Subject: [PATCH v5 3/9] dt-bindings: reset: atmel,at91sam9260-reset: add sama7g5 bindings
Date: Fri, 10 Jun 2022 12:24:08 +0300	[thread overview]
Message-ID: <20220610092414.1816571-4-claudiu.beznea@microchip.com> (raw)
In-Reply-To: <20220610092414.1816571-1-claudiu.beznea@microchip.com>

Add documentation for SAMA7G5 reset controller. Compared with previous
versions of reset controllers this one contains support for resetting
in SoC devices (e.g. USB PHYs).
