From aa62f85d0c65712c24b4892e9eab929d5176cee2 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Wed, 27 Oct 2010 12:44:03 +0100 Subject: i2c-intel-mid: support for Moorestown and Medfield platform (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 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 : Shared IRQ support Wen Wang : D3 support Fixes for OCT test runs Interrupt optimisations Hong Liu 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.
