Vendor: STMicroelectronics

Description

STM32U5 OTG HS PHY.

This binding is to be used by the STM32U5xx transceivers which are built-in
with USB HS PHY IP and a configurable HSE clock source.

Properties

Properties not inherited from the base binding file.

#phy-cells

int

Number of cells in a PHY provider. The meaning those
cells is defined by the binding for the phy node.

This property is required.

clock-reference

string

OTG_HS PHY reference clock frequency selection.

This value selects the reference clock frequency to be used in the OTG_HS PHY PLL
in the SYSCFG OTG_HS PHY register (SYSCFG_OTGHSPHYCR). The selection of this value
should take in consideration the OTGHSSEL dependency to avoid miss configurations.

This property is required.

Legal values: 'SYSCFG_OTG_HS_PHY_CLK_16MHz', 'SYSCFG_OTG_HS_PHY_CLK_19.2MHz', 'SYSCFG_OTG_HS_PHY_CLK_20MHz', 'SYSCFG_OTG_HS_PHY_CLK_24MHz', 'SYSCFG_OTG_HS_PHY_CLK_26MHz', 'SYSCFG_OTG_HS_PHY_CLK_32MHz'
