[PATCH 01/17] dt-bindings: clock: google,gs101-clock: add HSI2 clock management unit

From: Peter Griffin
Date: Thu Apr 04 2024 - 08:28:20 EST


Add dt schema documentation and clock IDs for the High Speed Interface
2 (HSI2) clock management unit. This CMU feeds high speed interfaces
such as PCIe and UFS.
