As it turns out, the set_cs() enable parameter refers to the logic level

This patch series implements large PEBS interrupt threshold.
Currently, the PEBS threshold is forced to set to one. A larger PEBS

PEBS always had the capability to log samples to its buffers without
an interrupt. Traditionally perf has not used this but always set the
PEBS threshold to one.

Flush the PEBS buffer during context switch if PEBS interrupt threshold
is larger than one. This allows perf to supply TID for sample outputs.

When the PEBS interrupt threshold is larger than one record and the
machine supports multiple PEBS events, the records of these events are
mixed up and we need to demultiplex them.
Demuxing the records is hard because the hardware is deficient. The
hardware has two issues that,

Add Broxton Lower Power Sub System Integrated DMA support, Since the
DMA register space is very similar to DesignWare DMA register space.
Add DW_DMAC_TYPE_IDMA type to distinguish LPSS iDMA register.
Broxton LPSS iDMA's maximum block size is 0x1(128KB -1).

There defined Whiskey Cove PMIC controller on one Intel platform,
and all registers on this PMIC are accessed by IPC commands.
This patch is to utilize regmap framework to access PMIC registers
for PMIC core and device drivers.
