This is an automated email from the ASF dual-hosted git repository.
jerzy pushed a commit to branch master
in repository https://gitbox.apache.org/repos/asf/mynewt-core.git
commit 87bdcafef85d6dfd7167bbbd17124bfe26dcb356
Author: Jerzy Kasenberg <je...@codecoup.pl>

tinyusb: Add hardware initialization for stm32l0
TinyUSB uses same driver for STM32L0 as for STM32F1 but there
are differences in interrupts and power settings that call
for separate package.
