[PULL REQUEST] i2c for 5.2

[PULL REQUEST] i2c for 5.2

[Wolfram Sang]

[-- Attachment #1: Type: text/plain, Size: 11680 bytes --]

Linus,

I2C has for you:

* API for late atomic transfers (e.g. to shut down via PMIC). We have a
  seperate callback now which is called under clearly defined
  conditions. In-kernel users are converted, too.
* new driver for the AMD PCIe MP2 I2C controller
* large refactoring for at91 and bcm-iproc (both gain slave support
  due to this)
* and a good share of various driver improvements anf fixes

Please pull.

Thanks,

   Wolfram

Linus,

[PULL REQUEST] i2c for 5.2

[Wolfram Sang]

[-- Attachment #1: Type: text/plain, Size: 2055 bytes --]

Linus,

here are some I2C core API additions which are kind of simple but
enhance error checking for users a lot, especially by returning errno
now. There are wrappers to still support the old API but it will be
removed once all users are converted.

This comes a bit later in a seperate pull request because of my recent
illness. It would be great to have it merged in this cycle, however, so
we can start converting the users (spread across many subsystems) right
away.

Thanks,

   Wolfram
