Subject: [RFC PATCH v1 00/20] Review Request: Add support for Intel PMC
Date: Tue, 24 Aug 2021 22:17:41 +0530	[thread overview]
Message-ID: <20210824164801.28896-1-lakshmi.sowjanya.d@intel.com> (raw)

From: Lakshmi Sowjanya D <lakshmi.sowjanya.d@intel.com>

Starting with Intel(R) Tiger Lake and Elkhart Lake platforms the PMC
hardware adds the Timed I/O hardware interface.

The Timed I/O hardware implements some functionality similar to GPIO
with added timing logic that is driven by the Always Running Timer
(ART).

The Timed I/O Hardware implement 3 basic functions:
  * Input Timestamping
  * Single Shot Timed Output
  * Periodic Timed Output

 Please help to review the changes.

Thanks in advance,
Sowjanya
