[mynewt-nimble] 01/02: nimble/drivers/fem: Add support for nRF21540
This is an automated email from the ASF dual-hosted git repository.
andk pushed a commit to branch master
in repository https://gitbox.apache.org/repos/asf/mynewt-nimble.git
commit 9f99d55e64d492057425b455810b465dca8efd5b
Author: Andrzej Kaczmarek <an...@codecoup.pl>

nimble/drivers/fem: Add support for nRF21540
This adds support for nRF21540 FEM.
FEM is controlled via GPIOs, there's no support for SPI.
