This patch set adds the clock for snvs module on imx8mn.
DT bindings, clk driver are updated accordingly.
DT for imx8mn (snvs-rtc-lp node) is also updated.
Horia Geantă (3):
dt-bindings: clock: imx8mn: add SNVS clock
clk: imx8mn: add SNVS clock to clock tree
arm64: dts: imx8mn: add clock for snvs rtc node

i.mx8mn has support for clock gating the snvs module.
Add it into clock tree so that rtc-snvs driver could use it.
Note this will also be required in the snvs_pwrkey driver,
once support for clock management will be added.

Initial commit adding imx8mn support:
6c3debcbae47 ("arm64: dts: freescale: Add i.MX8MN dtsi support")
added the "clock-names" property for the snvs rtc node,
however it missed adding the clock.

Add a commit message please.
Note, this modifies the devicetree ABI.
