[PATCH] arm64: dts: imx8: Fix lvds0 device tree

[Diogo Silva]

Hey,

Sorry for the broken tag, will fix on a resend.

As for the naming, if there is any reason for them to be named qm_*
it's totally fine, I'll revert it and only touch the clock names. I
changed them because comparing with lvds1, those ones do not contain
the qm_ prefix and I don't see how this dtsi relates specifically to
the imx8qm, since it is a imx8-ss... and not imx8qm-ss...
I didn't quite get the question about the nodes. Could you elaborate? Thanks

Best regards,
Diogo
