Subject: Merge branch 'i2c/for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=32250e4a5fa0b618044afa59fba01093a4bcb14a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Merge branch 'i2c/for-4.5' of git://git./linux/kernel/git/wsa/linux

Pull i2c updates from Wolfram Sang:
 "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"
