Subject: [PATCH v2 14/15] ARM: dts: microchip: sama7d65: Add Reset and Shutdown and PM support
Date: Mon, 10 Feb 2025 14:13:14 -0700 [thread overview]
Message-ID: <d8578cb635ff5b01e42132bd40a12b31c8638800.1739221064.git.Ryan.Wanner@microchip.com> (raw)
In-Reply-To: <cover.1739221064.git.Ryan.Wanner@microchip.com>
From: Ryan Wanner <Ryan.Wanner@microchip.com>
Add support for reset controller, wake up alarm timers, and shutdown
controller.
Add SRAM, SFR, secumod, UDDRC, and DDR3phy to enable support for low power modes.
