Subject: [PATCH V2 1/7] clk: imx: fracn-gppll: fix the rate table
Date: Mon,  3 Apr 2023 15:13:03 +0800	[thread overview]
Message-ID: <20230403071309.3113513-2-peng.fan@oss.nxp.com> (raw)
In-Reply-To: <20230403071309.3113513-1-peng.fan@oss.nxp.com>

From: Peng Fan <peng.fan@nxp.com>

The Fvco should be range 2.4GHz to 5GHz, the original table voilate the
spec, so update the table to fix it.

Fixes: c196175acdd3 ("clk: imx: clk-fracn-gppll: Add more freq config for video pll")
Fixes: 044034efbeea ("clk: imx: clk-fracn-gppll: fix mfd value")
Fixes: 1b26cb8a77a4 ("clk: imx: support fracn gppll")
