Subject: [PATCH v2 1/5] dt-bindings: clock: google,gs101-clock: add HSI2
clock management unit
From: Peter Griffin <peter.griffin@...aro.org>
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.
Signed-off-by: Peter Griffin <peter.griffin@...aro.org>
Reviewed-by: André Draszik <andre.draszik@...aro.org>
Reviewed-by: Rob Herring (Arm) <robh@...nel.org>
[AD: keep CMUs in google,gs101.h sorted alphabetically, and resolve
minor merge conflicts in google,gs101-clock.yaml]
