Subject: [PATCH 5/7] clk: amlogic: Add S7 PLL clock controller driver
Date: Fri, 06 Nov 2026 09:30:28 +0100 [thread overview]
Message-ID: <20261106-upstream-s7-clk-v1-5-7d501d62621f@baylibre.com> (raw)
In-Reply-To: <20261106-upstream-s7-clk-v1-0-7d501d62621f@baylibre.com>
The S7 PLL controller provides the fixed PLL with its fclk dividers,
the GP0, HIFI0 and HIFI1 PLLs, and the HDMI PLL.
Add a driver for it. The GP0 and HIFI PLLs are expected to run with
their input divided by 2 (div0p5) and the HDMI PLL without it, as the
firmware and the init sequences set them up.
