[PATCH v2 0/3] STM32MP15 OTG params updates

From: Amelie Delaunay
Date: Tue Jan 05 2021 - 04:49:58 EST


This patchset brings some updates on STM32MP15 OTG HS and FS.
It sets ahbcfg parameter for both HS and FS as the value reported by the
hardware is not recommended.
It also disables Link Power Management on OTG HS because with some Host
controllers (at least seen with some USB 3.2 Gen2 controllers), OTG doesn't
succeed to exit L1 state.
It also enables FS/LS PHY clock selection when the Core is in FS Host mode,
to have 6MHz PHY clock when the connected device is LS, and 48Mhz PHY clock
otherwise.
