Subject: Re: [PATCH v3 07/13] clk: eyeq: Skip post-divisor when computing PLL frequency
Date: Mon, 23 Mar 2026 17:26:21 -0700 [thread overview]
Message-ID: <177431198100.5403.717221121672959530@lazor> (raw)
In-Reply-To: <20260226-eyeq6lplus-v3-7-9cbeb59268b0@bootlin.com>
Quoting Benoît Monin (2026-02-26 05:33:51)
> The output of the PLL is routed before the post-divisor so it should be
> ignored when computing the frequency of the PLL, functional change is
> implemented to reflect how the clock signal is wired internally.
>
> For the PLL of the EyeQ5, EyeQ6L, and EyeQ6H, this change has no impact
> as the post-divisor is either reported as disabled or set to 1. The PLL
> frequency is the same before and after the post-divisor.
>
> For the PLL in EyeQ6Lplus, however, the post-divisor is not 1, so it must
> be ignored to compute the correct frequency.
