ACPI / LPSS: register clock device for Lynxpoint DMA properly
The DMA controller in Lynxpoint is enumerated as a regular ACPI device now. To work properly it is using the LPSS root clock as a functional clock. That's why we have to register the clock device accordingly to the ACPI ID of the DMA controller. The acpi_lpss.c module is responsible to do the job. This patch also removes hardcoded name of the DMA device in clk-lpt.c and the name of the root clock in acpi_lpss.c. Signed-off-by: Rafael J.
