[PATCH 2/4] ARM: at91: handle CONFIG_PM for armv7m configurations Alexandre Belloni <alexandre.belloni@free-electrons.com> - 2016-09-23 00:30 +0200

| Subject | [PATCH 2/4] ARM: at91: handle CONFIG_PM for armv7m configurations |
| Message-ID | <skkFb-3MU-1@gated-at.bofh.it> |
There is currently no PM support for samx7 but the symbol can still be
selected. This avoids compilation issues.
