Subject: [PATCH v3 1/5] dt-bindings: phy: cadence-torrent: Add optional input reference clock for PLL1
Add a new optional input reference clock (pll1_refclk) for PLL1.
Update bindings to support dual reference clock multilink configurations.

description:
- PHY reference clock for 1 item. Must contain an entry in clock-names.
- Optional Parent to enable output reference clock.
+ PHY input reference clocks - refclk (for PLL0) & pll1_refclk (for PLL1).
+ pll1_refclk is optional and used for multi-protocol configurations requiring
+ separate reference clock for each protocol.
+ Same refclk is used for both PLL0 and PLL1 if no separate pll1_refclk is used.
+ Optional parent clock (phy_en_refclk) to enable a reference clock output feature
+ on some platforms to output either derived or received reference clock.
