I did not understand this comment? Do you want me to change something in patch? I had run checkpatch script on the patch before sending and it did not report any waning or error.

You mail server is using a content-transfer-encoding that makes patch applying very difficult. Talk to NXP colleague Anson Huang <Anson.Huang@nxp.com> to find out how to fix it. https://patchwork.kernel.org/patch/10944169/#22656941 Shawn

The qspi flash in ls1046a based QDS and RDB boards can operate at 50MHz frequency. Therefore, update the maximum supported freq in their respective dts files.
