Subject: [PATCH v4 0/5] PHY: Add support for dual refclk configurations in Cadence Torrent PHY driver

This patch series extends Torrent PHY driver functionality to support
dual input reference clocks.

It also adds support for following multilink configurations:
- PCIe(100MHz) + USXGMII(156.25MHz)
- USXGMII(156.25MHz) + SGMII/QSGMII(100MHz)

The changes have been validated on TI J721E and J7200 platforms.

v1 of the patch series can be found at [1].

Version History:

v4:
   - Fixed error handling in patch 2/5 as per review comments for v3
   - Added Acked-by and Reviewed-by tags

v3:
   - Updated clock description in DT documentation
   - Added Acked-by from Conor

v2:
   - Rename refclk1 to pll1_refclk in bindings and in driver
   - Simplify clock-names as suggested by Rob
