title: TI OMAP Control PHY Module
maintainers:
- Roger Quadros <rogerq@ti.com>
description:
The TI OMAP Control PHY module is a hardware block within the system
control module (SCM) of Texas Instruments OMAP SoCs. It provides
centralized control over power, configuration, and auxiliary features
for multiple on-chip PHYs. This module is essential for proper PHY
operation in power-constrained embedded systems.
