[PATCH 1/3] usb: dwc2: set ahbcfg parameter for STM32MP15 OTG HS and FS

2020-11-23 Thread Amelie Delaunay
STM32MP15 ahbcfg register default value sets Burst length/type (HBSTLEN) to Single (32-bit accesses on AHB), which is not recommended, according to STM32MP157 Reference manual [1]. This patch sets Burst length/type (HBSTLEN) so that bus transactions target 16x32 bit accesses. This improves OTG
