(Updated to address Ben's comments. With regard to the message segment
restriction it's not something we hit on the actual platform so while
I will investigate that further I don't think its a blocker to submission.
At worst its a spot over-restrictive)
From: Wen Wang wen.w.w...@intel.com
Initial release of the driver. Updated and verified on hardware.
Cleaned up as follows
Alan Cox:
Squash down the switches into tables, and use the PCI ident field. We
could perhaps take this further and put the platform and port number into
this.
uint32t - u32
bracketing of case statements
spacing and '!' usage
Check the speed (which is now 0/1/2) is valid and ignore otherwise.
Fix remaining problems/suggestions from Jean's review
Fix items from Ben's review
Arjan van de Ven:
Initial power management hooks
Yong Wang youg.y.w...@intel.com:
Shared IRQ support
Wen Wang wen.w.w...@intel.com:
D3 support
Fixes for OCT test runs
Interrupt optimisations
Hong Liu hong@intel.com
The runtime PM code is working on the wrong device (i2c_adapter-dev).
The correct one should be pci_dev-dev. This breaks attached i2c
slave devices with runtime PM enabled. Slave device needs to runtime
resume parent device before runtime resuming itself, but we always get
error since we don't have pm_runtime callback for i2c_adapter-dev.
Bin Yang bin.y...@intel.com:
Update speed table
Saadi Maalem saadi.maa...@intel.com:
Clear all interrupts in the hardware init
Celine Chotard celinex.chot...@intel.com:
Correct ordering of clear/disable of IRQs
