Subject: [PATCH 6/8] power: reset: at91-reset: add support for sam9x60 SoC
Date: Wed, 16 Jan 2019 10:57:42 +0100 [thread overview]
Message-ID: <7e68a0298b8802edaead1f9c011f9c2e191ecf6a.1547629763.git.nicolas.ferre@microchip.com> (raw)
In-Reply-To: <cover.1547629763.git.nicolas.ferre@microchip.com>
Add support for additional reset causes and the proper compatibility
string for sam9x60 SoC. The restart function is the same as the samx7.
