Subject: [PATCH RFC v4 12/12] ARM: dts: zte: Add a syscon-reboot for zx297520v3 boards
Date: Tue, 16 Jun 2026 23:26:32 +0300 [thread overview]
Message-ID: <20260616-zx29clk-v4-12-ca994bd22e9d@gmail.com> (raw)
In-Reply-To: <20260616-zx29clk-v4-0-ca994bd22e9d@gmail.com>
This is fairly simple with the driver exposing a syscon regmap. Write a
one to the lowest bit of register 0 and the board resets.
