Subject: Re: [RFC PATCH] mxs: i2c: Implement arbitrary clock speed derivation algorithm
Date: Tue, 8 Jan 2013 19:14:00 +0100 [thread overview]

Dear Marek Vasut,
> This patch drops the i2c timing tables from this driver and instead
> derives the timing based from the requested clock sleep. The timing
> tables were completely wrong anyway when observed on a scope.
>
> This new algorithm is also only derived by using a scope, but it seems
> to produce much more accurate result.
