Linus,
here is the pull request for the 4.5 merge window. Quite some driver
updates:
* piix4 can now handle multiplexed adapters
* brcmstb, xlr, eg20t, designware drivers support more SoCs
* emev2 gained i2c slave support
* img-scb and rcar got bigger refactoring to remove issues
* lots of common driver updates
i2c core changes:
* new quirk flag when an adapter does not support clock stretching, so
clients can be configured to avoid that if possible
* added a helper function to retrieve timing parameters from firmware
(with rcar being the first user)
* "multi-master" DT binding added so drivers can adapt to this setting
(like disabling PM to keep arbitration working)
* RuntimePM for the logical adapter device is now always enabled by the
core to ensure propagation from childs to the parent (the HW device)
* new macro builtin_i2c_driver to reduce boilerplate
Please pull.
Thanks,
Wolfram
