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. --- Changes in v2: - Move author mail address from @st.com to @foss.st.com - Add Minas' Reviewed-by on all patches Amelie Delaunay (3): usb: dwc2: set ahbcfg parameter for STM32MP15 OTG HS and FS usb: dwc2: enable FS/LS PHY clock select on STM32MP15 FS OTG usb: dwc2: disable Link Power Management on STM32MP15 HS OTG drivers/usb/dwc2/params.c | 8 ++++++++ 1 file changed, 8 insertions(+)
