Subject: [PATCH v4 00/15] PHY: Add support for multilink configurations in Cadence Sierra PHY driver

Cadence Sierra PHY is a multiprotocol PHY supporting different multilink
PHY configurations. This patch series extends functionality of Sierra PHY
driver by adding features like support for multilink multiprotocol
configurations, derived reference clock etc.

The changes have been validated on TI J721E platform.

Version History:

v4:
   - In 12/15, used swap() to make code cleaner. Also, added comments
     to describe PHY multilink configuration logic.
   - Updated commit message for 13/15.

v3:
   - Rebased on latest PHY next
   - Added Reviewed-by and Acked-by tags

v2:
   - Added a new patch 3/15 to rename the SSC macros for dt-bindings
     to use generic names. These macros are not yet used in any DTS file.
