Subject: [PATCH RFC v4 11/12] ARM: dts: zte: Declare zx297520v3 clock device nodes
Date: Tue, 16 Jun 2026 23:26:31 +0300 [thread overview]
Message-ID: <20260616-zx29clk-v4-11-ca994bd22e9d@gmail.com> (raw)
In-Reply-To: <20260616-zx29clk-v4-0-ca994bd22e9d@gmail.com>
This makes use of the driver added in the previous patches. It wires up
the uart clocks and resets and allows getting rid of the placeholder
uartclk node.
