This is second iteration of the patch series. First version is here: http://patchwork.ozlabs.org/patch/390694/ http://patchwork.ozlabs.org/patch/390695/ In order to get source clock to the core driver we need some way of creating it in the first place. For Intel LPSS it is done in drivers/acpi/acpi_lpss.c but that is not applicable for AMD I2C host controller which is too different from private parts to the LPSS one. We solve this by creating the clock in ACPI parts of the platform driver when we detect the AMD I2C host controller. Doing this requires small refactoring to be done to the probe() which is what patches [1-2/3] are doing. Changes to the previous version: * Rebased on top of i2c/for-next branch * New patch defaulting ACPI probe to fast mode * Instead of direct dependency to COMMON_CLK we depend on (ACPI && COMMON_CLK) || ACPI. (suggested by Wolfram) Carl, can you test that this still works on your machine?
