This patch splits i2c-designware.c into three pieces: i2c-designware-core.c, contains the code that interacts directly with the core. i2c-designware-platdrv.c, contains the code specific to the platform driver using the core. i2c-designware-core.h contains the definitions and declareations shared by i2c-designware-core.c and i2c-designware-platdrv.c. This patch is the first in a set to allow multiple instances of the designware I2C core in the system.

Don't let other driver config options influence us, as it makes the code more complex and fragile for a small benefit. There's nothing wrong with instantiating I2C devices even if they don't have a driver. And we're talking about 835 extra bytes in the binary on x86-64, that's hardly worth arguing about.

The Sodaville I2C controller is almost the same as found on PXA2xx. The difference: - the register are at a different offset - no slave support The PCI probe code adds three platform devices which are probed then by the platform code. The X86 part also adds dummy clock defines because we don't have HW clock support.

(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.wang@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.wang@intel.com>: Shared IRQ support Wen Wang <wen.w.wang@intel.com>: D3 support Fixes for OCT test runs Interrupt optimisations Hong Liu <hong.liu@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.
