This is a note to let you know that I've just added the patch titled clk: imx: clk-fracn-gppll: correct rdiv to the 5.18-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: clk-imx-clk-fracn-gppll-correct-rdiv.patch and it can be found in the queue-5.18 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 5c89dc4a2d88a026da28e971d9378d64a44d0bdc Author: Peng Fan <peng.fan@xxxxxxx> Date: Thu Jun 9 21:29:01 2022 +0800 clk: imx: clk-fracn-gppll: correct rdiv [ Upstream commit f300cb7fccf69ba1835b983c76d70deb818ad194 ] According to Reference Manual: 000b - Divide by 1 001b - Divide by 1 010b - Divide by 2 011b - Divide by 3 100b - Divide by 4 101b - Divide by 5 110b - Divide by 6 111b - Divide by 7 So only need increase rdiv by 1 when the register value is 0.
