Linus,
here is the I2C pull request with the following main points:
* I2C core now reports proper OF style module alias. I'd like to repeat
the note from the commit msg here (Thanks, Javier!):
===
NOTE: This patch may break out-of-tree drivers that were relying on this
behavior, and only had an I2C device ID table even when the device
was registered via OF. There are no remaining drivers in mainline
that do this, but out-of-tree drivers have to be fixed and define
a proper OF device ID table to have module auto-loading working.
===
* new driver for the SynQuacer I2C controller
* major refactoring of the QUP driver
* the piix4 driver now uses request_muxed_region which should fix a long
standing resource conflict with the sp5100_tco watchdog
* a bunch of small core & driver improvements
The patch touching sh-architecture doesn't have an ack, we tried for months to
reach the maintainers. As I didn't want to block this improvement any further
and the change is small, I applied it. I am still open for any discussion about
it.
Please pull.
Thanks,
Wolfram
