Gunar Schorcht	c628486f5f	cpu/stm32: enable HSI48 for periph_usbdev	2023-07-05 09:40:24 +02:00
Gunar Schorcht	4a0b6a0cb2	cpu/stm32: fix RNG clock configuration for STM32U5 ... The RNG can use HSI48, HSI48/2 or HSI16. Using MSI as 48 MHz clock source for RNG is not possible. The clock configuration in `stmclk_u5.c` activates anyway only the MSIS but not the MSIK which could be used for certain peripherals. Therefore, this commit - removes the configuration of MSI as 48 MHz clock for RNG and its selection in `RCC->CCIPR1.ICLKSEL` - enables HSI48 and selects it for RNG. The HSI48 will also be used in future for certain peripherals such as USB OTG FS and SDMMC.	2023-07-04 18:07:15 +02:00
