but if that's the case there is no way to
|
||||
* differentiate between a middle and end part except the
|
||||
* length being less than 32. But there is a table at the far
|
||||
* end of the section (that I had never noticed until someone
|
||||
* pointed it out to me) that mentions it as cmd=8.
|
||||
*
|
||||
* After some thought, I think the example is wrong and the
|
||||
* end transaction should be cmd=8. But some systems don't
|
||||
* implement cmd=8, they use a zero-length end transaction,
|
||||
* even though that violates the SMBus specification.
|
||||
*
|
||||
* So, to work around this, this code tests if cmd=8 works.
|
||||
* If it does, then we use that. If not, it tests zero-
|
||||
* byte end transactions. If that works, good. If not,
|
||||
* we only allow 63-byte transactions max.
