Subject: [PATCH 0/2] clocksource: sysctr: add nxp,no-divider property

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

Legacy design used in i.MX8M* has a internal divider, but new design
used in i.MX9* not has that divider. So add a property to indicate
the divider exists or not.

I thought to extend the binding such as nxp,imx93-sysctr-timer, and
update driver to support i.MX93, then no need to add nxp,no-divider.
But this means we need to extend the binding again when add new SoC,
saying imx9[x].

Not very sure which is better, so just post the NXP downstream way.
