[PATCH RFC 0/2] Introduce ddr[3-4]-channel binding

[Clément Le Goffic]

This series aims to request comments for the ddr-channel binding as I'll
need them for the stm32-ddr-pmu driver.
The V1 of the driver and a start of discussion can be found here:
https://lore.kernel.org/r/20250623-ddrperfm-upstream-v1-0-7dffff168090@foss.st.com

The first patch contains a base of binding, which I find sufficient for
my needs but perhaps you'll have suggestion for addition or rework as this is
mainly inspirate from lpddrX-channel binding.
As we can find the same property in the two channel binding maybe this can be
shared properties.

The second patch, that contains stm32-ddr-pmu binding, aims to provide an
example of usage of this ddr-channel bindings.
Note the "memory-channel" property which I mainly want to discuss about
and gather some feedbacks.

For your knowledge, the stm32-ddr-pmu driver (DDRPERFM peripheral) needs
the dram type information for its internal working with ddr events.
