Subject: [PATCH 2/5] clk: sunxi-ng: a64: Add constraints on PLL-MIPI's n/m ratio and parent rate
Date: Mon, 18 Dec 2023 14:35:20 +0100 [thread overview]
Message-ID: <20231218-pinephone-pll-fixes-v1-2-e238b6ed6dc1@oltmanns.dev> (raw)
In-Reply-To: <20231218-pinephone-pll-fixes-v1-0-e238b6ed6dc1@oltmanns.dev>
The Allwinner A64 manual lists the following constraints for the
PLL-MIPI clock:
- M/N >= 3
- (PLL_VIDEO0)/M >= 24MHz
Use these constraints.
