Bulk convert all DOS line endings to UNIX.
For the git migration we want a nice clean repository with UNIX line endings. git does not use svn:eol-style, we just need the file contents to be sane. Sorry everybody. I know this messes up blame. Scumbag *NIX developer says migrating to git will make line ending issues go away; commits giant change to svn which changes line endings anyway. :) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30924 a1c6a512-1295-4272-9138-f99709370657

Both the i2c_read and i2c_write function take the following arguments:
|
||||
* slave, the address of the i2c slave device to read from / write to
|
||||
* address, optional sub-address in the i2c slave (unused if -1)
|
||||
* len, number of bytes to be transfered
|
||||
* data, pointer to data to be transfered
|
||||
A return value < 0 indicates an error.
|
||||
|
||||
Note:
|
||||
* blocks the calling thread for the entire duraton of the i2c transfer but
|
||||
uses wakeup_wait/wakeup_signal to allow other threads to run.
|
||||
* ACK from slave is not checked, so functions never return an error
