Subject: [PATCH v3 1/2] dt-bindings: phy: phy-stm32-usbphyc: add #clock-cells property
Date: Mon, 8 Feb 2021 12:46:58 +0100 [thread overview]
Message-ID: <20210208114659.15269-2-amelie.delaunay@foss.st.com> (raw)
In-Reply-To: <20210208114659.15269-1-amelie.delaunay@foss.st.com>
usbphyc provides a unique clock called ck_usbo_48m.
STM32 USB OTG needs a 48Mhz clock (utmifs_clk48) for Full-Speed operation.
ck_usbo_48m is a possible parent clock for USB OTG 48Mhz clock.
ck_usbo_48m is available as soon as the PLL is enabled.
Signed-off-by: Amelie Delaunay <amelie.delaunay@foss.st.com>

Changes in v3:
- remove #clock-cells from required properties
