Subject: [PATCH 3/8] dt-bindings: reset: atmel,at91sam9260-reset: add sama7g5 bindings
Date: Tue, 5 Apr 2022 14:27:19 +0300 [thread overview]
Message-ID: <20220405112724.2760905-4-claudiu.beznea@microchip.com> (raw)
In-Reply-To: <20220405112724.2760905-1-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).
