Subject: [PATCH 1/1] ARM: dts: stm32: adjust USB OTG gadget fifo sizes in stm32mp151
Date: Tue, 10 Nov 2020 14:10:59 +0100 [thread overview]
Message-ID: <20201110131059.7826-1-amelie.delaunay@st.com> (raw)
Defaut use case on stm32mp151 USB OTG is ethernet gadget, using EP1 bulk
endpoint (MPS=512 bytes) and EP2 interrupt endpoint (MPS=16 bytes).
This patch optimizes USB OTG FIFO sizes accordingly.
